He was 78.
“Alan died peacefully on Monday, surrounded by family,” Hammerman told CNN.
Kalter died at Stamford Hospital, with his wife Peggy and daughters Lauren Hass and Diana Binger by his side.
Kalter became the announcer on “Late Show” in 1995 and worked until the show ended in 2015. He had replaced announcer Bill Wendell.
Former “Late Show” writer Carter Bays wrote on Twitter, “Alan Kalter RIP. Between him and Tony Mendez it’s a heartbreaking time. To us Late Show writers Alan was so much more than just the ‘From New York…’ guy. He was our muse. We loved writing for him. Such a cheerful presence on the show. And around the office. Rest easy Big Red.”
In addition to his voice work on the show, Kalter often appeared in segments in which he would pretend to get angry and storm off stage or sometimes rip his shirt off.
Kalter had done many voiceovers for national radio and television commercials and also was the announcer for “To Tell the Truth,” “The $25,000 Pyramid,” “The Money Maze” and “The $100,000 Question.”
