Daniels began his career as a member of the singing Daniels family in Brooklyn. He made his television debut as part of a variety act (along with other members of his family) in 1943, on NBC, then a single station in New York.[7] He made his Broadway debut in 1943 inLife with Father,[8] and remained a busy Broadway actor for decades afterwards. His Broadway credits include roles in1776,A Thousand Clowns,On a Clear Day You Can See Forever, andA Little Night Music. He received anObie Award forThe Zoo Story (1960).
Daniels's motion picture debut was as a school principal in the 1963 anti-war drama filmLadybug Ladybug. In 1965, he reprised his Broadway role as a child welfare worker in the screen version ofA Thousand Clowns. In 1967 he appeared inThe Graduate as the father ofDustin Hoffman's character. In 1969, Daniels starred asJohn Adams in the Broadway musical1776; he also appeared in thefilm version in 1972. Two years later, he co-starred inRichard Donner's telefilmSarah T. - Portrait of a Teenage Alcoholic.[9] in 1978 and 1979 he again reprised his role as the outspoken John Adams in the filmsThe Bastard andThe Rebels, again about the American revolution, without seeming to ever break character. He is known as the quintessential John Adams.
Daniels's first network television appearance came in 1952 when he portrayed the youngJohn Quincy Adams, eldest son of John and Abigail Adams in theHallmark Hall of Fame dramaA Woman for the Ages. In 1976, he reprised the role as the middle-aged and elder John Quincy Adams in the acclaimedPBS miniseriesThe Adams Chronicles. He starred in the short-lived seriesCaptain Nice as police chemist Carter Nash. He appeared as acid-tongued Dr. Mark Craig inSt. Elsewhere from 1982 to 1988, for which he won two Emmy awards. Concurrently, he provided the voice ofKITT inKnight Rider from 1982 to 1986. Daniels said in 1982, "My duties onKnight Rider are very simple. I do it in about an hour and a half. I've never met the cast. I haven't even met the producer."[7]
Daniels reprised the voice-only role of KITT in 1991 for the television movieKnight Rider 2000, and again in the theatrical comedy movieThe Benchwarmers. He performed the role inAT&T andGE commercials about talking machines, and twice inThe Simpsons as well as at theComedy Central Roast of his co-star David Hasselhoff.[10] He reprised the role of KITT in the 2015 Lego-themed action-adventure video gameLego Dimensions.[citation needed]
Daniels portrayed strict but loving educatorGeorge Feeny at John Adams High School inBoy Meets World from 1993 to 2000. In addition to the previously mentioned 1967 superhero sitcomCaptain Nice, he was a regular on the 1970s TV seriesFreebie and the Bean andThe Nancy Walker Show.[citation needed]
A familiar character actor, he has appeared as a guest star on numerous TV comedies and dramas, includingSoap,The Rockford Files,Quincy, M.E.,Kolchak: The Night Stalker, and many others. In 2012, Daniels appeared in the ninth season ofGrey's Anatomy as Dr. Craig Thomas, an unlikely mentor to the character of Dr.Cristina Yang played by actressSandra Oh. His character, Dr. Thomas, died in the operating room while performing a procedure to repair a heart defect midway through the season, which forced Yang to move back to Seattle.[citation needed]
In 2014, Daniels reprised his role as Mr. Feeny in the pilot episode of theBoy Meets World spinoff,Girl Meets World. He cameoed in the final scene, praising the adult Cory Matthews for his parenting.[11] He made additional appearances in the second[12] and third seasons.[13]
In early 2023, he completed filming of the role of King Henry VI in the upcoming "Richard III".[14]
On October 14, 2025, at 98 years old, he appeared as a surprise guest onDancing with the Stars.[15]

Daniels has been married to actress and fellow Emmy Award winnerBonnie Bartlett since June 30, 1951; at 74 years, it is thelongest active Hollywood marriage as of January 2026. In 1961, Bartlett gave birth to a son,who died 24 hours later. They adopted two sons. They also have four grandchildren, two through their son Michael, and another two through their other son Robert.[16][17]
Bartlett and Daniels both served on theScreen Actors Guild's board of directors.[18]
Daniels refused the 1969 Tony Award nomination for Featured Actor in a Musical in1776 due to his insistence that the part of John Adams was a leading role rather than supporting.[19] He was ruled to be ineligible for the Best Actor nomination because of the technicality that his name was not billed above the title of the show.[20]
From1983 to 1987, Daniels' work onSt. Elsewhere earned him five consecutive nominations for thePrimetime Emmy Award for Outstanding Lead Actor in a Drama Series, winning in 1985 and 1986. In 1986, Daniels and Bartlett, who played his fictional wife onSt. Elsewhere, won Emmy Awards on the same night (Bartlett forSupporting Actress in a Drama Series), becoming the first married couple to accomplish the feat sinceAlfred Lunt andLynn Fontanne in 1965 for a production ofThe Magnificent Yankee for theHallmark Hall of Fame.[21]
