Reclusive and virtually deaf, south-sider Herman Menzel spent most of his adult life painting subjects close to home: the lakeshore, jazz clubs, fish at the Shedd Aquarium. Supported by his wife, Willa Hamm, a successful commercial artist, Menzel rarely exhibited and he refused to sell any of his work. The Chicago Historical Society exhibit, A Rediscovered Regionalist: Herman Menzel, is an updated version of the retrospective organized by his widow after he died in 1988; it runs through April 17 at the society, Clark at North Avenue. Hours are 9:30 to 4:30 Monday through Saturday, noon to 5 Sunday. Admission is $3, $2 for seniors and students, and $1 for children. Call 642-4600 for more.
