Jean Tatlock pursued medicine while becoming active in Communist Party causes and opposing fascism. She was intellectually ambitious, psychologically perceptive, and deeply sensitive to injustice.

Suicide ruled
Tatlock was found drowned in her bathtub, with an unsigned note expressing despair. The coroner’s jury ruled suicide, with motive unknown.
