William Daniels is a name that resonates with generations of television and theater audiences. With a career spanning over 80 years, he has played some of the most iconic roles in American entertainment history. From the commanding presence of Dr. Mark Craig in St. Elsewhere to the wise and endearing George Feeny in Boy Meets World, and even the unforgettable voice of KITT in Knight Rider, Daniels’ versatility and depth as an actor have made him a household name.
Early Life and Background
Born on March 31, 1927, in Brooklyn, New York, William David Daniels was raised in a working-class family. His father, David Daniels, was a bricklayer, and his mother, Irene, was a homemaker who supported her children’s creative ambitions.
Daniels was introduced to show business at a very young age. Along with his siblings, he performed in the “Daniels Family” song-and-dance troupe. This early exposure led him to television at just 14 years old when he appeared in one of the first experimental broadcasts in 1941. By 16, he made his Broadway debut in Life With Father, setting the stage for a lifelong acting journey.
Stage Career
Though most people know him from TV and film, William Daniels first found his footing on the stage. He spent his early career immersed in theater, honing his skills in both comedic and dramatic roles. His standout performance in Edward Albee’s The Zoo Story in 1958 earned him an Obie Award, recognizing his exceptional work in Off-Broadway productions.
Perhaps one of Daniels’ most defining stage roles came in the form of John Adams in the original Broadway musical 1776. His portrayal of the passionate founding father won critical acclaim. When the play was adapted into a film in 1972, Daniels reprised his role, delivering a powerful performance that captured both the character’s grit and conviction.
Film Career
Daniels made his film debut relatively late, in 1963, with the Cold War drama Ladybug Ladybug, portraying a school principal. In 1965, he appeared in A Thousand Clowns, where he played a child welfare worker, showcasing his ability to handle emotionally complex roles.
However, his most memorable film role came in The Graduate (1967), in which he played the father of Dustin Hoffman’s character, Benjamin Braddock. The film became a cultural milestone, and Daniels’ performance—though understated—added to its emotional resonance.
Television Career
Television proved to be the platform where William Daniels truly became a beloved figure.
Captain Nice (1967)
Daniels’ first major television role came in the quirky superhero comedy Captain Nice. Playing Carter Nash, a mild-mannered chemist who transforms into a reluctant hero, Daniels brought charm and humor to a short-lived but memorable series.
St. Elsewhere (1982–1988)
One of his most critically acclaimed roles was that of Dr. Mark Craig in the medical drama St. Elsewhere. His portrayal of the brilliant but arrogant surgeon earned him two Primetime Emmy Awards. The show itself was a landmark series, known for its gritty realism and ensemble cast.
Knight Rider (1982–1986)
At the same time he was filming St. Elsewhere, Daniels lent his distinctive voice to the AI character KITT in Knight Rider. Though he never appeared on-screen, his work as the talking car became iconic, with KITT becoming a fan-favorite element of the show. Daniels recorded his lines separately, often on his days off, showcasing his dedication and versatility.
Boy Meets World (1993–2000)
Arguably his most enduring role came in the form of George Feeny, the strict but loving teacher and mentor in Boy Meets World. Over the course of seven seasons, Mr. Feeny guided young Cory Matthews and his friends through the challenges of adolescence and young adulthood. Daniels brought wisdom, warmth, and humor to the role, creating a character who remains beloved by audiences to this day.
Later TV Appearances
Daniels reprised his role as Feeny in Girl Meets World (2014–2017), appearing in a handful of episodes that paid tribute to the legacy of the original series.
