James Edward Day (October 11, 1914 – October 29, 1996) was an American lawyer and business executive, most widely known as the United States Postmaster General under whose leadership the ZIP code was introduced.
During his time at the job the Dag Hammarskjöld invert stamp was printed and reprinted. In August 1963, he resigned as Postmaster General, saying it was hard to live on the $25,000 salary the office paid.[3] In 1965 he published a light-hearted memoir about his Postmaster General service, My Appointed Round: 929 days as Postmaster General (New York: Holt, Rinehart and Winston, LCCN65-14437).
Return to private practice
Immediately after leaving the federal government, Day returned to private law practice and joined the firm of Sidley Austin Burgess and Smith. In this capacity he helped establish the firm's Washington, DC office.[4] His clients included the Advertising Mail Marketing Association, an organization that particularly benefited from the ZIP code's use in targeting mass marketing campaigns by income level.[3]
Day's departure resulted from a perceived slight by his partners following the merger of Sidley with the Chicago law firm Liebman, Williams, Bennett, Baird and Minow.[citation needed] Day sued his former partners in a case that went to the United States Court of Appeals for the District of Columbia Circuit. Day v. Sidley & Austin, 548 F.2d 1018 (D.C.Cir. 1976). The court found that Day suffered from a bruised ego but that the facts failed to establish a legal cause of action.[citation needed] Day joined Squire, Sanders & Dempsey in 1973, where he remained until he retired in 1984.[1] Day also served as legal counsel for the Association of Postal Commerce for a number of years until 1986; the association subsequently established the annual "J. Edward Day Award", given in recognition of "distinguished service to the nation's postal community."[5]
