Made from what was known as the King Ubu Gallery ("an all poet thing"), in 1954, Hedrick co-founded The Six Gallery in San Francisco, California with David Simpson, Hayward King, John Allen Ryan, Deborah Remington and Jack Spicer—and by 1955, had "become the official director". Although "the activities of the "6" were poorly documented", the Six Gallery functioned as an underground art gallery for the members and a meeting place for poets and literati alike. "The Six" was a focal point for countercultural activity during a crucial transition point—unconventional artists were deep underground—partly because no audience encouraged them to emerge, partly because it was safer there. "The Six" delighted at the chance to defy authority. As the gallery director, Hedrick organized and participated in the spontaneous exhibition/poetry reading/performance events that were the precursors of the 'Happenings' of the 1960s.
