Meara was born in Brooklyn on September 20, 1929. She met Stiller in 1953 -- when she was 23, he was 25 and both were out-of-work actors -- and the two wed a few months later. Their daughter Amy Stiller was born in 1961, and Ben was born in 1965.
The native New Yorker was best known for being in the comedy duo Stiller and Meara with her husband, as well as for her work on All My Children, Archie Bunker's Place and Awakenings.
Three days after she passed, Ben shared a photo of his mom on Instagram. "She was an extraordinary person," he wrote. "Miss her."
