He serves as chairman of the New Dramatists, a group that nurtures young playwrights; he is a board member of Fountain House, a halfway house for ex-mental patients; and he is chairman of the Theatre and Music Collection of the Museum of the City of New York.

On Monday through Thursday, Weissberger lives in a luxurious Eastside apartment that he shares with his longtime friend, theatrical agent Milton Goldman. Each Friday after work, Weissberger departs for Seacliff, Long Island, where he owns a house overlooking the ocean. Goldman and Weissberger, whose careers have run a parallel course during the 35 years of their acquaintance, travel widely each summer, generally spending a month in London, where both have many clients.

"Our interests are very similar, except that I am an opera buff, and Milton is not. He's a realist. I started going to opera when I was 10 years old, so I don't mind if a 300-pound soprano dies of consumption in _Traviata_, as long as she sings beautifully."

An avid art collector, Weissberger buys only what he has room to display on the walls of his home and office. For the past 30 years his chief hobby has been photography. He has published two volumes of his work -- _Close Up_ (1967) and _Famous Faces_ (1971). Although he has never taken a photography course, and never uses flash, he captures the essence of his subjects through his rapport with them. "I have discussed the possibility of doing a photo book of children I've taken around the world," he notes. "And now, of course, I have enough photos for a second volume of famous faces."

His vigorous appearance to the contrary, Weissberger claims to get little exercise. "I have one of those stationary bicycles at home, but I've never gotten round to using it. And I've got to do so before I next see my doctor, or I won't be able to face him. ... It's interesting how doctorial advice changes. I remember several years ago, it was not considered a good idea for people who were no longer young to climb stairs, and now my doctor says that climbing stairs is the best thing I can do for my constitution."

So closely connected are the various aspects of his life that Weissberger is able to say: "There's no demarcation between my workday and my play day. People ask me when I'm going to retire, and I say there's no need for me to retire, because I enjoy my work so much. I become part of people's lives. I become privy to their problems. It is, in many ways, an extension, an enhancement of my own life to be able to participate in the lives of my clients. I remember a few months ago, when Lilli Palmer was sitting right there, and I said, 'Lilli, what a lucky person I am. I'm having to do a tax return and I'm doing it for Lilli Palmer.' Because there sat this beautiful, charming, intelligent, lovely lady, and I was representing her professionally. For me, I can't think of any profession that could possibly be more rewarding."
