Class of 1973
After earning a degree in speech therapy, Leno got his start in comedy by performing in nightclubs as he toured the country. In the mid-1980s, he began appearing on late-night TV, and eventually became a guest host on "The Tonight Show." He beat out David Letterman for the host position when Johnny Carson retired in 1992, and has been running the show ever since.
