This week, the universe lost one of its most important figures in 20th-century musical theater, Stephen Sondheim. Karsh photographed Sondheim in 1986, between Sunday in the Park with George (1984), and Into the Woods (1987).
Sondheim’s accolades include eight Tony Awards, an Academy Award, eight Grammy Awards, a Pulitzer Prize, a Laurence Olivier Award, and a 2015 Presidential Medal of Freedom. He has a theater named for him both on Broadway and in the West End of London.
