In the 1920s, French painter Luc-Albert Moreau created a suite of 60 lithographs of the many aspects of boxing, which he considered a noble sport. Physiologie de la Boxe featured paintings and drawings of boxing winners and losers, as well as spectators and managers.
Moreau was a painter with the Cubists up to 1912, but soon reverted to a more traditional style. He also produced lithographs of Parisian bars, restaurants, nightclubs, music halls, brothels and circuses, which revealed a comprehensive knowledge of the lively Paris underworld, including the gay and lesbian scene. After World War I, Moreau lived with the violinist Hélène Jourdan-Morhange, the widow of the painter Jacques Jourdan, who had been killed in the war. The couple were close friends with the famous composer Maurice Ravel.
