Katherine Davies Jones

Katherine Davies Jones (1860 – February 15, 1943) was an American botanist known for her developments in California horticulture.

Early life and education
Katherine Davies Jones was born in a log cabin in Berlin, Wisconsin, in 1860, the fourth of seven children. From age 16 (1876) to 1880, Katherine taught during the summers and went to school during the winters - attending Salem High School and eventually the University of Nebraska. Jones left the University of Nebraska due to illness in the family. In 1880, Jones along with her family moved from Nebraska to Vallejo, California, where she began teaching at private and public schools.

To continue her education, Katherine enrolled in UC Berkeley in 1893 to study botany and biology, and graduated in 1896 with a Ph.B.

Career
After Jones graduated from UC Berkeley in 1896 she went to work as a teaching aid for botany and zoology classes and kept records for the Botany Department at UC Berkeley. Jones also worked under Mr. A.V. Studbenrauch on Acacia for the Bureau of Plant Industry for the US Department of Agriculture. Acacia became Jones specialty, and in 1914 she wrote the entry on Bailey's Cyclopedia.

In 1913, Katherine was the first person hired by John W. Gregg at the University of California, Berkeley, who directed the Division of Landscape Gardening and Floriculture in the College of Agriculture to teach a course on plant materials as well as field work courses that involved students going outdoors to learn the name of trees and shrubs (Landscape at Berkeley, 4). Jones began the tradition of LA 49, a summer field trip course at UC Berkeley, which continued to be taught long after her retirement in 1930. She was listed in the faculty register as holding the position of Instructure in Landscape Gardening and Floriculture. Jones died on February 15, 1943, and willed her writings to the California Horticultural Society.
