The Laplace transform of the integral of the absolute value of a real Brownian motion has been computed in 1945 by M. Kac [5], with the help of a long and subtle asymptotic analysis on Bessel functions. Up to now, there does not seem to exist a shorter proof of this well-known computa-tion. In this semi-historical note we observe that Kac’s argument could have been greatly simplified back then, had he used the eigenfunction expansion associated to a real Schrödinger operator with linear poten-tial, evaluated in 1944 (and in the same linguistic part of the world) by R.-P. Bell [2]. Résumé La transformée de Laplace de l’intégrale de la valeur absolue d’un mouvement brownien a été calculée en 1945 par M. Kac [5], à l’aide d’une longue et subti...
