Biddy Mason won freedom from slavery, worked as a nurse/midwife and then became a successful entrepreneur and a generous contributor to social causes. She was born August 15, 1818 in Mississippi, U.S.A. as a slave on a plantation owned by Robert Marion Smith and Rebecca (Crosby) Smith. She had three daughters, Ellen, Ann and Harriet, whose father was reputedly Smith himself. In 1847, Smith became a Mormon convert and decided to move to the Utah Territory with his household and slaves. In this strenuous two-thousand-mile cross-country trek, Mason was responsible for herding the cattle. She also prepared meals, acted as a midwife and took care of her children.
In 1851, Smith moved his household again, this time to San Bernardino, California, where Brigham Young was starting a Mormon community. Smith probably did not know that California had been admitted to the Union in 1850 as a free state and that slavery was forbidden there. Mason petitioned the court and in 1856 won freedom for herself and for her daughters. She moved to Los Angeles and found employment as a nurse and midwife. Hard work and her nursing skills allowed her to become economically independent.
Mason was also very frugal and only ten years after gaining her freedom, she bought a site on Spring Street for $250. She instructed her children never to abandon this site. Mason was one of the first black women to own land in Los Angeles. This site is now in the center of the commercial district in the heart of Los Angeles. In 1884, she sold a parcel of the land for $1500 and built a commercial building with spaces for rental on the remaining land. She continued making wise decisions in her business and real estate transactions and her financial fortunes continued to increase until she accumulated a fortune of almost $300,000. Her grandson, Robert Curry Owens, a real estate developer and politician, was the richest African-American in Los Angeles at one time.
