This unassuming professor unlocked the genetic potential of the common fruit fly, transforming it into science's most famous laboratory animal.
Charles W. Woodworth's impact is woven into the very fabric of modern biology, though his name is often overshadowed by the giants who followed. A pragmatic entomologist at the University of California, Berkeley, he was the first to successfully breed Drosophila melanogaster in large numbers in a lab, seeking a convenient organism for his studies. Recognizing its potential—rapid reproduction, simple diet, clear mutations—he made a crucial suggestion to a visiting Harvard biologist, William E. Castle. This tip passed to Castle's student, Thomas Hunt Morgan, and the rest is genetic history. Beyond this foundational act, Woodworth was a formidable applied scientist. He helped draft California's pioneering pesticide law, battled mosquitos in China, and established Berkeley's entomology department. His career was a bridge between practical pest control and the dawn of pure genetic research, proving that a simple lab innovation can ripple out to redefine scientific inquiry.
1860–1882
Born during or after the Civil War, they built industrial America — the railroads, the steel mills, the first skyscrapers. An era of massive wealth, massive inequality, and the belief that the future belonged to whoever could build it fastest.
Charles was born in 1865, placing them squarely in The Gilded Age. The events that shaped this generation — world wars, depression, and rapid industrialization — shaped the world they entered and the choices available to them.

The standard laboratory food for fruit flies, a agar-based medium, is sometimes called 'Woodworth's medium'.
He was an early advocate for the use of biological controls in agriculture, not just chemicals.
The Pacific Branch of the Entomological Society of America awards a annual graduate student prize in his name.
