Liz Sheridan, known for playing Jerry Seinfeld’s mom on the widely popular NBC show "Seinfeld," has died, according to multiple reports. She was 93.
Sheridan died peacefully in her sleep of natural causes, TMZ reported on Friday.
"Liz was always the sweetest, nicest TV mom a son could wish for. Every time she came on our show it was the coziest feeling for me. So lucky to have known her," Seinfeld posted on Twitter Friday.
Born April 10, 1929, in Rye, New York, Sheridan began her screen career in titles such as "The White Shadow," "Kojak" and "Gimme a Break!"
She also appeared in dozens of episodes of "ALF" from 1986 to 1990. From the moment Sheridan was cast as Helen Seinfeld, fans of the series raved of her motherly charm and being hilariously overprotective of her son.

Sheridan was also a prominent Broadway star, starring opposite Christopher Lloyd and a young Meryl Streep in the 1977 musical "Happy End."
She famously dated late actor James Dean and penned a book about their romance, "Dizzy and Jimmy."
Sheridan is survived by her daughter and son-in-law.
News of Sheridan’s death comes less than two weeks after the death of her fellow "Seinfeld" co-star, Estelle Harris, who played George Costanza’s mom.
