Thayer Grimes worked for the Public Works of Art Project and then completed one known easel work for the WPA Federal Arts Project entitledMoses and the Ten Commandments. It was allocated to the Westport School System. Born in Nebraska on September 27, 1886, both Thayer and his wife Jessie H. are listed in 1939 as members of the Silvermine Guild of Artists, and both are listed in the Weston directory for that year as artists living on Lyons Plains Rd. They later moved to Los Angeles where Grimes died on February 4, 1949.
