After more than half a century, Jerry Lewis has ended his run as national chairman of the Muscular Dystrophy Association.
The actor-comedian-filmmaker, 85, had served in the role since the early 1950s.
“Jerry Lewis is a world-class humanitarian, and we’re forever grateful to him for his more than half century of generous service to MDA,” said R. Rodney Howell, M.D., chairman of the board for the MDA.
Lewis announced in May that he was retiring as host of the MDA’s annual Labor Day telethon. He had planed to make his final appearance on this year’s Sept. 4 telethon, but Howell says that won’t happen.
“We will not be replacing him as MDA national chairman, and he will not be appearing on the [Labor Day] telethon,” Howell says.
