This grant provides continued support to the Leon Levy Center for Biography at CUNY (the Center) for the Sloan Fellowship for Science Biography. Dedicated to biographers focusing on the lives of scientists or technological innovators, the fellowship includes a $72,000 stipend for the selected biographer, funds for a research assistant, and a year-long residency at the Center that includes frequent meetings, lectures, and workshops with other biographers. Fellowships are awarded by an independent committee of scientists and scholars, who in the past has included Center’s Executive Director Kai Bird, winner of the Pulitzer Prize for his biography of Robert Oppenheimer, American Prometheus; Leslie Berlin, Project Historian for Stanford University’s Silicon Valley Archives; Harvard Professor and Charles Darwin biographer Janet Browne; physics historian Daniel Kevles; science biographer Nancy Greenspan; Princeton Professor and medical historian Keith Wailoo; and Pulitzer Prize-winning author Richard Rhodes.
