Wer befehlen soll, muß im Befehlen Seligkeit empfinden.

On the whole, the question as to the historical possibility of entrepreneurship has not been posed. Entrepreneurship has since Schumpeter simply been assumed; translated into a kind of mechanics of leadership in modern management literature in which individual characteristics rescind behind the role expectations for managers. This is logical insofar as a theory of the entrepreneur can at best only exist in a trivial form, such as in the sense of a theory of right or wrong decisions, while the entrepreneur as an individual eludes a theoretical approach in categorical terms. So while these theoretical restrictions make a theory of the entrepreneur unattainable, typological statements can still be made about the historical phenomenon of “entrepreneurship and entrepreneurial behaviour”. This is the starting point of the following article. Characteristics, behavioural patterns and lifestyle details are extracted from entrepreneurial careers of undisputed relevance in German economic and business history between roughly 1850 and 1930: these are then brought together and generalised into an “ideal type” entrepreneur. It will become apparent that entrepreneurship is ultimately based on circumstances, preconditions and attributes which economic or decision theories can only insufficiently grasp: in fact, specific aspects of each individual personality – some of which only fully develop in the course of entrepreneurial practice – determine behaviour and these are themselves again very individual. In a certain sense, entrepreneurship represents a kind of “doer type”, a quality which calls for a whole breadth of influences which in turn cannot be deduced in economic terms.
