Esther Rosencrantz was born in San Francisco, November 18, 1876. She received her undergraduate education at Leland Stanford
Junior University, graduating A.B. in 1899. She attended medical school at Johns Hopkins University, from which she received
her MD in 1904, being the first woman from California to receive a medical degree from Hopkins. While at Hopkins, Dr. Rosencrantz
studied under the great four: Welch, Kelly, Halsted and Osler. The last, Dr. William Osler created such an impression on Dr.
Rosencrantz that throughout her life she collected any materials by or about Dr. Osler that she could buy, exchange or coax
from other collectors. Her collection, now part of the Special Collections Division at UCSF, is perhaps the most comprehensive
(up to the time of her death in 1950), outside of that at the Osler Library at McGill University in Montreal, Quebec.
