On "Seinfeld", what is the Soup Nazi's real name, as revealed by Elaine?

On “Seinfeld,” the Soup Nazi’s real name is Yev Kassem. The name is revealed in the series finale, when the soup vendor testifies about Elaine’s role in ruining his business and forcing him to leave for Argentina.

Yev Kassem is played by Larry Thomas in the season-seven episode “The Soup Nazi,” which first aired on November 2, 1995. The character’s strict ordering rules and catchphrase “No soup for you!” made him one of the sitcom’s most recognizable guest characters.

The character was inspired by Al Yeganeh, the Iranian-American owner of Soup Kitchen International in New York City. Yeganeh was known for excellent soup and an exacting customer-service style, although the fictional character’s name and behavior were created for the show.

A common mix-up is confusing Yev Kassem with Al Yeganeh, the real vendor who inspired the character. Kassem is the fictional Seinfeld name; Yeganeh is the real-life inspiration.
