Thaddeus Vincenty (born Tadeusz Szpila; 27 October 1920 – 6 March 2002) was a Polish American geodesist who worked with the U.S. Air Force and later the National Geodetic Survey to adapt three-dimensional adjustment techniques to NAD 83. He is best known for Vincenty's formulae, a geodesic calculation technique published in 1975 and known for its accuracy—about one-half millimeter.
Vincenty's studies were interrupted by World War II, and he eventually arrived in a displaced persons camp. He arrived in the United States in 1947, and took his father's first name as his surname. Within months, he enlisted in the Air Force, and only became involved in computer programming and surveying in 1957. After studying via correspondence courses, he published his first research paper in 1963. After 30 years in the Air Force, he left Cheyenne, Wyoming, and took a position at National Geodetic Survey.
His contributions to the NAD 83 include the introduction of three dimensional Earth centered coordinates, which unifies locations on Earth with locations in space, an essential development for GPS.
Vincenty received the Department of Commerce Medal for Meritorious Service in 1982.
Vincenty and his wife Barbara had one daughter, two sons, and three grandchildren at the time of his death.
