He had joined the drama club in high school as a way to meet girls after quitting the football team as an offensive end after just one game (he didn't like pain from tackling).

The first episode of M*A*S*H airs on CBS, entitled “M*A*S*H Pilot". Larry was cast in the role of Major Frank Burns, a character he would be forever linked with and identified by. In an interview, Linville says he based his portrayal of Burns on “every idiot I’ve ever known.” "The days on set were often 12-15 hours long and the pressure was very intense. However, the show was such a success because the cast "wasn't held together by teamwork," he said. They were held together by 'human chemistry.'" You can find an article about his home life here, an article about being on the show, here, and an article about his character, Frank, here.

Approximately 30 friends and family were in attendence and the reception was held on a yacht, where 150 guests sailed the San Pedro harbor for 2 hours. Article states that the couple was to go on a 2 month honeymoon. No M*A*S*H co-stars attended the wedding or reception. According to People Magazine, they "dropped the word 'obey' from their vows.

It is very probable that Larry began doing college visits and lectures before '84, but the earliest listing I could find was for this year. You can see an incomplete list here. An 1987 article mentions his wife Melissa accompanied him on all of his campus visits, but he was married to Susan at the time the article was published. Either the article's author was using old information or it was an unfortunate typo! You can see a list of schools he visited here. Larry's father, Harry also died this year, date unknown.
After 2 1/2 years of marriage, Larry and Melissa divorce. He marries again about a year later.

After about a 5 year marriage, divorces Susan Hagan. According to People Magazine, "Linville went through a bitter divorce from his fourth wife. That meant the shedding of his Hollywood trappings: 'I dumped the whole damn thing—the house, the terraced yard, the swimming pool, the hot tub, the gardener and the pool man.' Now he lives with his cat, Mad Max, in a condo in Arcadia, Calif., and works mainly on the Canadian stage. Linville's income is stretched by his M*A *S*H residuals ('just about enough to pay my car insurance'). He has no regrets over Leaving the show.
