The national Anthropos is an organized male affiliate group of the National Sorority of Phi Delta Kappa, Incorporated. Its membership consists of spouses, brothers, sons, and male friends of active members of the Sorority.

In 1975, Supreme Basileus Arthur Mae Norris revived and reorganized the “Men in Our Lives”.  The reorganization took place in Jacksonville, Florida in 1975.  Later, Supreme Basileus Norris recommended to the 1977 conclave assembly that the “Men in Our Lives” would become organized as a National affiliate.  The Conclave delegates approved the recommendation.  The official name was changed to the “Anthropos”—simply referring to the “males”.  A total of 147 Anthropos attended the 1977 Conclave in Dallas, Texas.  The National Anthropos became fully operational under their new name in July 1977, the first year of newly elected Supreme Basileus Billy J. Mason’s administration.
