We all had that one teacher who impacted our lives more than any other. And if you didn’t have that person in the classroom, you might have known him through your television set. For seven seasons from 1993 to 2000, William Daniels portrayed Mr. George Feeny on Boy Meets World. His character was there to mold the minds of Corey Matthews, Shawn Hunter, Topanga Lawrence, and their classmates. But his wisdom went far beyond the set. Mr. Feeny touched so many lives, and William Daniels brought that iconic character to life. On March 31, 2026, William and we suppose Mr. Feeny turned 99 years old.
