## History

In 1949, Henry Taub founded Automatic Payrolls, Inc. as a manual payroll processing business with his brother Joe Taub. Frank Lautenberg joined the brothers in the company's infancy. In 1957, Lautenberg, after successfully serving in sales and marketing, became a full-fledged partner with the two brothers. In 1961, the company changed its name to Automatic Data Processing, Inc. (ADP), and began using punched card machines, check printing machines, and mainframe computers. ADP went public in 1961 with 300 clients, 125 employees, and revenues of approximately US$400,000. The company established a subsidiary in the United Kingdom in 1965. In 1970, Lautenberg was noted as being the president of the company. Also in 1970, the company's stock transitioned from trading on American Stock Exchange to trading on the New York Stock Exchange. Lautenberg continued in his roles as chairman and CEO until elected to the United States Senate from New Jersey in 1982.
From 1985 onward, ADP's annual revenues exceeded the $1 billion mark, with paychecks processed for about 20% of the U.S. workforce. In the 1990s, ADP began acting as a professional employer organization (PEO) making several related acquisitions.
On October 21, 2008, ADP switched its stock listing to the NASDAQ Global Select Market.
