Born in Paris in 1870.
The artist Henri Riviere became Ott’s first art teacher who infected him with a passion for Paul Gauguin’s works and Japanese engravings. Under the influence of Riviere, Ott went to Brittany in 1889 in Gauguin’s wake.
After his return to Paris in the late 1890s, Ott’s style drew close to that of the graphic artists of the School of Montmartre and the Nabis group.
Between 1901 and 1914 Ott regularly contributed to the Salon des Independants.
After taking part in military operations during WWI, Ott abandoned art.
He died in Villeneuve-Saint-Georges (France) in 1927.
