An only child, Bessie Wallis (sometimes written "Bessiewallis") Warfield was born in Square Cottage at Monterey Inn, a hotel directly across the road from the Monterey Country Club, in Blue Ridge Summit, Pennsylvania. A summer resort close to the Maryland-Pennsylvania border, Blue Ridge Summit was popular with Baltimoreans escaping the season's heat, and Monterey Inn, which had a central building as well as individual wooden cottages, was the town's largest hotel. Her father was Teackle Wallis Warfield, the fifth and youngest son of Henry Mactier Warfield, a flour merchant described as "one of the best known and personally one of the most popular citizens of Baltimore" who ran for mayor in 1875.

In April 1916, Wallis met Earl Winfield Spencer Jr., a U.S. Navy aviator, at Pensacola, Florida, while visiting her cousin Corinne Mustin. It was at this time that Wallis witnessed two airplane crashes about two weeks apart, resulting in a lifelong fear of flying. The couple married on 8 November 1916 at Christ Episcopal Church in Baltimore, which had been Wallis's parish. Win, as her husband was known, was a heavy drinker. He drank even before flying and once crashed into the sea, but escaped almost unharmed. After the United States entered the First World War in 1917, Spencer was posted to San Diego as the first commanding officer of a training base in Coronado, known as Naval Air Station North Island; they remained there until 1921.  In 1920, Edward, the Prince of Wales, visited San Diego, but he and Wallis did not meet. Later that year, Spencer left his wife for a period of four months, but in the spring of 1921 they were reunited in Washington, D.C., where Spencer had been posted. They soon separated again, and in 1922, when Spencer was posted to the Far East as commander of the Pampanga, Wallis remained behind, continuing an affair with an Argentine diplomat, Felipe de Espil. In January 1924, she visited Paris with her recently widowed cousin Corinne Mustin, before sailing to the Far East aboard a troop carrier, USS Chaumont (AP-5). The Spencers were briefly reunited until she fell ill, after which she returned to Hong Kong.  Wallis toured China, and while in Beijing stayed with Katherine and Herman Rogers, who were to remain her long-term friends. According to the wife of one of Win's fellow officers, Mrs Milton E. Miles, in Beijing Wallis met Count Galeazzo Ciano, later Mussolini's son-in-law and Foreign Minister, had an affair with him, and became pregnant, leading to a botched abortion that left her infertile. The rumour was later widespread but never substantiated and Ciano's wife, Edda Mussolini, denied it. The existence of an official "China dossier" (detailing the supposed sexual and criminal exploits of Wallis in China) is denied by most historians and biographers. Wallis spent over a year in China, during which time--according to the socialite Madame Wellington Koo--she only managed to master one Chinese phrase: "Boy, pass me the champagne". By September 1925, she and her husband were back in the United States, though living apart. Their divorce was finalised on 10 December 1927.  By the time her marriage to Spencer was dissolved, Wallis had become involved with Ernest Aldrich Simpson, an Anglo-American shipping executive and former officer in the Coldstream Guards. He divorced his first wife, Dorothea (by whom he had a daughter, Audrey), to marry Wallis on 21 July 1928 at the Register Office in Chelsea, London. Wallis had telegraphed her acceptance of his proposal from Cannes where she was staying with her friends, Mr and Mrs Rogers.  The Simpsons temporarily set up home in a furnished house with four servants in Mayfair. In 1929, Wallis sailed back to the United States to visit her sick mother, who had married legal clerk Charles Gordon Allen after the death of Rasin. During the trip, Wallis's investments were wiped out in the Wall Street Crash, and her mother died penniless on 2 November 1929. Wallis returned to England and with the shipping business still buoyant, the Simpsons moved into a large flat with a staff of servants.  Through a friend, Consuelo Thaw, Wallis met Consuelo's sister Thelma, Lady Furness, the then-mistress of Edward, Prince of Wales. On 10 January 1931, Lady Furness introduced Wallis to the Prince at Burrough Court, near Melton Mowbray. The Prince was the eldest son of King George V and Queen Mary, and heir apparent to the British throne. Between 1931 and 1934, he met the Simpsons at various house parties, and Wallis was presented at court. Ernest was beginning to encounter financial difficulties, as the Simpsons were living beyond their means, and they had to fire a succession of staff.  In January 1934, while Lady Furness was away in New York City, Wallis allegedly became the Prince's mistress. Edward denied this to his father, despite his staff seeing them in bed together as well as "evidence of a physical sexual act". Wallis soon ousted Lady Furness, and the Prince distanced himself from a former lover and confidante, the Anglo-American textile heiress Freda Dudley Ward.  By the end of 1934, Edward was irretrievably besotted with Wallis, finding her domineering manner and abrasive irreverence toward his position appealing; in the words of his official biographer, he became "slavishly dependent" on her. According to Wallis, it was during a cruise on Lord Moyne's private yacht Rosaura in August 1934 that she fell in love with Edward. At an evening party in Buckingham Palace, he introduced her to his mother--his father was outraged, primarily on account of her marital history, as divorced people were generally excluded from court. Edward showered Wallis with money and jewels, and in February 1935, and again later in the year, he holidayed with her in Europe. His courtiers became increasingly alarmed as the affair began to interfere with his official duties.  In 1935, the head of the Metropolitan Police Special Branch told the Metropolitan Police Commissioner that Wallis was also having an affair with Guy Marcus Trundle, who was "said to be employed by the Ford Motor Company". Claims of an affair were doubted, however, by Captain Val Bailey, who knew Trundle well and whose mother had an affair with Trundle for nearly two decades, and by historian Susan Williams.
