The nature of boundary conditions in hydrodynamics was widely debated in the nineteenth century, and many of the great names in fluid dynamics have expressed an opinion on the subject, as discussed in a recent review. The linear slip boundary condition was introduced by Navier, and this remains a standard characteristic of the slip used today. Helmholtz and von Piotrowski were probably the first to report some evidence of slippage at the solid-liquid interface. We refer the reader to a comprehensive review for detailed accounts of early experimental work. The significance of hydrophobicity for the slip phenomenon does not seem to be recognized at this early stage.
