William Post (Bill) was Emily Post’s only grandchild, and he was the husband of Elizabeth Post (Libby), who took over as the spokesperson and author for The Emily Post Institute in 1965.

Born on July 4, 1921, in New York City, Bill was close to his famous grandmother and often spent summers with her at her home in Edgartown on Martha’s Vineyard. He attended St. Paul’s School and MIT, from which he graduated in 1942. He spent the World War II years in the Special Devices Division of the Navy in Washington, D.C., designing technical equipment for various classes of Navy ships. Bill married Elizabeth Lindley Cookman in August, 1944. Bill and Libby shared a wonderful sixty-six years of marriage, during which they raised four children, Allen Post; Bill Post, Jr.; Cindy Post Senning; and Peter Post. They lived in a variety of places including Washington, D.C.; Bogota, Colombia; Edgartown, Massachusetts; Rye, New York; Stowe, Vermont; Marathon, Florida; Naples, Florida; and finally Bill lived in Shelburne, Vermont. Everywhere they went, Bill and Libby made many friends who shared their love of golf, fishing, travel, entertaining, and gracious living.

While in Rye, New York, during the 1950s until 1974, with his partner Dick Maulsby, Bill founded and ran the Hobbs Equipment Company, a successful truck equipment business. Together with Libby, Bill managed The Emily Post Institute after the death of his grandmother, Emily Post, in 1960, until 1995. Bill was an avid golfer, an expert fisherman, a skillful and talented woodworker, and a lifelong pilot who flew his Luscombe airplane around the United States at the age of 19, when flying was still in its infancy and something of a novelty. William Post was a wise, kind, thoughtful, and extremely considerate person, who set a wonderful example for his children and grandchildren, and who was admired and loved by everyone who knew him—a true gentleman.
