Evelyn Knight
Evelyn Dawn Knight (born November 5, 1942) is an English woman known for her involvement in the Abscam sting operation of the 1970s, with her ex-husband Mel Weinberg. A character inspired by her was portrayed on film by Amy Adams in American Hustle (2013) for which Adams was nominated for the Academy Award for Best Actress. The story of Abscam was depicted as well in the 1981 book The Sting Man by Robert Greene.

Personal life
Knight was born in Watford, the daughter of Ethel (née Wilson) and Sidney Knight. Her father was the manager of a crumpet factory.

Knight emigrated to the United States in 1967, when she was in her late twenties. At a party on Long Island sponsored by the British government, she met Mel Weinberg, a Jewish businessman 17 years her senior, and the two began a long love affair. Weinberg was married to his second wife, Marie, at the time. Marie committed suicide in 1982 at age 58. She had confronted Knight about the affair after she learned that Knight was living nearby in a house being paid for by Weinberg. Soon after Marie's death, Knight and Weinberg married.

Abscam
Weinberg began involving Evelyn in his cons, using her as a ploy to conduct business. He would introduce her as Lady Evelyn Knight, one of the world's richest women. The two were arrested in 1977 on charges of fraud and conspiracy. They made a plea-deal with the FBI to help them in the investigation of Abscam, and in return their charges would be dropped for probation.

Later life
Knight kept out of the spotlight once the Abscam era ended, and moved to Florida with her husband Mel. They divorced in 1998, but still lived near each other until his death in 2018. Knight found work at NASA, where she took care of animals used in space experiments.
