JOHN WILLIAM DRAPER

(1811-1882)

[Illustration: JOHN WILLIAM DRAPER]

The subject of this sketch was born at St. Helen's, near Liverpool,

England, on the 5th of May, 1811. His earliest education was obtained

at a Wesleyan Methodist school, but after a time he came under private

teachers, with whose help he made rapid progress in the physical

sciences, thus showing in his boyhood the natural bent of his mind and

the real strength of his intellect. He afterwards studied for a time

at the University of London, but in 1833 came to the United States,

and three years later graduated at the University of Pennsylvania with

the degree of M. D. In 1839 he was elected to the chair of chemistry

in the University of New York, a position which he held until his

death in 1882.

Draper's contributions to science were of a high order. He discovered

some of the facts that lie at the basis of spectrum analysis; he was

one of the first successful experimenters in the art of photography;

and he made researches in radiant energy and other scientific

phenomena. He published in 1858 a treatise on 'Human Physiology,'

which is a highly esteemed and widely used text-book. He died on the

4th of January, 1882.

Draper's chief contributions to literature are three works: 'History

of the Intellectual Development of Europe' (1863), a 'History of the

American Civil War' (1867-1870), and 'The History of the Conflict

between Religion and Science,' which appeared in the International

Scientific Series in 1873. Of these works, the one on the intellectual

development of Europe is the ablest, and takes a place beside the

works of Lecky and Buckle as a contribution to the history of

civilization. The history of the Civil War was written too soon after

the events described to have permanent historical value. 'The History

of the Conflict between Religion and Science' is a judicial

presentation of the perennial controversy from the standpoint of the

scientist.

Draper's claims to attention as a philosophic historian rest mainly on

his theory of the influence of climate on human character and

development. He maintains that "For every climate, and indeed for

every geographical locality, there is an answering type of humanity";

and in his history of the American Civil War, as well as in his work

on the intellectual development of Europe, he endeavored to prove that

doctrine. Another theory which is prominent in his principal work is,

that the intellectual development of every people passes through five

stages; namely, 1, the Age of Credulity; 2, the Age of Inquiry; 3, the

Age of Faith; 4, the Age of Reason; 5, the Age of Decrepitude. Ancient

Greece, he thinks, passed through all those stages, the age of reason

beginning with the advent of physical science. Europe as a whole has

now also entered the age of reason, which as before he identifies with

the age of physical science; so that everywhere in his historical

works, physical influences and the scientific knowledge of physical

phenomena are credited with most of the progress that mankind has

made. Draper has left a distinct mark upon the scientific thought of

his generation, and made a distinct and valuable contribution to the

literature of his adopted country.
