Stan Galli, American (1912 - 2009)
According to Walt Reed's "Illustrator in America" Stan Galli was born in San Francisco and had a variety of jobs as a young man trying to survive through The Depression. He eventually saved enough to get an education at the California School of Fine Art. His art career afterwards was interrupted by service in WWII, and though he returned to a partnership in a San Francisco art service after the war, he found the business aspects didn't suit him. TI list member Bruce Hettema mentions Galli as having worked for his company, P&H Creative, so I wonder if this might be the art service mentioned, but in an earlier incarnation? He chose instead to become a freelance illustrator, a decision that proved to be very rewarding.
Galli had a long and successful career illustrating for many major American publications, but perhaps most notable is his key role in a long campaign for Weyerhauser Timber. Galli did over fifty paintings for the company on the theme of conservation and brought in other artists like Fred Ludekens and Bruce Bomberger to produce ads as well.
Galli is in the Society of Illustrators Hall of Fame and his work is in the U.S. Air Force Art Collection.
