Résumé : I present a review of the study of optical phenomena in moving bodies during the 19th century. I show how Lorentz's progressive stages approach successfully explained these phenomena and how he finally got his relativistic formulae. The important role of H. Poincaré as a critic reviewer of existent theory is underlined. I discuss with some details the Poincaré's distant clocks synchronisation, which clarifies the meaning of Lorentz's local time.
