Charles D. Wrege (March 11, 1924 – August 19, 2014)[1] was an American management historian, and Professor at Rutgers University.
[1] In 1952, Wrege had started his career as industrial engineer at the Weston Electric Light Company in Newark, New Jersey.
After his graduation in 1961 he moved to the Rutgers University, where he spend the rest of his academic career until his retirement in 1991.
Wrege and Perroni (1974) found out that [Taylor's] account of the loading of pig-iron has been accepted virtually without question.
[12] This organizational chart was thought lost for years, until Alfred D. Chandler Jr. had suggested its existence.
After many years of research Wrege and Guidon Sorbo Jr. (1950 - ) located one last specimen at the Library of Congress in 2005 (see image).
