John Call Dalton was an American physiologist, the first full-time professor for physiology in the United States.
Background
John Call Dalton was born on February 2, 1825 in Chelmsford, Massachusetts, United States. He was the son of Dr. John Call Dalton and Julia Ann (Spalding), the former a representative of a notable medical ancestry, he was apparently predestined for the medical profession.
Education
Graduating from Harvard College in 1844 and from the Harvard Medical School in 1847, Dalton went to Paris where he came under the influence of the renowned physiologist, Claude Bernard, and was at once impressed with the great value of experimental work in medicine, particularly in physiology.
From 1851 to 1854 he was professor of physiology at the University of Buffalo; 1854-56 at the University of Vermont; 1855-83 at the College of Physicians and Surgeons, New York.
Career
Dalton put aside all thought of medical practise, and began his work as a teacher, opening a new era in the teaching of physiology in America.
Before his time the didactic lecture and the textbook were the sole methods of instruction; he introduced the experimental method, illustrating the processes of life with living animals, which the action of ether, just then discovered, made it possible to do without pain.
From 1851 to 1854 he was professor of physiology at the University of Buffalo; 1854-56 at the University of Vermont; 1855-83 at the College of Physicians and Surgeons, New York.
From 1859 to 1861 he was also connected with the Long Island College Hospital.
During the period of the Civil War he served as surgeon in the medical corps of the volunteer army, with the rank of brigadier-general.
Such work, however, was not congenial to him; he was better fitted for the experimentation of the laboratory, where, with his logical mind and skilful manipulation, he made clear the functioning of the vital mechanisms of the body.
His writings were notable because what he wrote was based largely upon what he had actually seen experimentally. They included a Treatise on Human Physiology issued in 1859, which in 1882 had reached the seventh edition; A Treatise on Physiology and Hygiene (1868); Experimentation on Animals as a Means of Knowledge in Physiology, Pathology, and Practical Medicine (1875); The Experimental Method in Medical Science (1882); Doctrines of the Circidation (1884). Especially noteworthy was his morphological work, Topographical Anatomy of the Brain (1885), for which it is said he prepared with his own hands all the specimens, photographs of which made up a large part of the book.
For years he had to fight against interference by individuals and societies of anti-vivisectionists, who with misdirected zeal sought by legislative action to prevent all experimentation upon living animals, but with his firm conviction of the value to humanity of the knowledge to be gained by such methods of experimentation he used all his powers to contest these efforts and to lead the public to a better understanding of the matter.
During the later years of his life he served (1884 - 89) as president of the College of Physicians and Surgeons, bringing to that office his great breadth of knowledge and critical judgment, combined with administrative powers of a high order which were freely used for the advancement of the college.
In the last year of his life he wrote down for his family some reminiscences of his Civil War service. These, still uncompleted, were privately printed in 1892 under the title, John Call Dalton, M. D. , U. S. V.
He was a member of many national and European societies and in 1864 was elected a member of the National Academy of Sciences.
Personality
Dalton lived a simple, unpretentious life, a bachelor, a quiet scholar, devoted to his studies; a deep thinker whose greatest happiness was found in his study and in the laboratory.
He dedicated his entire life to his profession. Psycology was a real passion for him and it was occupying him mind until the end of his life.
