SPS National History
As explained on the official SPS website:
"The Society of Physics Students was formed in 1968 with a constitution that combined its two "parent" organizations, The AIP Student Sections and the Sigma Pi Sigma honor society. SPS now has over 700 chapters on campuses across the country. About 5,000 students take part in chapter activities each year, making SPS the fourth largest physics society in the country. The associated honor society, Sigma Pi Sigma, now exists in about 450 of those chapters with over 75,000 inductees throughout its history." (http://www.spsnational.org/about/)
