Wilbur Daigh Mills (May 24, 1909 – May 2, 1992) was an American Democratic politician who represented Arkansas's 2nd congressional district in the United States House of Representatives from 1939 until his retirement in 1977.
As chairman of the House Ways and Means Committee from 1958 to 1974, he was often called "the most powerful man in Washington."
Born in Kensett, Arkansas, Mills pursued a legal career and helped run his father's bank after graduating from Harvard Law School.
He served as the county judge of White County, Arkansas before winning election to the United States House of Representatives in 1938.
As Chairman of the Ways and Means Committee, Mills played a large role in the establishment of Medicare.
He also helped pass the Tax Reform Act of 1969, which created the alternative minimum tax.
Mills ran for president in 1972, championing an automatic Cost of Living adjustment to Social Security, but he performed poorly in the Democratic primaries.
After two public incidents with a stripper named Fanne Foxe, he declined to seek re-election in 1976.
After leaving office, he returned to the practice of law and helped establish a center for the treatment of alcoholism.
