Gertrude Stein (1874-1946) was born in Pittsburgh to a prosperous German-Jewish family. She was educated in France and the United States, worked under the pioneering psychologist William James, and later studied medicine. With her brother Leo she was an important patron of the arts, acquiring works by many contemporary artists, most famously Picasso, while her home became a popular meeting place for writers and painters from Matisse to Hemingway. Her books include Three Lives, Tender Buttons, and The Autobiography of Alice B. Toklas.

Steven Meyer is the author of Irresistible Dictation: Gertrude Stein and the Correlations of Writing and Science (2001, Stanford UP) as well as half a dozen essays on Stein's narrative practices.

Material from Robust Empiricisms has appeared in numerous edited collections.
