Actor Frank Bank, best known as the bully Clarence "Lumpy" Rutherford on the classic sitcom “Leave it to Beaver” had died, according to multiple reports. He was 71.

No cause of death or photos of Bank were immediately available.

His co-star on “Beaver” Jerry Mathers, announced the news of his passing on Facebook: "I was so sad to hear today of the passing of my dear friend and business associate Frank Bank, who played Lumpy on Leave it to Beaver. He was a character and always kept us laughing. My deepest condolences to Frank's family."

Mathers played Theodore “Beaver” Cleaver. The show ran from 1957 to 1963.

For several years after “Leave it to Beaver” ended, Bank continued to be on TV. He made scattered appearances on “Hollywood Squares” and “Family Feud.”

Later, he left the spotlight to become a bond broker.

But even with his new job he still kept his ties to the “Beaver” clan. Mathers and Barbara Billingsley were some of his clients.

Billingsley, who played June Cleaver, once told People magazine: "Frank is certainly brighter than Lumpy Rutherford, and a very good stockbroker."
