The first written use of the terms ‘intrapreneur’, ‘intrapreneuring,’ and ‘intrapreneurship’ date from a 1978 white paper, Intra-Corporate Entrepreneurship, by Gifford Pinchot III and Elizabeth S. Pinchot.[5] Later Norman Macrae, who read the white paper, credited the term to Gifford Pinchot III in the April 17, 1982 issue of The Economist.[6] The first formal academic case study of corporate entrepreneurship or intrapreneurship was published in June 1982, as a Master's in Management thesis, by Howard Edward Haller, on the intrapreneurial creation of PR1ME Leasing within PR1ME Computer Inc. (from 1977 to 1981).
