Kevin Dobson labored as a trainman, brakeman and conductor for the Long Island Railroad in his pre-acting days. While he has done plenty of stage work, Dobson is best known for his TV accomplishments. He was signed in 1973 for what turned out to be a five-year run on Kojak, playing Telly Savalas' trusted assistant (and occasional punching bag) Detective Bobby Crocker; when Kojak was revived as an occasional series in 1989, Dobson guest-starred as Crocker (now a state prosecutor) in one episode. In 1981, Dobson starred in the San Francisco-filmed cop series Shannon, which lasted but a single season. The very next year, Kevin Dobson launched his longest series-TV stint in the role of attorney M. Patrick McKenzie, second husband of Karen Fairgate (Michelle Lee),on the prime-time serial Knots Landing.
