Maximilian Joseph Wagenbauer, was a Bavarian artist.
After finishing school, Wagenbauer attended drawing classes in Munich, under Johann Jakob Dorner the Elder. At the turn of the 19th century he was producing mostly Neo-Classical watercolour landscapes. He served in the military from 1797 to 1801, receiving a royal artist's annuity after his service through the influence of Johann Christian von Mannlich, architect and general building director of the dukes of Zweibrücken. A condition of the royal stipend was that he produce paintings. He was appointed artist to the court and cabinet in 1802 and Inspector of the Royal Paintings Gallery in 1815. Wagenbauer focused increasingly on oil painting after 1810 and enjoyed the patronage of Maximilian I Joseph of Bavaria, who in 1811 commissioned him, Cantius Dillis and Johann Jakob Dorner the Younger to decorate the banquet hall at Schloss Nymphenburg with large paintings of Bavarian lakes.
In 1814 Wagenbauer toured Upper Bavaria. At that time he was a member of the art academies of Hanau, Berlin and Munich. Max Wagenbauer discovered numerous areas in Bavaria. Wagenbauer's works departed from the classic tradition.
