This grant underwrites an annual fellowship at the Leon Levy Center for Biography (the Center) at the City University of New York (CUNY) to support an author writing a biography of a scientist, engineer, inventor, or mathematician. The Center is the only academic institution in the country devoted to promoting the practice of biography. Founded in 2007, its mission is to foster excellence in biographical writing and to encourage the academy to understand biography as a scholarly and rigorous discipline. Fellows receive a one-time award of $72,000, a graduate research assistant, dedicated office space, and access to both the Center’s fellow biographers and CUNY’s science faculty as advisors. Additional grant funds support outreach to publicize the fellowship with relevant audiences. The current fellows are: Dr. Laura J. Snyder, writing a biography of neurologist Oliver Sacks; Miriam Horn, writing a biography of biologist and conservationist George Schaller; and Patchen Barss, writing a biography of mathematician and cosmologist Roger Penrose.
