Humboldt--Alexander Von Humboldt, as he always called himself, though he

was christened with the names of Frederick Heinrich Alexander--was born

in 1769, on September 14th, in that memorable year which gave to the

world those philosophers, warriors, and statesmen who have changed the

face of science and the condition of affairs in our century. It was in

that year that Cuvier also and Schiller were born; and among the

warriors and statesmen, Napoleon, the Duke of Wellington, and Canning

are children of 1769, and it is certainly a year of which we can say

that its children have revolutionized the world. Of the early life of

Humboldt I know nothing, and I find no records except that in his tenth

year he lost his father, who had been a major in the army during the

seven years' war, and afterward a chamberlain to the King of Prussia.

But his mother took excellent care of him, and watched over his early

education. The influence she had upon his life is evident from the fact

that, notwithstanding his yearning for the sight of foreign lands, he

did not begin to make active preparations for his travels during her

lifetime. In the winter of 1787-1788 he was sent to the University of

Frankfort on the Oder, to study finances. He was to be a statesman; he

was to enter high offices, for which there was a fair chance, owing to

his noble birth and the patronage he could expect at court. He remained,

however, but a short time there.

Not finding these studies to his taste, after a semestre's residence in

the university we find him again at Berlin, and there in intimate

friendship with Wildenow, then professor of botany, and who at that time

possessed the greatest herbarium in existence. Botany was the first

branch of natural science to which Humboldt paid especial attention. The

next year he went to Goettingen--being then a youth of twenty years; and

here he studied natural history with Blumenbach, and thus had an

opportunity of seeing the progress zooelogy was making in anticipation of

the great movement by which Cuvier placed zooelogy on a new foundation.

For it is an unquestionable fact that in first presenting a

classification of the animal kingdom based upon a knowledge of its

structure, Blumenbach in a measure anticipated Cuvier; though it is

only by an exaggeration of what Blumenbach did that an unfair writer of

later times has attempted to deprive Cuvier of the glory of having

accomplished this object upon the broadest possible basis. From

Goettingen he visited the Rhine, for the purpose of studying geology, and

in particular the basaltic formations of the Seven Mountains. At Mayence

he became acquainted with George Forster, who proposed to accompany him

on a journey to England. You may imagine what impression the

conversation of that active, impetuous and powerful man had upon the

youthful Humboldt. They went to Belgium and Holland, and thence to

England, where Forster introduced him to Sir Joseph Banks. Thus the

companions of Captain Cook in his first and second voyages round the

world, who were already venerable in years and eminent promoters of

physical science not yet established in the popular favor, were the

early guides of Humboldt in his aspirations for scientific distinction.

Yet Humboldt had a worldly career to accomplish. He was to be a

statesman, and this required that he should go to the Academy of

Commerce at Hamburg. He remained there five months, but could endure it

no longer, and he begged so hard that his mother allowed him to go to

Freyberg and study geology with Werner, with a view of obtaining a

situation in the Administration of Mines. See what combinations of

circumstances prepare him for his great career, as no other young man

ever was prepared. At Freyberg he received the private instruction of

Werner, the founder of modern geology, and he had as his fellow-student

no less a man than Leopold Von Buch, then a youth, to whom, at a later

period, Humboldt himself dedicated one of his works, inscribing it "to

the greatest geologist," as he was till the day of his recent death.

From Freyberg he made frequent excursions into the Hartz and

Fichtelgeberg and surrounding regions, and these excursions ended in the

publication of a small work upon the subterranean flora of Freyberg

("Flora Subterranea Fribergensis"), in which he described especially

those cryptogamous plants, or singular low and imperfect formations

which occur in the deep mines. But here ends his period of pupilage. In

1792 he was appointed an officer of the mines (Oberbergmeister). He went

to Beyreuth as director of the operations in those mines belonging to

the Frankish provinces of Prussia. Yet he was always wandering in every

direction, seeking for information and new subjects of study. He visited

Vienna, and there heard of the discoveries of Galvani, with which he

made himself familiar; went to Italy and Switzerland, where he became

acquainted with the then celebrated Professors Jurine and Pictet, and

with the illustrious Scarpa. He also went to Jena, formed an intimate

acquaintance with Schiller and Goethe, and also with Loder, with whom he

studied anatomy. From that time he began to make investigations of his

own, and these investigations were in a line which he has never

approached since, being experiments in physiology. He turned his

attention to the newly-discovered power by which he tested the activity

of organic substances; and it is plain, from his manner of treating the

subject, that he leaned to the idea that the chemical process going on

in the living body of animals furnished a clew to the phenomena of life,

if it was not life itself. This may be inferred from the title of the

book published in 1797--"Ueber die gereizte Muskel und Nervenfaser, mit

Vermuthungen ueber den chemischen Process des Lebens, in Thieren und

Pflanzen."

In these explanations of the phenomena we have the sources of the first

impulses in a direction which has been so beneficial in advancing the

true explanation of the secondary phenomena of life; but which, at the

same time, in its exaggeration as it prevails now has degenerated into

the materialism of modern investigators.

In that period of all-embracing activity, he began to study astronomy.

His attention was called to it by Baron Von Zach, who was a prominent

astronomer of the time, and who at that time was actively engaged upon

astronomical investigations in Germany. He showed Humboldt to what

extent astronomy would be useful to him, in his travels, in determining

the position of places, the altitude of mountains, etc.

So prepared, Humboldt now broods over his plans of foreign travel. He

has published his work on the muscular and nervous fibre at the age of

twenty-eight. He has lost his mother; and his mind is now inflamed with

an ungovernable passion for the sight of foreign and especially tropical

lands. He goes to Paris to make preparation by securing the best

astronomical, meteorological and surveying instruments. Evidently he

does not care where he shall go, for on a proposition of Lord Bristol to

visit Egypt he agrees to it. The war prevents the execution of this

plan, and he enters into negotiations to accompany the projected

expedition of Captain Baudin to Australia; but when Bonaparte, bent on

the conquest of Egypt, started with a scientific expedition, Humboldt

wishes to join it. He expects to be one of the scientific party, and to

reach Egypt by way of Barbary.

But all these plans failing, he goes to Spain with the view of exploring

that country, and finding perhaps some means of joining the French

expedition in Egypt from Spain. While in Madrid he is so well received

at the court--a young nobleman so well instructed has access

everywhere--and he receives such encouragement from persons in high

positions, that he turns his thoughts to an exploration of the Spanish

provinces of America. He receives permission not only to visit them, but

instructions are given to the officers of the colonies to receive him

everywhere and give him all facilities, to permit him to transport his

instruments, to make astronomical and other observations, and to collect

whatever he chooses; and all that only in consequence of the good

impression he has made when he appeared there, with no other

recommendation than that of a friend who happened to be at that time

Danish minister to the court of Madrid. But with these facilities

offered to him, he sails in June, 1799, from Corunna, whence he reaches

Teneriffe, makes short explorations of that island, ascending the peak,

and sailing straightway to America, where he lands in Cumana in the

month of July, and employs the first year and a half in the exploration

of the basin of the Orinoco and its connection with the Amazon. This was

a journey of itself, and completed a work of scientific importance,

establishing the fact that the two rivers were connected by an

uninterrupted course of water. He established for the first time the

fact that there was an extensive low plain, connected by water, which

circled the high table-land of Guiana. It was an important discovery in

physical geography, because it changed the ideas about water-courses and

about the distributions of mountains and plains in a manner which has

had the most extensive influence upon the progress of physical

geography. It may well be said that after this exploration of the

Orinoco, physical geography begins to appear as a part of science. From

Cumana he makes a short excursion to Havana, and hearing there of the

probable arrival of Baudin on the west coast of America, starts with the

intention of crossing at Panama. He arrives at Carthagena, but was

prevented by the advance of the season from crossing the Isthmus, and

changed his determination from want of precise information respecting

Baudin's locality. He determines to ascend the Magdalena River and visit

Santa Fe de Bogota, where, for several months, he explores the

construction of the mountains, and collects plants and animals; and, in

connection with his friend, Bonpland, who accompanied him from Paris, he

makes those immense botanical collections, which were afterward

published by Bonpland himself, and by Kunth after Bonpland had

determined on an expedition to South America. In the beginning of 1802

he reaches Quito, where, during four months, he turns his attention to

everything worth investigating, ascends the Chimborazo, to a height to

which no human foot had reached, anywhere; and, having completed this

survey and repeatedly crossed the Andes, he descends the southern slope

of the continent to the shore of the Pacific at Truxillo, and following

the arid coast of Peru, he visits finally Lima.

I will pass lightly over all the details of his journey, for they are

only incidents in that laborious exploration of the country which is

best appreciated by a consideration of the works which were published in

consequence of that immense accumulation of materials gathered during

those explorations. From Lima, or rather from Callao, he sails in 1802

for Guayaquil and Acapulco, and reaches Mexico in 1803, where he makes

as extensive explorations as he had made in Venezuela and the Andes, and

after a stay of about a year, and having put all his collections and

manuscripts in order, revisits Cuba for a short time, comes to the

United States, makes a hurried excursion to Philadelphia and Washington,

where he is welcomed by Jefferson, and finally returns with his faithful

companion Bonpland to France, accompanied by a young Spanish nobleman,

Don Carlo de Montufar, who had shared his travels since his visits to

Quito.

At thirty-six years of age Humboldt is again in Europe with collections

made in foreign lands, such as had never been brought together before.

But here we meet with a singular circumstance. The German nobleman, the

friend of the Prussian and Spanish courts, chooses Paris for his

residence, and remains there twenty-two years to work out the result of

his scientific labor; for since his return, with the exception of short

journeys to Italy, England and Germany, sometimes accompanying the King

of Prussia, sometimes alone, or accompanied by scientific friends, he is

entirely occupied in scientific labors and studies. So passes the time

to the year 1827, and no doubt he was induced to make this choice of a

residence by the extraordinary concourse of distinguished men in all

branches of science with whom he thought he could best discuss the

results of his own observations. I shall presently have something to say

about the works he completed during that most laborious period of his

life. I will only add now, that in 1827 he returned to Berlin

permanently, having been urged of late by the King of Prussia again and

again to return to his native land. And there he delivered a series of

lectures preparatory to the publication of "Cosmos;" for in substance,

even in form and arrangement, these lectures, of which the papers of the

day gave short accounts, are a sort of prologue to the "Cosmos," and a

preparation for its publication. In 1829, when he was sixty years of

age, he undertakes another great journey. He accepts the invitation of

the Emperor Nicholas to visit the Ural Mountains, with a view of

examining the gold mines, and localities where platina and diamonds had

been found, to determine their geological relation. He accomplished the

journey with Ehrenberg and Gustavus Rose, who published the result of

their mineralogical and geological survey, in a work of which he is the

sole author; while Humboldt published under the title of "Asiatic

Fragments of Geology and Climatology," his observations of the physical

and geographical features made during that journey. But he had hardly

returned to Berlin when in consequence of the revolution of 1830, he was

sent by the King of Prussia as extraordinary ambassador to France, to

honor the elevation of Louis Philippe to the throne. Humboldt had long

been a personal friend of the Orleans family, and he was selected

ambassador on that occasion on account of these personal relations. From

1830 to 1848 he lived alternately in Berlin and in Paris, spending

nearly half the time in Paris and half the time in Berlin, with

occasional visits to England and Denmark; publishing the results of his

investigations in Asia, making original investigations upon various

things and especially pressing the establishment of observatories, and

connected magnetic observations all over the globe, for which he

obtained the co-operation of the Russian government and that of the

government of England; and at that time those observations in Australia

and in the Russian empire to the borders of China, were established

which have led to such important results in our knowledge of terrestrial

magnetism. Since 1848 he has lived uninterruptedly in Berlin, where he

published on the anniversary of his eightieth year a new edition of

those charming first flowers of his pen; his "Views of Nature," the

first edition of which was published in Germany in 1808. This third

edition appeared with a series of new and remodelled annotations and

explanations; and that book in which he first presented his views of

nature, in which he drew those vivid pictures of the physiognomy of

plants and of their geographical distribution is now revived and brought

to the present state of science.

The "Views of Nature" is a work which Humboldt has always cherished, and

to which in his "Cosmos" he refers more frequently than to any other

work. It is no doubt because there he has expressed his deepest

thoughts, his most impressive views, and even foreshadowed those

intimate convictions which he never expressed, but which he desired to

record in such a manner that those that can read between the lines might

find them there; and certainly there we find them. His aspiration has

been to present to the world a picture of the physical world from which

he would exclude everything that relates to the turmoil of human

society, and to the ambitions of individual men. A life so full, so

rich, is worth explaining in every respect, and it is really instructive

to see with what devotion he pursues his work. As long as he is a

student he is really a student and learns faithfully, and learns

everything he can reach. And he continues so for twenty-three years. He

is not one of those who is impatient to show that he has something in

him, and with premature impatience utters his ideas, so that they become

insuperable barriers to his independent progress in later life. Slowly

and confident of his sure progress, he advances, and while he learns he

studies also independently of those who teach him. He makes his

experiments, and to make them with more independence he seeks for an

official position. During five years he is a business man, in a station

which gives him leisure. He is superintendent of the mines, but the

superintendent of the mines who can do much as he pleases; and while he

is thus officially engaged journeying and superintending, he prepares

himself for his independent researches. And yet it will be seen he is

thirty years of age before he enters upon his American travels--those

travels which will be said to have been the greatest undertaking ever

carried to a successful issue, if judged by the results; they have as

completely changed the basis of physical science as the revolution which

took place in France about the same time has changed the social

condition of that land. Having returned from these travels to Paris,

there begins in his life a period of concentrated critical studies. He

works his materials, and he works them with an ardor and devotion which

are untiring; and he is not anxious to appear to have done it all

himself. Oltmann is called to his aid to revise his astronomical

observations, and his barometrical measurements by which he has

determined the geographical position of seven hundred different points

and the altitude of more than four hundred and fifty of them.

The large collection of plants which Bonpland had begun to illustrate,

but of which his desire of seeing the tropics again has prevented the

completion he intrusts to Kunth. He has also brought home animals of

different classes, and distributes them among the most eminent

zooelogists of the day.

To Cuvier he intrusts the investigation of that remarkable batrachian,

the Aaeolotel, the mode of development of which is still unknown, but

which remains in its adult state in a condition similar to that of the

tadpole of the frog during the earlier period of its life. Latreille

describes the insects, and Valenciennes the shells and the fishes; but

yet to show that he might have done the work himself, he publishes a

memoir on the anatomical structure of the organs of breathing in the

animals he has preserved, and another upon the tropical monkeys of

America, and another upon the electric properties of the electric eel.

But he was chiefly occupied with investigations in physical geography

and climatology. The first work upon that subject is a dissertation on

the geographical distribution of plants, published in 1817. Many

botanist travellers had observed that in different parts of the world

there are plants not found in others, and that there is a certain

arrangement in that distribution; but Humboldt was the first to see that

this distribution is connected with the temperature of the air as well

as with the altitudes of the surface on which they grow, and he

systematized his researches into a general exposition of the laws by

which the distribution of plants is regulated. Connected with this

subject he made those extensive investigations into the mean temperature

of a large number of places on the surface of the globe, which led to

the drawing of those isothermal lines so important in their influence in

shaping physical geography, and giving accuracy to the mode of

representing natural phenomena. Before Humboldt we had no graphic

representation of complex natural phenomena which made them easily

comprehensible, even to minds of moderate cultivation. He has done that

in a way which has circulated information more extensively, and brought

it to the apprehension more clearly than it could have been done by any

other means.

It is not too much to say that this mode of representing natural

phenomena has made it possible to introduce in our most elementary works

the broad generalizations derived from the investigations of Humboldt in

South America; and that every child in our schools has his mind fed from

the labors of Humboldt's brain, wherever geography is no longer taught

in the old routine.

* * * * *

Humboldt was born near the court. He was brought up in connection with

courtiers and men in high positions of life. He was no doubt imbued with

the prejudices of his caste. He was a nobleman of high descent. And yet

the friend of kings was the bosom friend of Arago, and he was the man

who could, after his return from America, refuse the highest position at

the court of Berlin, that of the secretaryship of public instruction,

preferring to live in a modest way in Paris, in the society of all those

illustrious men, who then made Paris the centre of intellectual culture.

It was there where he became one of that Societe d'Arceuil, composed of

all the great men of the day, to which the paper on "Isothermal Lines"

was presented, and by which it was printed, as all papers presented to

it were, for private distribution. But from his intimate relations,

especially to the court of Prussia, some insinuations have been made as

to the character of Humboldt. They are as unjust as they are severe in

expression. He was never a flatterer of those in power. He has shown it

by taking a prominent position, in 1848, at the head of those who

accompanied the victims of the revolution of that year to their last

place of rest. But while he expressed his independence in such a manner,

he had the kindliest feeling for all parties. He could not offend, even

by an expression, those with whom he had been associated in early life;

and I have no doubt that it is to that kindliness of feeling we must

ascribe his somewhat indiscriminate patronage of aspirants in science,

as well as men who were truly devoted to its highest aims. He may be

said to have been, especially in his latter years, the friend of every

cultivated man, wishing to lose no opportunity to do all the good of

which he was capable; for he had a degree of benevolence and generosity

which was unbounded. I can well say that there is not a man engaged in

scientific investigations in Europe, who has not received at his hands

marked tokens of his favor, and who is not under deep obligations to

him. May I be permitted to tell a circumstance which is personal to me

in that respect, and which shows what he was capable of doing while he

was forbidden an opportunity of telling it. I was only twenty-four years

of age when in Paris, whither I had gone with means given me by a

friend; but was at last about to resign my studies from want of ability

to meet my expenses. Professor Mitscherlich was then on a visit to

Paris, and I had seen him in the morning, when he asked me what was the

cause of my depressed feelings; and I told him that I had to go for I

had nothing left. The next morning as I was seated at breakfast in front

of the yard of the hotel where I lived, I saw the servant of Humboldt

approach. He handed me a note, saying there was no answer and

disappeared. I opened the note, and I see it now before me as distinctly

as if I held the paper in my hand. It said:--

"My friend, I hear that you intend leaving Paris in consequence of some

embarrassments. That shall not be. I wish you to remain here as long as

the object for which you came is not accomplished. I enclose you a check

of L50. It is a loan which you may repay when you can."

Some years afterward, when I could have repaid him, I wrote, asking for

the privilege of remaining forever in his debt, knowing that this

request would be more consonant to his feelings than the recovery of the

money, and I am now in his debt. What he has done for me, I know he has

done for many others; in silence and unknown to the world. I wish I

could go on to state something of his character, his conversational

powers, etc., but I feel that I am not in a condition to speak of them.

I would only say that his habits were very peculiar. He was an early

riser, and yet he was seen at late hours in the salons in different

parts of Paris. From the year 1830 to 1848, while in Paris, he had been

charged by the King of Prussia to send reports upon the condition of

things there. He had before prepared for the King of Prussia a report on

the political condition of the Spanish colonies in America, which no

doubt had its influence afterward upon the recognition of the

independence of those colonies. The importance of such reports to the

government of Prussia may be inferred from a perusal of his political

and statistical essays upon Mexico and Cuba. It is a circumstance worth

noticing, that above all great powers, Prussia has more distinguished,

scientific, and literary men among her diplomatists than any other

state. And so was Humboldt actually a diplomatist in Paris, though he

was placed in that position, not from choice, but in consequence of the

benevolence of the king, who wanted to give him an opportunity of being

in Paris as often and as long as he chose.

But from that time there were two men in him--the diplomatist, living in

the Hotel des Princes, and the naturalist who roomed in the Rue de la

Harpe, in a modest apartment in the second story; where his scientific

friends had access to him every day before seven. After that he was

frequently seen working in the library of the Institute, until the time

when the grand seigneur made his appearance at the court or in the

salons of Paris.

The influence he has exerted upon the progress of science is

incalculable. I need only allude to the fact that the "Cosmos," bringing

every branch of natural science down to the comprehension of every class

of students, has been translated into the language of every civilized

nation of the world, and gone through several editions. With him ends a

great period in the history of science, a period to which Cuvier,

Laplace, Arago, Gay-Lussac and De Candolle, and Robert Brown belonged.
