Edmund Beecher Wilson maintained a private journal than traverses much his tenure at Columbia University (12/5/1903-5/24/1928). Wilson includes frank assessments of undergraduate and graduate students, many of whom would become leaders in the fields of biology, genetics, and zoology. For example, he writes of Rebecca Lancefield—who would become a leading microbiologist—"good on the whole, faulty in spots" (5/26/1917). Other prominent graduate students include A. Franklin Shull, Jack Schultz, Hermann Muller, Calvin Bridges, Alfred Sturtevant, and Curt Stern (for whom APS possesses two diaries). Researchers interested in the history of science, education, and the research university will find this volume particularly useful.
