Max Eisen, a Broadway press agent from the days when feeding tidbits of gossip to columnists like Walter Winchell and staging stunts were standard practice for stirring up a bit more box-office appeal, died on Nov. 23 at his home in Manhattan. He was 91. His son, Glenn, said he died of natural causes. From his office above Sardi's on West 44th Street -- its walls lined with framed posters from the shows he promoted -- Eisen worked the phone and clacked out press releases on his battleship-gray electric typewriter for more than four decades. From 1954 to 1997 he was the press agent for more than 60 Broadway shows and dozens of off-Broadway productions. In 1964, when he was representing five Broadway shows at once, Eisen staged a mini-Olympics in Shubert Alley -- a block-wide stretch between 44th and 45th Streets -- in which 30 performers from seven shows raced before eight photographers, an ABC television crew and a crowd of 600. A dancer in the 'Folies Bergere' won three of the eight events: the 50-yard dash, the 100-yard dash and the half-mile (back and forth) walk. 'This is the crowning achievement in lunacy,' a member of Eisen's staff said at the time. Among the productions Eisen promoted were 'The Matchmaker' (1955-57), 'The World of Charles Aznavour' (1965), 'You're a Good Man, Charlie Brown' (1971), 'Raisin' (1973-75), a revival of 'Guys and Dolls' (1976-77), 'The Effect of Gamma Rays on Man-in-the-Moon Marigolds' (1978) and a revival of 'The Wiz' (1984). Born in the Bronx on Oct. 19, 1918, Eisen was the only child of Samuel and Molly Eisen, who owned a candy store. Besides his son, Glenn, he is survived by his wife of 44 years, the former Barbara Glenn; his daughter, Lee Kittay ; and five grandchildren. Eisen served in the Army in Europe during World War II. For several years after the war, he worked in the circulation department of what was then The Paris Herald Tribune. In the early 1950s he returned to New York and started his company. In an interview with The New York Times in 1997, Eisen spoke about the excitement of waiting on opening nights for those late-night newspaper reviews. There were flops, like 'Some of My Best Friends,' starring Ted Knight, in 1977. 'Everybody congratulated him, everybody shook his hand,' Eisen said. 'But nobody bought a ticket.' He reminisced about memorable shows, like the 1971 revival of 'Long Day's Journey Into Night,' starring Robert Ryan, Stacy Keach and Geraldine Fitzgerald. 'Just look at those names,' he said.
