Biography/Administrative History
Edward Eric Walther was born in Dresden, Germany on August 14, 1892. At the age of 27 (1909) he emigrated to the United States.
After arriving in New York, he proceeded almost immediately to California where he took a job at the Mortimer Fleishhacker
estate in Woodside (1914-1916). Later work was with MacRorie-McLaren Company, a large San Francisco landscape and nursery
firm (1917). MacRorie-McLaren was contracted for the care of Golden Gate Park. Here, although he had no formal training in
horticulture or botany, Walther was employed until his retirement (1918-1957). In 1928 he took a six month leave to work
with the San Francisco County Agricultural Commissioner assisting with research work on aphids. He was also instrumental
in controlling pine bark beetle and citrophilous mealy bug. In 1933 Edward Eric Walther was named first Director of Strybing
Arboretum and Botanic Garden and he remained there until 1957.
Upon his retirement he was named Research Associate in the Department of Botany of the California Academy of Sciences (1958).
