Charles Henry Turner

Born: 1867
Birthplace: Cincinnati, Ohio

Although he held a doctorate from the University of Chicago, zoologist Charles Henry Turner chose to teach at high schools so he could devote more time to the observation of insects. His research had lasting impact. Turner published several articles in scientific journals, including "Habits of Mound-Building Ants," "Experiments on the Color Vision of the Honeybee," "Hunting Habits of an American Sand Wasp," and "Psychological Notes on the Gallery Spider." In his research, Turner became the first person to prove that insects can hear and can distinguish pitch. In addition, he first discovered that cockroaches can learn by trial and error.
