Speaking in 2012, he said: “Around 3:30, 4 oโclock, I would become โฆ depressed. To break up the monotony of accounting, which I wasnโt very good at to begin with, I would call Ed and โฆ we would improvise over the phone.
“I called him one time and I said, โMr. Smithers? Yeah, this is Bob at the yeast factory, and we have a fire here, sir. The fire company, theyโre pouring water on itโฆ Mr. Smithers, Iโm gonna have to run up to the second floor’.โ
Newhart married Virginia ‘Ginny’ Quinn in 1963, and the pair were married until her death in 2023 at the age of 82.
He is survived by his children, Robert Jr., Timothy, Courtney and Jennifer, and 10 grandchildren.
