Stanley T. Sigman (March 31, 1947 - December 21, 2020) was the former Chief Executive Officer of Cingular Wireless at AT&T, the United States's largest wireless provider.
A graduate of West Texas State University in Canyon, Texas, Sigman began his career with Southwestern Bell Telephone as a stockman in Hereford, Texas, in 1965.
A long-time wireless industry leader, Sigman held leadership positions at SBC Communications, where he helped start SBC's wireless business in the mid-1980s, managed its expansion into one of the largest wireless businesses in the nation, and directed its integration into BellSouth's wireless group to form Cingular Wireless in 2001.
Prior to joining Cingular, Sigman served as group president and chief operating officer for SBC Communications, responsible for the company's wireline and wholesale operations.
