Few recognize his name, yet Yousuf Karsh is acknowledged as one of the 20th century’s leading portrait photographers; his iconic images of Humphrey Bogart, Ernest Hemingway, Winston Churchill, Albert Einstein, and Elizabeth II are instantly recognizable. A young refugee from the ethnic cleansing of Turkish Armenians in 1916, Karsh became a world traveler over his 60-year career; when he died in 2002 at the age of 94, he left a legacy of 50,000 portraits. His remarkable life is told here by cultural historian Maria Tippett, winner of the Governor General’s Literary Award and the Macdonald Prize for Canadian History, in a biography that includes 60 of Karsh’s most celebrated portraits and reveals his techniques behind the camera.
