Donaldina Cameron

Donaldina Cameron (1869–1968) was a pioneering social reformer and Presbyterian missionary whose work centered in San Francisco’s Chinatown from the late 19th to mid-20th century. Born in New Zealand to Scottish parents, Cameron immigrated to California as a child and eventually became superintendent of the Presbyterian Occidental Mission Home for Girls on Sacramento Street, a mission devoted to rescuing Chinese girls and women from sex slavery and indentured servitude and converting them to Christianity.
Sometimes called the "White Devil" or "Angry Angel of Chinatown," Cameron’s daring missions—often involving raids on brothels and safe houses—saved an estimated 2,000 to 3,000 Chinese immigrants including Tye Leung Schulze and Tien Fuh Wu. Her work combined rescue with education, conversion, and finding jobs or marriages to provide new opportunities for those she helped.
The organization she led through such challenges as the 1906 earthquake and the deadly Spanish Flu epidemic of 1918 is helping San Franciscans still, and is known as Cameron House: https://cameronhouse.org/.
