Frank Bank, who starred on the 1957-1963 series Leave It to Beaver, died over the weekend, one day after turning 71. No cause of death was reported.
Beaver star Jerry Mathers, now 64, posted to his Facebook page:
"I was so sad to hear today of the passing of my dear friend and business associate Frank Bank. He was a character and always kept us laughing."
"My deepest condolences to Frank's family."
Bank first appeared on screen as the very young Will Rogers in the 1952 biopic The Will Rogers Story, before moving on to Leave It to Beaver.
Once the gentle sitcom about childhood was canceled, Bank continued to make sporadic TV appearances, though he moved on to become a stock broker.
Bank learned to handicap horses and read The Wall Street Journal during breaks on set, where he taught himself "everything there was to know about bonds."
Within three years of getting started, he said, he was earning $300,000 a year.
The late actor/broker is survived by his second wife, Rebecca Bank, and by two daughters from his first marriage to his high school sweetheart.
