Peter Lassally's professional journey began in the 1970s, serving as the trusted associate producer for the iconic "The Tonight Show" under the esteemed guidance of Johnny Carson.
As his career progressed, Lassally rose through the ranks, eventually becoming an Executive Producer alongside Fred De Cordova by 1992.
When Carson's legendary tenure came to a close in 1992, Lassally seized the opportunity to join forces with David Letterman, co-owning the NBC nighttime show "Late Night" alongside Carson Productions.
In a bold move, Lassally accompanied Letterman to CBS, where they launched the "Late Show" in 1993.
However, Lassally's tenure as Executive Producer of the "Late Show" came to an end, as he was succeeded by the talented Rob Burnett, a skilled writer for the show.
