Liz Sheridan, Jerry Seinfeld's TV mother, is remembered: 'So happy to have known her.' ...

Saxon went on social media to pay homage to his TV mom, who at the age of 93.

"Liz was always the sweetest, nicest TV mom a kid could wish for," the comic and actor wrote on Twitter. "Every time she came on our show it was the coziest feeling for me. I'm so glad to have known her."

When Jerry was cast as her sister on Seinfeld, Sheridan had already recurred in three dozen episodes of ALF from 1986 to 1990, then appeared in more than 20 episodes of the "show about nothing," which spanned from Episode 2 to the 1998 finale.

Seinfeld was first announced on NBC as a summer replacement for The Seinfeld Chronicles in July 1989. From there, the series also featured Jason Alexander, Julia Louis-Dreyfus, and Michael Richards, but the plum after the Thursday slot became the postseason top 25 in the Nielsen rankings in 1992-93.

Seinfeld took over the Cheers' 9 p.m. slot for the 1993-1994 season and ended it ranked No. 3 among all primetime shows. It would finish No. 1 or No. 2 overall for the remainder of its nine-season run, finishing in 1998.

Sheridan was the last surviving "parent" from Seinfeld. Estelle Harris, who played George Costanza's mother Estelle, and Jerry Stiller, who played Frank Costanza, were both a part of Barney Martin's role. Morty Seinfeld died in 2005.

Liz was always the sweetest, most welcoming TV mother a son could wish for. Every time she came on our show it was the coziest feeling for me. So glad to have had her perform.
