Samuel Drake Lockwood was an American zoologist, teacher, and historian of the development of biological science.
Background
Samuel Drake Lockwood came of Dutch ancestry, his forefathers having emigrated from Holland in 1651. Born on September 14, 1857 at Troy, Michigan, United States, the son of Lorenzo Dow and Sarah (Kingsbury) Locy, he grew up in a home that provided education in music, science, and the humanities. His father was a dentist.
Education
Locy received the degree of Bachelor of Science from the University of Michigan in 1881. He continued his studies in biology there during 1881-1882 and received the degree of Master of Science in 1884. He received his degree of Doctor of Philosophy in 1895.
Career
During 1884-1885, under a fellowship at Harvard University, Locy completed a noteworthy embryological investigation on the development of Agelena naevia (a spider), in the laboratory of Prof. Edward Laurens Mark. The year 1891 he spent at the University of Berlin. Under an honorary fellowship at the University of Chicago in 1894, he prosecuted studies upon the structure and development of the vertebrate head, in the laboratories of Prof. Charles O. Whitman, producing a thesis on this subject. For several summers Locy was occupied in research at the Marine Biological Laboratories at Woods Hole, Massachusetts. After an experience of three years' teaching in secondary schools, in 1887 he became professor of biology in Lake Forest University, Illinois, his title being changed in 1889 to professor of animal morphology. While at Lake Forest he also served one year as professor of physiology at the Rush Medical College, Chicago.
In January 1896 he went to Northwestern University, Evanston, Illinois, as professor of zoology and director of the zoological laboratories, in which capacity he remained for twenty-eight years. "His study of the embryonic neuromeres of the fore and mid-brain of fishes stands in the fore-front of investigation on neurai metamerism"; while "his study of the nervus terminalis (accessory cranial nerve) in Elasmobranchs was so thorough as to dominate and become the standard for all later investigations". Other highly valued papers concern the embryonic development of elasmobranchs (sharks), and the derivation of the pineal eye.
During the later years of his career he gave his attention more and more to developing a general interest in the early history of the sciences of biology and medicine, and his devotion to this field of research is marked by a series of brief, valuable, historical, non-technical papers; among them, Malpighi, Swammerdam and Leeuwenhoek (1901); "Service of Zoology to Intellectual Progress" (Popular Science, October 1909); "Earliest Printed Illustrations of Natural History"; "Wilhelm Hofmeister".
In 1911 appeared a more extended paper upon "Anatomical Illustrations Before Vesalius" covering forty-four pages, with twenty-three figures, and appearing in the Whitman memorial number of the Journal of Morphology (December 1911). The final outcome of his zeal in the study of the historical development of biology took the form of three books: Biology and Its Makers; The Main Currents of Zoology (1918); and, his last work, completed a few days before his death, Growth of Biology (1925). He was editor in charge of zoological articles for the New American Supplement to the Encyclopaedia Britannica (5 vols. , 1897), writing several of them himself.
Achievements
During his tenure as professor of zoology and director of the zoological laboratories at Northwestern University, fifty-four advanced degrees were given by the university for work done under his direction and supervision. Locy produced no less than fifty-six scientific papers, some of which are regarded as landmarks in their fields.
