Josephine Baker was an American born jazz and blues performer who moved to France in the 1930s, partially to escape American racism. She became wildly popular in Paris and returned to the US in the 1950s and 60s and participated in the Civil Rights Movement. Josephine Baker had several husbands and many lovers, some of them female. Although she lived in a homophobic time, by today's standards, she would likely be considered to be bisexual. Here's a bit more about the life of Josephine Baker.
