Mason Locke Weems (October 11, 1759 – May 23, 1825), usually referred to as Parson Weems, was an American book agent and author who wrote the first biography of George Washington immediately after his death. He was the source of some of the apocryphal stories about Washington. The tale of the cherry tree ("I cannot tell a lie, I did it with my little hatchet") is included in the fifth edition of The Life of Washington
(1809 imprint, originally published 1800), a bestseller that depicted Washington's virtues and was intended to provide a morally instructive tale for the youth of the young nation.
Mason Weems was born on October 11, 1759, in Anne Arundel County, Maryland. He studied theology in London and was ordained in the Protestant Episcopal Church in 1784. He worked as a minister in Maryland in various capacities from 1784 to 1792. Financial hardship forced Weems to seek additional employment, and he began working as a traveling book agent. Weems married Frances Ewell in 1795 and established a household in Dumfries, Virginia. He had a small bookstore in Dumfries that now houses the Weems–Botts Museum, but he continued to travel extensively, selling books and preaching.
After the death of his father-in-law, Colonel Jessie Ewell (1743–1805), Weems assumed the Ewell family estate, Bel Air, located in Prince William County, Virginia, to partially satisfy debts owed to Weems. In 1808, Weems and his family moved into Bel Air, where he lived until his death. While on travel in Beaufort, South Carolina, Weems died on May 23, 1825 of unspecified causes. He is buried at Bel Air.
