This paper is in no way a definitive study of classes, especially of the business classes, in the city of Genoa in the thirteenth century. The materials for such a study do exist in the notarial archives and in earlier publications on this and related subjects. Rather, this is a report drawn from “work resumed” and work in its early stages at that.

The Dictionary of American Biography contains 1,464 biographies of eminent American businessmen. Among them are most of the wellknown financial and business figures, as well as many others never widely known or else long forgotten. The announced criterion for inclusion in the D.A.B. is that the person “did something notable in some field of American life.” Over 100 “consulting specialists” handled the various lists of candidates for inclusion; these specialists included economic and business historians.

The ensuing remarks are addressed to two topics which seem to me important: (a) what conflicts, if any, are there between business history and economic history; and (b) how can research in the two areas be mutually helpful.

The initial problems in writing the history of a business are similar to those encountered in writing the history of anything else: obtaining free access to all the existing records; determining whether these records are adequate to warrant the writing of a history; and then deciding what one wants to know from the records.

The great inventions of the past and their effect on history form a subject that everyone talks about, and no one thinks about, or precious few ever think hard about. So I consider this a good subject for economic historians to do some hard thinking about now. It is not enough just to schematize the subject philosophically; we should replace and improve some ideas of history that are very popular. Particularly in need of examination is the idea of materialistic Karl Marx, which has spread to such respectable professors and other well-heeled gentlemen that Marx would shudder at his associates—the idea that invention, technologic change, determines economic life and hence all history.

This paper is a tentative effort to suggest how some of the problems of economic history look to a student of the history of labor policy. In this, as in other areas of economic history, the investigator wants to know what the policies are and how they have worked. To help him answer these questions he has at his disposal familiar tools of inquiry—economic theory or analysis, the evidence of history, and comparative economic experience.
