IN: Carl Dean Switzer (August 8, 1927 - January 21, 1959) was an American singer, child actor, breeder and guide. Switzer began his career as a child actor in the mid-1930s appearing in the Our Gang short subjects series as Alfalfa, one of the series' most popular and best-remembered characters. After leaving the series in 1940, Switzer struggled to find substantial roles owing to typecasting. As an adult, he appeared mainly in bit parts and B-movies.

In early 1954, Switzer went on a blind date with Diantha (Dian) Collingwood, heiress of grain elevator empire Collingwood Grain. Collingwood had moved with her mother and sister to California in 1953 because her sister wanted to become an actress. Switzer and Collingwood got along well and married in Las Vegas three months later. In 1956, with his money running out and Diantha pregnant, his mother-in-law offered them a farm near Pretty Prairie, Kansas, west of Wichita. Their son, Justin Lance Collingwood Switzer (now Eldridge), was born that year. They divorced in 1957.  In 1987, former Our Gang co-star George "Spanky" McFarland recalled a meeting with Switzer when they spoke about the farm:  The last time I saw Carl was 1957. It was a tough time for me--and him. I was starting a tour of theme parks and county fairs in the Midwest. Carl had married this girl whose father owned a pretty good size farm near Wichita. When I came through town, he heard about it and called. He told me he was helping to run the farm, but he finally had to put a radio on the tractor while he was out there plowing. Knowing Carl, I knew that wasn't going to last. He may have come from Paris, Illinois, but he wasn't a farmer! We hadn't seen each other since we left the 'Gang.' So we had lunch. We talked about all the things you'd expect. And then I never saw him again. He looked pretty much the same. He was just Carl Switzer--kind of cocky, a little antsy--and I thought to myself he hadn't changed that much. He still talked big. He just grew up.  In January 1958 Switzer was getting into his car in front of a bar in Studio City, when a bullet smashed through the window and struck him in the upper right arm. The gunman was never caught. That December he was arrested in Sequoia National Forest for cutting down 15 pine trees; he was sentenced to a year's probation and ordered to pay a $225 fine.
