An expended version of this short biography may be found here.

A writer, biologist, and sexuality educator, she was born July, 5, 1873, in California. There she knew John Muir, and went hiking with him in the Sierra Nevada mountains. She received her A.B. in English from Stanford University in 1895, and her A.M. in entomology in 1902. After graduating from Stanford, she taught high school from 1900-1907; was assistant in nature study at the Univ. of Chicago, 1907-1909; taught biology at Calif. State Teachers College in Chico in 1918; was a lecturer at Stanford 1921-1923.

She married Vernon Mosher Cady on Dec. 15, 1908, at the Abraham Lincoln Center in Chicago. The Abraham Lincoln Center was a Unitarian church and community center with permanent and transient residents; Bertha and Vernon had both lived in the Center in the summer of 1908. They were probably wed by Rev. Jenkin Lloyd Jones. They had two children: Carol (b. c. 1910) and Jean (b. c. 1913).

She was a graduate student at Stanford 1920-1922, and received her Ph.D. in entomology (at age 50) in 1923. Subsequently, she worked for the Girl Scouts as a naturalist from 1924-1936.

Bertha’s career encompassed biology and education. She and her husband co-wrote The Way Life Begins: An Introduction to Sex Education (New York: American Social Hygiene Assoc., 1917). As the Girl Scout National Naturalist, she wrote for, or wrote in their entirety, many Girl Scout publications.

While she was at Stanford earning her Ph.D., she was active with the Unitarian Church of Palo Alto. She taught the 4th and 5th grade Sunday school class at the Unitarian Church of Palo Alto in 1921-22.

She died Jan. 26, 1956.
