Abstract

The famous French chemist, Marcelin Berthelot, published his first scientific paper in 1850. However, reference to this paper has been largely ignored in the various accounts of his lasting contributions to chemistry. The probable reason for this is that this paper is concerned with a method of subjecting a liquid to tension, and it is more appropriate to regard it as a paper on physics rather than on chemistry. In the work described in this largely-forgotten paper, written whilst he was still a young research student, Berthelot showed that liquids contained in his ‘Berthelot tube’ could withstand a considerable tension; and he is the first person to have observed cavitation, a phenomenon which has been studied so widely this century. The next mention in the literature of the Berthelot tube method is at the turn of the present century, after which it again seems to have been forgotten until the 1940s; since then there has been considerable progress using the Berthelot tube technique. In this paper the work described in Berthelot's original paper is discussed in some detail, and the subsequent fruitful development of the method is also traced and assessed
