Achille Etna Michallon was a French painter. Michallon studied under painters Jacques-Louis David and Pierre-Henri de Valenciennes. In 1817, Michallon won the inaugural Prix de Rome for landscape painting. He travelled to Italy in 1818 and remained there for over two years. This trip had a profound influence on his work. Before he had much time to develop what he had learned however, he died at the age of 25 of pneumonia.
