“Boy Meets World” alums William Daniels and Bonnie Bartlett Daniels celebrate 73 years of marriage

The "St. Elsewhere" stars wed in 1951 and share two children.

William Daniels and Bonnie Bartlett Daniels just celebrated a major relationship milestone.

The Boy Meets World alums have officially been married for 73 years. At 97 and 95 years old respectively, Daniels and Bartlett Daniels hold the record for Hollywood’s longest-lasting marriage.

"It seems like we're breaking records,” Bartlett Daniels told PEOPLE in a new interview. “I mean, we both broke a record when we got the Emmys on the same night for the same show. That was a record breaker, nobody had ever done that. Now, it seems like in Hollywood there are no marriages that are 73 years old, so we seem to break records."

The couple, who first met as students at Northwestern University, wed in Moline, Illinois on June 30, 1951. They share two children, sons Michael and Robert, after losing their firstborn William Jr. shortly after his birth.

Reflecting on seven decades of marriage, Bartlett Daniels said, "You never stop learning. You never stop being surprised. I never know. Every once in a while, he'll do something, and I think, 'Where did that come from? Where did that come from?' Or, he the same with me. We never stop being surprised by what somebody does."
