From Wikipedia:
Bridget ("Biddy") Mason (born August 15, 1818 in Hancock County, Georgia - died January 15, 1891 in Los Angeles, California) was an African American nurse, and a California real estate entrepreneur and philanthropist.
Mason worked in Los Angeles as a nurse and midwife. Saving carefully, she was one of the first African Americans to purchase land in the city. As a businesswoman she amassed a small fortune of nearly $300,000, which she shared generously with charities. She was instrumental in founding a traveler's aid center, an elementary school for black children, and was a founding member of First African Methodist Episcopal Church, the city's first and oldest black church.
