Earl L. Calvert

California collector Earl Lloyd Calvert was born in Kirksville, Missouri on January 24, 1904, the son of a professor and grammar school teacher. The family moved to Washington state between 1910 and 1920, and then on to California in the 1920's, where Earl earned a degree in Chemistry and took a job as a chemist for a paint company ca. 1930. He became interested in minerals when his sister was attending Pasadena City College and needed his help in assembling a small collection as a mineralogy course assignment. He began building his own collection, and became known as one of the most enthusiastic collectors in California. He was living in San Gabriel, California in 1932 when he was elected treasurer of the recently formed Mineralogical Society of Southern California. He married Esther Evarts (1910-2001) in Long Beach, California in 1940, and together they had three sons: Edward, Carl and John.

Calvert visited many famous mining areas to collect minerals, including the Tri-State area, Minnesota, the Western States and northern Mexico, with his collecting partners Louis Vance (1901-1964) and Wendell O. Stuart (1903-1994). He wrote an article for Rocks & Minerals magazine in 1939 describing their trip to Guanajuato.

Earl Calvert died in Monrovia, California on November 20, 1964. His mineral collection, heavy in Los Lamentos and other Mexican specimens, was acquired after his death by mineral dealer Rock H. Currier (q.v.) of Jewel Tunnel Imports.
