Comedy mother Mitzi Shore died Wednesday (April 11) at her home in West Hollywood, reports the Los Angeles Times.

Shore, who is the mother of comedian Pauly Shore and owner of Los Angeles’s famed Comedy Store, had been battling Parkinson’s disease for quite some time. However, the cause of her death is currently unknown.

“It is with great sadness and very heavy hearts that we report the passing of Mitzi Shore. Mitzi was an extraordinary woman and leader who identified, cultivated and celebrated comedy’s best performers,” The Comedy Store said in a statement shared on Twitter. “She helped change the face of comedy and leaves behind an indelible mark and legacy in the entertainment industry and stand-up community. We will all miss her dearly.”

Shore is credited for the creation of comedy’s most celebrated comedians. Jim Carrey, Jay Leno, and Robin Williams are amongst the long list of heavy-hitters groomed and nurtured by Shore’s Hollywood “boxer’s gym” (The Comedy Store), as Shore once told the LA Times in 1994. David Letterman even babysat her children.

The Comedy Store opened in 1972 on Hollywood’s famed Sunset Strip.

Comedians all over the country mourned her death.
