Bessie Wallis Warfield, (later she dropped the "Bessie"), was born on 19 June 1896 in Square Cottage, Monterey Inn, Blue Ridge Summit, Franklin County, Pennsylvania, the daughter of Teackle Wallis Warfield and Alice M. Montague. She was named after her mother's favorite aunt, Bessie, and Teackle's middle name, Wallis. The Warfields were living at Monterey Inn at that time in an attempt to cure Teackle's tuberculosis, which ended his life in November 1896, when Bessie was about five months old. Alice and Bessie were left with little to support them.
At first, Alice and Bessie moved in with Teackle's mother, Anna in Baltimore, Maryland but the two women could not get along, due either to the fact that Solomon Warfield, Wallis' bachelor uncle, had fallen in love with Alice or because Anna just didn't like Alice dating so soon after Teackle's death. So Alice and Bessie moved again, to a hotel, then yet again into the home of Alice's aunt. They soon took an apartment in a building with several other tenants. Solomon helped the two out with the majority of their expenses, but Alice also did some small at-home sewing and took a hand at cooking for some of the other tenants in the apartment building where she lived.
Wallis married Earl Winfield Spencer Jr., a member of the U.S. Navy, on 8 November 1916 at Christ Protestant Episcopal Church in Baltimore, Maryland. He was "a violent alcoholic", and she left him in 1921, though they did not divorce until 10 December 1927, when it was registered in Fauquier, Virginia.
Wallis moved to London where she married banker Ernest Aldrich Simpson on 21 July 1928 at the Chelsea Registrar's Office, Chelsea, London, England. She divorced Ernest on 27 October 1936 but not before she had begun a romantic relationship with Edward, Prince of England, heir to the throne.
England's King George died on 20 January 1936, making Edward the king. His desire to marry Wallis was objected to by the British government, as well as the British public. His famous abdication speech given on 11 December 1936 stated that, "The throne means nothing to me without Wallis beside me." Edward and Wallis were married on 3 June 1937 in Chateau de Cande, Maine-et-Loire, France, and lived thereafter in semi-exile from Britain, mostly in France, with occasional trips to Great Britain and the United States.
After his abdication, Edward was made Duke of Windsor by his brother, King George VI. Wallis was styled Duchess of Windsor but because of a new statute created just for her, she was not called "Her Royal Highness". 
Edward and Wallis were suspected during World War II to be sympathetic to the Nazis. The couple adopted a jet-setting lifestyle, living as socialites until Edward died in 1972. After his death, Wallis was rarely seen in public.
Wallis died on 24 April 1986 in Bois de Boulogne, Paris, France. She was buried next to Edward, on 29 April 1986 at Frogmore House, Windsor, Berkshire, England."
