Gene Wilder, the frizzy-haired actor who brought his deft comedic touch to such unforgettable roles as the neurotic accountant in "The Producers" and the mad scientist of "Young Frankenstein", has died. He was 83.

Wilder's nephew said Monday that the actor and writer died late Sunday at his home in Stamford, Connecticut, of complications from Alzheimer's disease. No funeral arrangements have been announced.

Jordan Walker-Pearlman said in a statement that Wilder was diagnosed with the disease three years ago, but kept the condition private so as not to disappoint fans.

Wilder started his acting career on the stage, but millions knew him from his work in the movies, especially his collaborations with Mel Brooks on "The Producers," ''Blazing Saddles" and "Young Frankenstein".

Wilder was close friends with Richard Pryor and their contrasting personas were ideal for comedy. They co-starred in four films: "Silver Streak," ''Stir Crazy", ''See No Evil, Hear No Evil" and "Another You".
