In his recently published volume on American economic history, Chester W. Wright says, in substance, that whereas he can give some account of the vicissitudes experienced by the several distributive factors of land, labor, and capital, he will have to deal in a very cursory fashion with the entrepreneur and with entrepreneurial gains since so little is known about them. I, for one, welcomed this statement of so eminent a student of American economic history since it gave such forthright support to ideas which I was at the time presenting to the recently organized Committee on Research in Economic History (ideas by no means wholly or even chiefly my own) relative to the desirability of research in the history of American entrepreneurship.
