Keith Rockwell opened the Purple Onion in 1952, tucking it beneath the street level on Columbus Avenue between Jackson and Pacific in the heart of North Beach. His sister Virginia "Ginnie" Steinhoff and her husband Irving "Bud" Steinhoff began working weekends at the club and took over management in 1960. Bud ran the Purple Onion until his death in November 1983; Ginnie continued until 1989. The club's intimate setting -- 80 seats in an underground room during the Beat era -- made it an incubator for performers who needed a small, forgiving space to develop. It was the anti-arena: a place where a comedian's whisper carried to the back wall, and where failure happened at conversational distance.

The list of careers that passed through the Purple Onion in its first two decades is staggering. Bob Newhart, Lenny Bruce, and Woody Allen performed on its tiny stage. The Kingston Trio and Jim Nabors got their starts there. The Smothers Brothers titled their first album The Smothers Brothers at the Purple Onion -- though only the introduction was actually recorded in the club. The Irish Rovers played the room. Phyllis Diller's 1955 debut became the most celebrated origin story in the club's history: a housewife who had never done stand-up walking into an 80-seat cellar and walking out, eventually, as one of the most famous comedians in America. The Purple Onion did not just host talent. It manufactured confidence.

After the Steinhoffs departed, the club reinvented itself. Tom Guido became manager in 1993 and transformed the Purple Onion into the epicenter of San Francisco's garage rock scene, booking the Rip Offs, the Trashwomen, Brian Jonestown Massacre, Guitar Wolf, and the 5.6.7.8's. The club closed in 1999 and Guido died in 2019. When it reopened for comedy in 2004, Robin Williams turned up for weekly comedy nights alongside Paul Krassner and Mort Sahl. Shows by Zach Galifianakis, Margaret Cho, and Greg Proops filled the room past its 80-person capacity, sometimes squeezing in 110 people. The Purple Onion proved adaptable enough to thrive across entirely different eras of entertainment.

The Purple Onion has closed and reopened so many times it has become a kind of underground phoenix. The building was sold in 2012 "with no plans to rescue." It came back as Doc's Lab in 2014, hosting music and comedy until closing again in 2018. The name migrated briefly to "The Purple Onion at Kell's" around the corner on Jackson Street. In 2022, the original basement reopened as Lyon & Swan, a high-end restaurant with live entertainment, which lasted eleven months. Each incarnation has tried to capture the magic of the cellar's original decades, when 80 seats underground on Columbus Avenue were enough to launch careers that would fill theaters and television screens across the country. The space keeps calling people back, as if the basement itself remembers what it once was.
