Three years before NYC's 1969 Stonewall Riots, the gay liberation movement formalized in Kansas City when 40 representatives from nearly 15 organizations met on February 19-21, 1966, at Kansas City's State Hotel-formerly located at the northeast corner of 12th and Wyandotte. It was the first-ever national gathering of lesbian and gay rights activists. Missourian Harold Leland "Hal" Call spearheaded the event attended by Kansas Citians Drew Shafer, Al Greathouse, and Larry Hungerford. Other national equality visionaries Barbara Gittings, Forest Gunnison Jr, Frank Kameny, Phyllis Lyon, Del Martin, and Don Slater joined; they soon formed the 'North American Conference of Homophile Organizations' (NACHO).
