Bio	Arthur Charles Nielsen, Sr. was an American market analyst who founded the ACNielsen company. Arthur Charles Nielsen was born in Chicago, Illinois. He was of Danish descent. Nielsen was educated at University of Wisconsin (now University of Wisconsin–Madison), where he received a B.S., summa cum laude in 1918. He was a member of Tau Beta Pi (engineering honor society), the Sigma Phi Society and a captain of the varsity tennis team from 1916 to 1918. He subsequently served in U.S. Naval Reserve. With his son Arthur Nielsen, Jr., he won the U.S. Father and Son doubles tennis titles in 1946 and 1948. The University of Wisconsin awarded him an honorary Doctor of Science (ScD) in 1974. Nielsen was appointed a Knight of the Order of the Dannebrog, Ridder af Dannebrog (1961) by the nation of Denmark. Nielsen and his wife Gertrude (d.1998) donated the Nielsen Tennis Stadium to the University of Wisconsin–Madison. In 1990, the A.C. Nielsen family made a donation to UW-Madison to create a full-time MBA program specializing in market research. It is the only full-time market research program in the United States. A small tennis center in Winnetka, Illinois is named after him. Nielsen worked as an electrical engineer for the Isko Company in Chicago from 1919 to 1920 and for the H. P. Gould Company in Chicago from 1920 to 1923. He founded the ACNielsen company in 1923, and in doing so advanced the new field of market research. This involved: (1.) test marketing new products to determine their viability prior to costly mass marketing and production; and (2.) measuring product sales at a random sample of stores to determine market share. Careful statistical sampling was crucial to this process. The techniques developed by Nielsen were especially important for the efficient operation of a market prior to the introduction of computerized digital networks that in the 1990s enabled continuous and comprehensive monitoring of sales by product retailers. Nielsen was also a pioneer in developing methods of measuring the audience of radio and television broadcasting programs, most notably the Nielsen ratings. Nielsen inaugurated a National Radio Index for broadcasters and advertisers in 1942, followed by a television ratings service in 1950. By the time of his death, the company's revenue was US$398 million annually. He was elected to the International Tennis Hall of Fame in 1971 for his contributions to the sport.
