Bertha Wilhemina Candrian (October 2, 1862 - March 14, 1944) was a San Francisco housewife and map draftswoman. Bertha, née Harry, was born in Illinois. Little is known of her early life or education, but she married Hermon Anton Candrian (1852 - 1928) was living with her husband in San Francisco as early as 1906. Hermon Candrain became a prominent map publisher and as early as 1906 began leaning on Bertha to draft his maps. Few maps actually feature her imprint, B. W. Candrian, but it can be assumed she was an active part of the firm until her husband's death in 1928.
