"In his many stage performances, as well as on film and TV, we all felt like we knew him personally; he had that kind of approachability," Charlotte St. Martin, executive director of The Broadway League said about Klugman in a statement posted on the group's website. "As with all fine actors, he made the work look effortless. Our thoughts are with his fans, friends, and family."
