Bonnie Bartlett turns 96 on June 20, 2025, and just ten days later, she and William Daniels will celebrate an incredible 74 years of marriage — which is the longest marriage between two currently living celebrities. Daniels, now 98, is best known to many as Mr. Feeny from Boy Meets World; a decade earlier, the couple appeared on St. Elsewhere together. But their love story began decades earlier, when both were college students. And despite early struggles, personal loss and the unpredictable nature of show business, they stayed the course together.
