ET Canada has reached out to Einstein’s rep for comment.

Friend and “Curb” co-star Richard Lewis also mourned Einstein on Twitter.

I’m in shock.
I knew him forever. ♥️to his loved ones. His long career is hard to match. His role on #curbyourenthusiasm was excruciatingly brilliant! Our cast and crew will be devastated.
He was so loved. He told me how much he loved LD and Curb. RIP buddy. ⁦@HBO⁩ pic.twitter.com/G8f5PoffuF

Born in 1942, Einstein started off his career as an Emmy-winning comedy writer for “The Smothers Brothers Comedy Hour”.

He later went on to create and star as the beloved satirical stuntman character Super Dave Osborne, hosting the variety “Super Dave” on Global from 1987 to 1991.

In one famous bit, Super Dave attempted a jump from Toronto’s CN Tower.

Remembrances poured on social media for Einstein.

#BobEinstein. What a mind! What a great friend. Brilliantly funny always. We started together on the Smothers Brothers
Loved every moment working with him on Curb. He was one of a kind.
Great loss to the comedy world. We will all miss him so. #RIP

Oh no, Super! Bob Einstein’s character, Super Dave Osbourne, was so embedded that we all called him Super. Except for his grandkids, who called him Grandpa Super. I will miss his brilliant comedy and vice-like hugs.

So sad to get the news about Bob Einstein. Any day this guy was on the Curb set was a good day. Then my phone would always ring that night and that screechy voice would ask, "How f'in funny was that scene today?" And it was always VERY f'in funny. RIP Bobby.

His name was Bob Einstein, but we all called him Supe. Super Dave was a great friend and the master of a joke you could see coming for miles that still killed when it arrived. I will miss him https://t.co/JRkMp8XkCJ

Rest in Peace, Bob Einstein = Super Dave Osborne = Marty Funkhouser
Funny, smart, didn't suffer fools gladly
Can think of several 70-something guys whom I'd prefer to be dead instead of him. pic.twitter.com/2N0ZItf9Ve

If you haven’t seen Bob’s episodes of comedians in cars getting coffee, check them out. Sad to hear about this. I really enjoyed watching his work. https://t.co/8CBqZ8eQGq

RIP Bob “Super Dave Osborne” Einstein, from Bizarre to Super Dave to Curb Your Enthusiasm and Arrested Development you provided hours of joy that will be missed.

RIP, Bob Einstein, aka Super Dave Osborne, aka Marty Funkhouser. Marty didn't appear on Curb until s4, yet Einstein and Larry David had a rapport that made it seem like he'd been there forever. https://t.co/KKF6UE8xPz

R.I.P. Bob Einstein. It's very frustrating that his brilliant one-scene performance as the sporting goods salesman from MODERN ROMANCE isn't on YouTube because it should be there for posterity's sake.

Rest in peace to "Super Dave" Bob Einstein, who had some of the best scenes with Larry David as Marty Funkhouser in Curb Your Enthusiasm. Gonna have to re-watch some of them tonight. pic.twitter.com/P48DHJrbmS

Two weeks ago, @DavidLevien and I standing around on set with @kevinpollak telling Bob Einstein jokes. We said that night, and have said many times, that nobody made us laugh harder than Bob Einstein. He was the best joke teller of all time. Working with him on o13 was an honor.
