Abstract Today the concept of "potential flow" is too often associated, wrongly, with the notion of ideal, hence inviscid fluid. Herein the original development of Joseph-Louis LAGRANGE is presented. He introduced the velocity potential for real fluid flows, provided that the resultant of the forces derives from a potential. In the same article, LAGRANGE also presented the concept of stream function and the equation of the celerity of a small disturbance in shallow-water. LAGRANGE made an outstanding contribution in 1781 and he was truly ahead of his time.
