Jeff Schaffer is an American writer, producer, and director born in Cleveland, Ohio.[4] A Harvard alumnus (AB '91), he began his prominent television career collaborating with comedy icons Jerry Seinfeld and Larry David, writing and producing four seasons of *Seinfeld* alongside partner Alec Berg, eventually helping run the show.[1][2] Schaffer joined *Curb Your Enthusiasm* starting in season five, serving as writer, director, and executive producer, including on episodes from 2007 to 2009 and beyond, culminating in the series finale that premiered April 7, 2024.[1][2] He co-created and executive produced the FX series *The League* with his wife Jackie, which ran for seven seasons starting in 2009, focusing on a loosely improvised fantasy football world.[1][2] Schaffer also co-created and ran *Dave* on FX, contributing as executive producer and writer.[1][3] In film, Schaffer worked on raunchy comedies, including an uncredited role on the 2004 teen film *EuroTrip*, and collaborated with Sacha Baron Cohen on *Bruno* (2009) and *The Dictator*, traveling globally for production; he also contributed to *Clear History*.[1][2] His eclectic credits blend high-profile sitcoms with hit-or-miss features, earning nominations like the 2013 Producers Guild of America Award for Outstanding Producer of Episodic Television and a 2012 Writers Guild nod.[4] Schaffer's current relevance stems from *Curb Your Enthusiasm*'s finale debrief events and his ongoing production schedule, maintaining a hectic pace across TV and film while humorously regretting self-promotion in bios.[1][3]
