MacLaughlin's family contained "a long line of ministers", and he planned to study for the ministry when he entered college.[3]
Television
MacLaughlin originated the role of lawyer Chris Hughes on As the World Turns in 1956, and played the role until his death in 1986. Contract negotiations kept him (and his on-screen wife Helen Wagner) off the soap for most of the early 1980s, but the show finally welcomed the two back in a big storyline with heavy uses of past clips from the show. In the story, Chris and his wife Nancy were celebrating their fiftieth wedding anniversary. In real life, As the World Turns was celebrating its thirtieth anniversary on the air. [citation needed]
Prior to TV, MacLaughlin was active on radio, beginning in 1933.[5] He starred as the title character on radio's David Harding, Counterspy in the 1940s and 1950s. In 1945, he joined the cast of The Romance of Helen Trent, in the role of Dwight Swanson, "a rancher who becomes interested in Helen Trent."[5] MacLaughlin's other roles on radio included those listed in the table below.
