Ivory towers? The commercial activity of British professors of engineering and physics, 1880–1914.

The involvement of British academic scientists in commercial work has been often discussed by historians of science and technology. However a systematic study of this activity is still lacking. Focussing on the period 1880 to 1914, I examine the engagement in consulting, patenting and entrepreneurial initiatives of a segment of that community, namely engineering and physics professors. I discuss the institutional context in which it occurred and their motivations. The survey highlights that the majority of the engineering professors examined were involved in consulting and patenting, and a significant number of them pursued also entrepreneurial activities. As for the physics professors, only a few followed the example of their engineering colleagues, but did so vigorously. I argue that far from being reluctantly brought into the market for knowledge, the engineering as well as the physics professors who engaged these extra-academic activities eagerly sought to partake in the commercialization of the products of their scientific work
