Charles Otis Whitman (December 6, 1842 – December 14, 1910) was an American zoologist, who was influential to the founding of classical ethology. A dedicated educator who preferred to teach a few research students at a time, he made major contributions in the areas of evolution and embryology of worms, comparative anatomy, heredity, and animal behaviour. He was known as the "Father of Zoology" in Japan.
Whitman was born in Woodstock, Maine. His parents were Adventist pacifists and prevented his efforts to enlist in the Union army in 1862. He worked as a part-time teacher, and converted to Unitarianism. He graduated from Bowdoin College in 1868. Following graduation Whitman became principal of the Westford Academy, a small Unitarian-oriented college preparatory school outside Lowell, Massachusetts. In 1872 he moved to Boston and after becoming a member of the Boston Society of Natural History in 1874, he decided to study zoology full-time. In 1875 he took a leave of absence and went to the University of Leipzig in Germany to complete a Ph.D. which he obtained in 1878.
A year later he received a postdoctoral fellowship at the Johns Hopkins University, but immediately gave it up when after recommended by noted biologist Edward Sylvester Morse, he was hired by the Japanese government to succeed Morse as professor at the Tokyo Imperial University from 1879-1881. Influenced by his training in Germany, he introduced systematic methods of biological research, including the use of the microscope.
After leaving Japan, Whitman performed research at the Naples Zoological Station (1882), became an assistant at the Museum of Comparative Zoology, Harvard University (1883–5), then directed the Allis Lake Laboratory, in Milwaukee (1886–9), where he founded the Journal of Morphology (1887).
In 1884, Whitman married Emily Nunn. He moved to Clark University (Worcester, Massachusetts) (1889–92), then became a professor and curator of the Zoological Museum at the University of Chicago (1892–1910), while concurrently serving as founding director of the Marine Biological Laboratory, Woods Hole, Massachusetts (1888–1908). During the 1880s, Whitman established himself as the central figure of academic biology in the United States. He systematized the procedures that European anatomists and zoologists had gradually developed ever the past two decades.
Over the course of his career, Whitman worked with more than 700 species of pigeons, studying the relationship between phenotypic variation and heredity. By the turn of the 20th century, the last group of passenger pigeons, all descended from the same pair, was kept by Whitman at the University of Chicago. The last attempt to breed the remaining specimens was done by Whitman and the Cincinnati Zoo, which included attempts at making a rock dove foster Passenger Pigeon eggs. Whitman sent Martha, which was to be the last known specimen, to Cincinnati Zoo in 1902.
In December 1910, however, he caught a chill, and died a few days later.
Whitman was a non-Darwinian evolutionist. Stephen Jay Gould wrote that Whitman did not believe in Lamarckism, Darwinism or mutationism, instead Whitman was an advocate of orthogenesis. Whitman only wrote one book on orthogenesis which was published nine years after his death in 1919 titled Orthogenetic evolution in pigeons the book was published in a three volume set titled Posthumous Works of Charles Otis Whitman, Gould claims that the book was written "too late, to win any potential influence".
