published first published its magazine, the Sigma Kappa Triangle, in 1907. In 1918, the sorority adopted the Maine Sea Coast Missionary Society as its first philanthropy interest. Its second philanthropy, begun in the aftermath of WWII in 1946 had an international focus, supporting the American Farm School of Thessaloniki, Greece. Its mission complete, the Farm School effort has been discontinued. In 1924 Sigma Kappa established its first national headquarters in Reading, Massachusetts, which would move to Indianapolis, Indiana, in 1936. In 1937, it began sending out field consultants for collegiate chapters. In 1954, Sigma Kappa adopted gerontology as its third and most extensive philanthropy, which continues to the present day. In 1959, the sorority absorbed another NPC social sorority, Pi Kappa Sigma, which had been formed in 1894 at Michigan State Normal College (Now Eastern Michigan University). In 1962, it established a separate branch, the Sigma Kappa Foundation, to manage its philanthropy funds, and added Alzheimer's disease as a focus for its gerontology philanthropy in 1984. In 1992, it began another program as part of its gerontology initiatives, "Inherit the Earth". In 1993, Sigma Kappa established a housing corporation.
