About the author
Born in Iowa in 1841, Warren Olney Sr. served in the Union Army during the Civil War before studying law and building his career in California. He became a prominent attorney and public figure, with a life that stretched across law, politics, and public service.
Olney is especially remembered as one of the founding members of the Sierra Club, working alongside John Muir and others at a time when ideas about conservation were taking shape in the American West. His career also included elected office: he served as mayor of Oakland from 1903 to 1905.
He died in 1921, but his name remained well known in California civic life through both his own work and his family’s public legacy. For readers interested in the intersection of law, politics, and early conservation, his story offers a vivid glimpse of the era.
