William Barton Rogers was born at Philadelphia, on the 7th of December,
1804. His father, Patrick Kerr Rogers, was a native of Newton Stewart,
in the north of Ireland; but while a student at Trinity College, Dublin,
becoming an object of suspicion on account of his sympathy with the
Rebellion of 1798, he emigrated to this country, and finished his
education in the University of Pennsylvania, at Philadelphia, where he
received the degree of Doctor of Medicine.
Here he married Hannah Blythe, a Scotch lady--who was at the time living
with her aunt, Mrs. Ramsay--and settled himself in his profession in a
house on Ninth Street, opposite to the University; and in this house
William B. Rogers was born. He was the second of four sons--James,
William, Henry, and Robert--all of whom became distinguished as men of
science.
Patrick Kerr Rogers, finding that his prospects of medical practice in
Philadelphia had been lessened in consequence of a protracted absence in
Ireland, made necessary by the death of his father, removed to
Baltimore; but soon afterward accepted the Professorship of Chemistry
and Physics in William and Mary College, Virginia, made vacant by the
resignation of the late Robert Hare; and it is a fact worthy of notice
that, while he succeeded Dr. Hare at William and Mary College, his
eldest son, James, succeeded Dr. Hare at the University of Pennsylvania.
At William and Mary College the four brothers Rogers were educated; and
on the death of the father, at Ellicott Mills, in 1828, William B.
Rogers succeeded to the professorship thus made vacant.
He had already earned a reputation as a teacher by a course of lectures
before the Maryland Institute in Baltimore during the previous year, and
after his appointment at once entered on his career as a scientific
investigator. At this period he published a paper on "Dew," and, in
connection with his brother Henry, another paper on the "Voltaic
Battery"--both subjects directly connected with his professorship. But
his attention was early directed to questions of chemical geology; and
he wrote, while at William and Mary College, a series of articles for
the "Farmer's Register" on the "Green Sands and Marls of Eastern
Virginia," and their value as fertilizers. Next we find the young
professor going before the Legislature of Virginia, and, while modestly
presenting his own discoveries, making them the occasion for urging upon
that body the importance of a systematic geological survey for
developing the resources of the State. So great was the scientific
reputation that Professor Rogers early acquired by such services, that
in 1835 he was called to fill the important Professorship of Natural
Philosophy and Geology in the University of Virginia; and during the
same year he was appointed State Geologist of Virginia, and began those
important investigations which will always associate his name with
American geology.
Professor Rogers remained at the head of the Geological Survey of
Virginia until it was discontinued, in 1842, and published a series of
very valuable annual reports. As was anticipated, the survey led to a
large accumulation of material, and to numerous discoveries of great
local importance. As this was one of the earliest geological surveys
undertaken in the United States, its directors had in great measure to
devise the methods and lay out the plans of investigation which have
since become general. This is not the place, however, for such details;
but there are four or five general results of Professor Rogers's
geological work at this period which have exerted a permanent influence
on geological science, and which should therefore be briefly noticed.
Some of these results were first published in the "American Journal of
Science"; others were originally presented to the Association of
American Geologists and Naturalists, and published in its
"Transactions." Professor Rogers took a great interest in the
organization of this association in 1840, presided over its meeting in
1845, and again, two years later, when it was expanded into the American
Association for the Advancement of Science.
In connection with his brother Robert, Professor William B. Rogers was
the first to investigate the solvent action of water--especially when
charged with carbonic acid--on various minerals and rocks; and by
showing the extent of this action in nature, and its influence in the
formation of mineral deposits of various kinds, he was one of the first
to observe and interpret the important class of facts which are the
basis of chemical geology.
Another important result of Professor Rogers's geological work was to
show that the condition of any coal-bed stands in a close genetic
relation to the amount of disturbance to which the enclosing strata have
been submitted, the coal becoming harder and containing less volatile
matter as the evidence of disturbance increases. This generalization,
which seems to us now almost self-evident--understanding, as we do, more
of the history of the formation of coal--was with Professor Rogers an
induction from a great mass of observed facts.
By far, however, the most memorable contribution of Professor Rogers to
geology was that made in connection with Henry D. Rogers, in a paper
entitled "The Laws of Structure of the more Disturbed Zones of the
Earth's Crust," presented by the two brothers at the meeting of the
Association of American Geologists and Naturalists, held at Boston in
1842. This paper was the first presentation of what may be called in
brief the "Wave Theory of Mountain Chains." This theory was deduced by
the brothers Rogers from an extended study of the Appalachian Chain in
Pennsylvania and Virginia, and was supported by numerous geological
sections and by a great mass of facts. The hypothesis which they offered
as an explanation of the origin of the great mountain waves may not be
generally received; but the general fact, that the structure of mountain
chains is alike in all the essential features which the brothers Rogers
first pointed out, has been confirmed by the observations of Murchison
in the Ural, of Darwin in the Andes, and of the Swiss geologists in the
Alps. "In the Appalachians the wave structure is very simple, and the
same is true in all corrugated districts where the crust movements have
been simple, and have acted in one direction only. But where the
elevating forces have acted in different directions at different times,
causing interference of waves like a chopped sea, as in the Swiss Alps
and the mountains of Wales or Cumberland, the undulations are disguised,
and are with extreme difficulty made out." The wave theory of mountain
chains was the first important contribution to dynamical and structural
geology which had been brought forward in this country. It excited at
the time great interest, as well from the novelty of the views as from
the eloquence with which they were set forth; and to-day it is still
regarded as one of the most important advances in orographic geology.
A marked feature of mountain regions is that rupturing of the strata
called faults; and another of the striking geological generalizations of
the brothers Rogers is what may be called the law of the distribution of
faults. They showed that faults do not occur on gentle waves, but in the
most compressed flexures of the mountain chains, which in the act of
moving have snapped or given way at the summit where the bend is
sharpest, the less inclined side being shoved up on the plane of the
fault, this plane being generally parallel to, if it does not coincide
with, the axis plane; and, further, that "the direction of these faults
generally follows the run of the line of elevation of the mountains, the
length and vertical displacement depending on the strength of the
disturbing force."
The last of the general geological results to which we referred above
was published under the name of William B. Rogers only. It was based on
the observed positions of more than fifty thermal springs in the
Appalachian belt, occurring in an area of about fifteen thousand square
miles, which were shown to issue from anticlinal axes and faults, or
from points very near such lines; and in connection with these springs
it was further shown that there was a great preponderance of nitrogen in
the gases which the waters held in solution.
It must be remembered that, during the time when this geological work
was accomplished, Professor Rogers was an active teacher in the
University of Virginia, giving through a large part of the year almost
daily lectures either on physics or geology. Those who met him in his
after-life in various relations in Boston, and were often charmed by his
wonderful power of scientific exposition, can readily understand the
effect he must have produced, when in the prime of manhood, upon the
enthusiastic youths who were brought under his influence. His
lecture-room was always thronged. As one of his former students writes,
"All the aisles would be filled, and even the windows crowded from the
outside. In one instance I remember the crowd had assembled long before
the hour named for the lecture, and so filled the hall that the
professor could only gain admittance through a side entrance leading
from the rear of the hall through the apparatus-room. These facts show
how he was regarded by the students of the University of Virginia. His
manner of presenting the commonest subject in science--clothing his
thoughts, as he always did, with a marvelous fluency and clearness of
expression and beauty of diction--caused the warmest admiration, and
often aroused the excitable nature of Southern youths to the exhibition
of enthusiastic demonstrations of approbation. Throughout Virginia, and
indeed the entire South, his former students are scattered, who even now
regard it as one of the highest privileges of their lives to have
attended his lectures."
Such was the impression which Professor Rogers left at the University of
Virginia, that, when he returned, thirty-five years later, to aid in the
celebration of the semi-centennial, he was met with a perfect ovation.
Although the memories of the civil war, which had intervened, and
Professor Rogers's known sympathies with the Northern cause, might well
have damped enthusiasm, yet the presence of the highly honored teacher
was sufficient to rekindle the former admiration; and, in the language
of a contemporary Virginia newspaper, "the old students beheld before
them the same William B. Rogers who thirty-five years before had held
them spellbound in his class of natural philosophy; and, as the great
orator warmed up, these men forgot their age; they were again young, and
showed their enthusiasm as wildly as when, in days of yore, enraptured
by his eloquence, they made the lecture-room of the University ring with
their applause."
Besides his geological papers, Professor Rogers published, while at the
University of Virginia, a number of important chemical contributions,
relating chiefly to new and improved methods in chemical analysis and
research. These papers were published in connection with his youngest
brother, Robert E. Rogers, now become his colleague as Professor of
Chemistry and Materia Medica in the University; and such were the
singularly intimate relations between the brothers that it is often
impossible to dissociate their scientific work. Among these were papers
"On a New Process for obtaining Pure Chlorine"; "A New Process for
obtaining Formic Acid, Aldehyde, etc."; "On the Oxidation of the Diamond
in the Liquid Way"; "On New Instruments and Processes for the Analysis
of the Carbonates"; "On the Absorption of Carbonic Acid by Liquids";
besides the extended investigation "On the Decomposition of Minerals and
Rocks by Carbonated and Meteoric Waters," to which we have referred
above. There was also at this time a large amount of chemical work
constantly on hand in connection with the Geological Survey, such as
analyses of mineral waters, ores, and the like. Moreover, while at the
University of Virginia, Professor Rogers published a short treatise on
"The Strength of Materials," and a volume on "The Elements of
Mechanics,"--books which, though long out of print, were very useful
text-books in their day, and are marked by the clearness of style and
felicity of explanation for which the author was so distinguished.
The year 1853 formed a turning-point in Professor Rogers's life. Four
years previously he had married Miss Emma Savage, daughter of Hon. James
Savage, of Boston, the well-known author of the "New England
Genealogical Dictionary," and President of the Massachusetts Historical
Society. This connection proved to be the crowning blessing of his life.
Mrs. Rogers, by her energy, her intelligence, her cheerful equanimity,
her unfailing sympathy, became the promoter of his labors, the ornament
and solace of his middle life, and the devoted companion and support of
his declining years. Immediately after his marriage, June 20, 1849, he
visited Europe with his wife, and was present at the meeting of the
British Association for the Advancement of Science, held that year at
Birmingham, where he was received with great warmth, and made a most
marked impression. Returning home in the autumn, Professor Rogers
resumed his work at the University of Virginia; but the new family
relations which had been established led in 1853 to the transfer of his
residence to Boston, where a quite different, but even a more important,
sphere of usefulness surrounded him. His wide scientific reputation, as
well as his family connection, assured him a warm welcome in the most
cultivated circles of Boston society, where his strength of character,
his power of imparting knowledge, and his genial manners, soon commanded
universal respect and admiration. He at once took an active part in the
various scientific interests of the city. From 1845 he had been a Fellow
of this Academy;[J] and after taking up his residence among us he was a
frequent attendant at our meetings, often took part in our proceedings,
became a member of our Council, and from 1863 to 1869 acted as our
Corresponding Secretary. He took a similar interest in the Boston
Society of Natural History. He was a member, and for many years the
President, of the Thursday Evening Scientific Club, to which he imparted
new life and vigor, and which was rendered by him an important field of
influence. The members who were associated with him in that club will
never forget those masterly expositions of recent advances in physical
science; and will remember that, while he made clear their technical
importance to the wealthy business men around him, he never failed to
impress his auditors with the worth and dignity of scientific culture.
[J] This notice is reprinted from the Proceedings of the American
Academy of Arts and Sciences, vol. xviii, 1882-'83.
During the earlier years of his residence in Boston, Professor Rogers
occupied himself with a number of scientific problems, chiefly physical.
He studied the variations of ozone (or of what was then regarded as
ozone) in the atmosphere at the time when this subject was exciting
great attention. He was greatly interested in the improvements of the
Ruhmkorff Coil made by Mr. E. S. Ritchie; and in this connection
published a paper on the "Actinism of the Electric Discharge in Vacuum
Tubes." A study of the phenomena of binocular vision led to a paper
entitled "Experiments disproving by the Binocular Combination of Visual
Spectra Brewster's Theory of Successive Combinations of Corresponding
Points." A paper discussing the phenomena of smoke rings and rotating
rings in liquids appeared in the "American Journal of Science" for 1858,
with the description of a very simple but effective apparatus by which
the phenomena would be readily reproduced. In this paper Professor
Rogers anticipated some of the later results of Helmholtz and Sir
William Thomson. In the same year an ingenious illustration of the
properties of sonorous flames was exhibited to the Thursday Evening
Club above mentioned, in which Professor Rogers anticipated Count
Schafgottsch in the invention of a beautiful optical proof of the
discontinuity of the singing hydrogen flame.
In 1861 Professor Rogers accepted from Governor Andrew the office of
Inspector of Gas and Gas-Meters for the State of Massachusetts, and
organized a system of inspection in which he aimed to apply the latest
scientific knowledge to this work; and in a visit he again made to
Europe in 1864 he presented, at the meeting of the British Association
at Bath, a paper entitled "An Account of Apparatus and Processes for
Chemical and Photometrical Testing of Illuminating Gas."
During this period he gave several courses of lectures before the Lowell
Institute of Boston, which were listened to with the greatest
enthusiasm, and served very greatly to extend Professor Rogers's
reputation in this community. Night after night, crowded audiences,
consisting chiefly of teachers and working-people, were spellbound by
his wonderful power of exposition and illustration. There was a great
deal more in Professor Rogers's presentation of a subject than felicity
of expression, beauty of language, choice of epithets, or significance
of gesture. He had a power of marshaling facts, and bringing them all to
bear on the point he desired to illustrate, which rendered the
relations of his subject as clear as day. In listening to this powerful
oratory, one only felt that it might have had, if not a more useful,
still a more ambitious aim; for less power has moved senates and
determined the destinies of empires.
The interest in Professor Rogers's lectures was not excited solely,
however, by the charm of his eloquence; for, although such was the
felicity of his presentations, and such the vividness of his
descriptions, that he could often dispense with the material aids so
essential to most teachers, yet when the means of illustration were at
his command he showed his power quite as much in the adaptation of
experiments as in the choice of language. He well knew that experiments,
to be effective, must be simple and to the point; and he also knew how
to impress his audience with the beauty of the phenomena and with the
grandeur of the powers of nature. He always seemed to enjoy any elegant
or striking illustration of a physical principle even more than his
auditors, and it was delightful to see the enthusiasm which he felt over
the simplest phenomena of science when presented in a novel way.
We come now to the crowning and greatest work of Professor Rogers's
life, the founding of the Massachusetts Institute of Technology--an
achievement so important in its results, so far-reaching in its
prospects, and so complete in its details, that it overshadows all
else. A great preacher has said that "every man's life is a plan of
God's." The faithful workman can only make the best use of the
opportunities which every day offers; but he may be confident that work
faithfully done will not be for naught, and must trustingly leave the
issue to a higher power. Little did young Rogers think, when he began to
teach in Virginia, that he was to be the founder of a great institution
in the State of Massachusetts; and yet we can now see that the whole
work of his life was a preparation for this noble destiny. The very
eloquence he so early acquired was to be his great tool; his work on the
Geological Survey gave him a national reputation which was an essential
condition of success; his life at the University of Virginia, where he
was untrammeled by the traditions of the older universities, enabled him
to mature the practical methods of scientific teaching which were to
commend the future institution to a working community; and, most of all,
the force of character and large humanity developed by his varied
experience with the world were to give him the power, even in the
conservative State of his late adoption, to mold legislators and men of
affairs to his wise designs.
It would be out of place, as it would be unnecessary, to dwell in this
connection on the various stages in the development of the Institute of
Technology. The facts are very generally known in this community, and
the story has been already well told. The conception was by no means a
sudden inspiration, but was slowly matured out of a far more general and
less specific plan, originating in a committee of large-minded citizens
of Boston, who, in 1859, and again in 1860, petitioned the Legislature
of Massachusetts to set apart a small portion of the land reclaimed from
the Back Bay "for the use of such scientific, industrial, and fine art
institutions as may associate together for the public good." The large
scheme failed; but from the failure arose two institutions which are the
honor and pride of Boston--the Museum of Fine Arts and the Institute of
Technology. In the further development of the Museum of Fine Arts,
Professor Rogers had only a secondary influence; but one of his
memorials to the Legislature contains a most eloquent statement, often
quoted, of the value of the fine arts in education, which attests at
once the breadth of his culture and the largeness of his sympathies.
Although the committee of gentlemen above referred to had failed to
carry out their general plan, yet the discussions to which it gave rise
had developed such an interest in the establishment of an institution to
be devoted to industrial science and education that they determined upon
taking the preliminary steps toward the organization of such an
institution. A sub-committee was charged with preparing a plan; and the
result was a document, written by Professor Rogers, entitled "Objects
and Plan of an Institute of Technology." That document gave birth to the
Massachusetts Institute of Technology, for it enlisted sufficient
interest to authorize the committee to go forward. A charter with a
conditional grant of land was obtained from the Legislature in 1861, and
the institution was definitely organized, and Professor Rogers appointed
President, April 8, 1862. Still, the final plans were not matured, and
it was not until May 30, 1864, that the government of the new
institution adopted the report prepared by its president, entitled
"Scope and Plan of the School of Industrial Science of the Massachusetts
Institute of Technology," which Dr. Runkle has called the "intellectual
charter" of the institution, and which he states "has been followed in
all essential points to this very day." In striking confirmation of what
we have written above, Dr. Runkle further says:
"In this document we see more clearly the breadth, depth, and variety of
Professor Rogers's scientific knowledge, and his large experience in
college teaching and discipline. It needed just this combination of
acquirements and experience to put his conceptions into working shape,
to group together those studies and exercises which naturally and
properly belong to each professional course, and thus enable others to
see the guiding-lines which must direct and limit their work in its
relations to the demands of other departments....
"The experimental element in our school--a feature which has been widely
recognized as characteristic--is undoubtedly due to the stress and
distinctness given to it in the 'Scope and Plan.' In our discipline we
must also give credit to the tact and large-heartedness of Professor
Rogers--in the fact that we are entirely free from all petty rules and
regulations relating to conduct, free from all antagonism between
teachers and students."
The associates of Professor Rogers in this Academy--many of them his
associates also in the Institute of Technology, or in the Society of
Arts, which was so important a feature of the organization--will
remember with what admiration they watched the indefatigable care with
which its ever active president fostered the young life of the
institution he had created. They know how, during the earlier years, he
bore the whole weight of the responsibility of the trust he had
voluntarily and unselfishly assumed for the public good; how, while by
his personal influence obtaining means for the daily support of the
school, he gave a great part of the instruction, and extended a personal
regard to every individual student committed to his charge. They recall
with what wisdom, skill, tact, and patience he directed the increasing
means and expanding scope of the now vigorous institution, overcoming
obstacles, reconciling differences, and ingratiating public favor. They
will never forget how, when the great depression succeeded the unhealthy
business activity caused by the civil war, during which the institution
had its rise, the powerful influence of its great leader was able to
conduct it safely through the financial storm. They greatly grieved
when, in the autumn of 1868, the great man who had accomplished so much,
but on whom so much depended, his nerves fatigued by care and overwork,
was obliged to transfer the leadership to a younger man; and ten years
later were correspondingly rejoiced to see the honored chief come again
to the front, with his mental power unimpaired, and with adequate
strength to use his well-earned influence to secure those endowments
which the increased life of the institution required; and they rejoiced
with him when he was able to transfer to a worthy successor the
completed edifice, well established and equipped--an enduring monument
to the nobility of character and the consecration of talents. They have
been present also on that last occasion, and have united in the
acclamation which bestowed on him the title "Founder and Father
perpetual, by a patent indefeasible." They have heard his feeling but
modest response, and have been rejoicing though tearful witnesses when,
after the final seal of commendation was set, he fell back, and the
great work was done.
We honor the successful teacher, we honor the investigator of Nature's
laws, we honor the upright director of affairs--and our late associate
had all these claims to our regard; but we honor most of all the noble
manhood--and of such make are the founders of great institutions. In
comparison, how empty are the ordinary titles of distinction of which
most men are proud! It seems now almost trivial to add that our
associate was decorated with a Doctor's degree, both by his own
university and also by the University at Cambridge; that he was sought
as a member by many learned societies; that he was twice called to
preside over the annual meetings of the American Association for the
Advancement of Science; and that, at the death of Professor Henry, he
was the one man of the country to whom all pointed as the President of
the National Academy of Science. This last honor, however, was one on
which it is a satisfaction to dwell for a moment, because it gave
satisfaction to Professor Rogers, and the office was one which he
greatly adorned, and for which his unusual oratorical abilities were so
well suited. He was a most admirable presiding officer of a learned
society. His breadth of soul and urbanity of manner insensibly resolved
the discords which often disturb the harmonies of scientific truth. He
had the delicate tact so to introduce a speaker as to win in advance the
attention of the audience, without intruding his own personality; and
when a paper was read, and the discussion closed, he would sum up the
argument with such clearness, and throw around the subject such a glow
of light, that abstruse results of scientific investigation were made
clear to the general comprehension, and a recognition gained for the
author which the shrinking investigator could never have secured for
himself. To Professor Rogers the truth was always beautiful, and he
could make it radiant.
It is also a pleasure to record, in conclusion, that Professor Rogers's
declining years were passed in great comfort and tranquillity, amidst
all the amenities of life; that to the last he had the companionship of
her whom he so greatly loved; and that increasing infirmities were
guarded and the accidents of age warded off with a watchfulness that
only the tenderest love can keep. We delight to remember him in that
pleasant summer home at Newport, which he made so fully in reality as in
name the "Morning-side," that we never thought of him as old, and to
believe that the morning glow which he so often watched spreading above
the eastern ocean was the promise of the fuller day on which he has
entered.
