1887–1977
An influential American ecologist and geneticist, this University of Michigan scholar spent decades studying mammals, heredity, and the patterns that shape life in different habitats. He is especially remembered for work that helped give rise to the Dice coefficient, still widely used to compare similarity.

by Lee R. (Lee Raymond) Dice
Born in Savannah, Georgia, on July 15, 1887, he became a major figure in American ecology, genetics, and mammalogy. He earned his B.A. from Stanford University in 1911, then completed both his M.S. and Ph.D. at the University of California in 1914 and 1915.
He spent almost his entire professional career at the University of Michigan, where he taught for roughly four decades and built an international reputation as a researcher. His work ranged across ecology and animal distribution to heredity studies, and he is widely associated with the independently developed Sørensen–Dice coefficient, a method for measuring similarity between sets.
He died on January 31, 1977. Available sources also describe his long connection with the University of Michigan’s Museum of Zoology and related research programs, reflecting a career devoted to careful fieldwork as well as broad scientific ideas.
