From collection Gamma Phi Beta Timeline List

Though criticism was nothing new to members of the Greek system, the turbulent Sixties was the beginning of anti-Greek sentiment that heralded brand new challenges for the coming years. For the time being, however, things were booming. A National Panhellenic Conference statistical report of June 1961 enumerated 2,008 college chapters, 4,787 alumnae chapters and a total membership that topped one million at 1,024,600 women. On top of the growth they experienced in the 1950s, Gamma Phi Beta added another 23 chapters between 1960 and 1969.
