Dorothy Mengering, David Letterman’s mom and one of his most popular “Late Night” and “Late Show” guests, died Tuesday.
She was 95.
Few details are known about Mengering’s death, but Letterman’s rep confirmed the news to the Daily News.
Mengering frequently appeared on her son’s late night shows via telephone as “Dave’s Mom” or “Dave’s Mom Dorothy,” before making her first on-screen appearance on “Parents’ Night” on “Late Night with Dave Letterman” in February 1986.
She would recur on his shows for several years, including as a commentator for the Winter Olympics in 1994, 1998 and 2002 where she interviewed, among others, then-First Lady Hillary Clinton andice skater Nancy Kerrigan.
“The positive response to my appearances on David’s show has nothing to do with my amateur abilities as a broadcaster. People enjoy seeing a mother and son together,” she wrote in her 1996 cookbook, “Home Cookin’ with Dave’s Mom.” “It’s that simple.”
Born in Indiana on July 18, 1921 as Dorothy Hofert, she married David’s father, Harry Letterman, in 1942.
In 1973, 10 years after her husband’s death, she married Hans Mengering, who died in March 2013.
The news comes just a day before Letterman’s 70th birthday.
“I’m so sorry to hear of Dorothy Mengering’s death, and so grateful that Dave shared her with us,” Stephen Colbert tweeted Tuesday night.
