When Caroline Hirsch, owner of New York City's renowned stand-up club Carolines on Broadway, came to know Robin Williams, he was just building his name on TV with Mork & Mindy.
But soon enough, in the mid-1980s, Williams became one of the big stars to appear on the stage of the famous Times Square comedy club. In the decades since then, Hirsch said, he would return to support other performers.
"Who's going to fill that, that of the comedy world?" she told TIME. "Because we really don't have that kind of unique person. I haven't seen it. And I don't know who will come up the ranks to be that guy, who is always there for everybody."
