From 1898 to 1902 he studied at the academy of arts in Munich under Johann Herterich, Ludwig von Herterich, Carl von Marr and Peter von Halm. This was followed by work stays in Budapest, Dresden and Berlin – study trips also took him to Italy and Albania.
In 1914 he returned to Vienna and in 1922 became an honorary member of the Hagenbund. In the spring exhibition of the same year some of his works were shown – however the press reacted with irritation to his hypermodernist style. Reinitz was geared to Cubism as well as to the Neue Sachlichkeit – a wide range of colors and the play with light and shadow were characteristic of his images.
With the exception of the Hagenbund exhibitions Reinitz used a very retired life, which is why few details about his biography are known. Apparently plagued by self-doubt and depressions, the artist died on 25 September 1935 in Vienna.
