found: Wikipedia, 29 May 2015:under Jules Regnault (Jules Augustin Frédéric Regnault; born 1 February 1834 in Béthencourt, dies 9 December 1894 in Paris; a French economist who first suggested a modern theory of stock price changes in "Calcul des chances et philosophie de la Bourse" (1863); he is one of the first authors who tried to create a 'stock exchange science' based on statistical and probabilistic analysis; there is a mistake in the "Grand dictionnaire universel du XIXe siècle" published by Pierre Larousse: in the Jules Regnault bibliographical note, he wrote "Regnault (Jules), French learned, dead in 1866"; this note attributes several books to Jules; however, with the exception of the "Calcul des chances et philosophie de la bourse", all the other books were written by Jean-Joseph Regnault (1797-1863) who signed some of his books 'J. Regnault')
