Wertimer's manager Brad Lemack said Tuesday that the 89-year-old actor died at a Los Angeles-area nursing home on Jan. 2, following a November fall at his home in Burbank.
A native of Buffalo, N.Y., and a Navy pilot during World War II, Wertimer had one-off roles on dozens of TV shows from the early 1960s through the late 1980s, including "Car 54 Where Are You?" and "Mary Tyler Moore."
But he was best known by far as Ralph Hart, the uniformed, mustachioed doorman at the luxury apartment building on "The Jeffersons," the "All In the Family" spinoff that ran from 1975 to 1985.
The show's star, Sherman Hemsley, died July 24.
