Oscar Rex (sometimes spelled Oskar; 26 March 1857 – 8 February 1929) was an Austrian genre painter.
[3] In 1881, he went to Paris to study as a student of Mihály Munkácsy, Gustave Boulanger, and Jules-Joseph Lefebvre.
[citation needed] One of Rex's works was awarded a bronze medal at the 1900 World Exhibition in Paris.
Shortly before the First World War, an exhibit of about 30 of his paintings depicting scenes from the life of Napoleon Bonaparte was displayed in 38 cities.
His grandfather, Franz Rex (1795–1855), was a native of Brno and a practicing surgeon in Prague.
