When did Administrative Professionals Day begin?

Administrative Professionals Day/Week was originally organized in 1952 as "National Secretaries Week" by the National Secretaries Association (now known as the International Association of Administrative Professionals) in conjunction with public relations executive Harry Klemfuss and a consortium of office product manufacturers. It was established as an effort to recognize secretaries for their contributions in the workplace, and to attract people to secretarial/administrative careers.

The association successfully campaigned U.S. Secretary of Commerce Charles Sawyer to proclaim the first National Secretaries Week on June 1-7, 1952. He designated Wednesday, June 4, as National Secretaries Day. Sawyer, Barrett and Woodbridge participated in ceremonies held in Washington, D.C.
