With Rexroth acting as master of ceremonies, Allen Ginsberg, Philip Lamantia, Michael McClure, Gary Snyder, and Philip Whalen performed at the famous Six Gallery reading on October 7, 1955. Rexroth later testified as a defense witness at Ferlinghetti's obscenity trial for publishing Howl. Rexroth had previously sent Ginsberg (new in the Bay Area) to meet Snyder, and was thus responsible for their friendship. Lawrence Ferlinghetti named Rexroth as one of his own mentors.
