On Dec. 21, 1970, the Church of One Tree was dedicated as the site of the Robert L. Ripley memorial museum. Ripley, born in 1893 in Santa Rosa, started his career as a cartoonist at Santa Rosa High School and became a newspaper cartoonist in San Francisco and New York. His internationally popular “Believe It or Not” cartoon feature ran from 1918 until his death in 1948. In December 1947, Ripley purchased the Church of One Tree from the First Baptist Church of Santa for the purpose of creating a museum. The one-of-a-kind structure was built from the lumber of one redwood tree felled near Guerneville in the 1870s.
