Robert Vorhoelzer (13 June 1884 – 23 October 1954) was a German architect. Vorhoelzer belonged to the classical modernist school of architecture that is otherwise rather underrepresented in Bavaria. Most of his works were built when Vorhoelzer was Oberbaurat of the Bavarian postal administration. Together with Robert Poeverlein he founded the "Bayerische Postbauschule". In the early stages of his work, such as at the post office Penzberg or the post office on Ismaninger Straße in Munich, the influence of the "Heimatstil" was dominant. But later Vorhoelzer built many modern and functional buildings (post offices, depots, apartment buildings for postal staff etc.) in the style of Neue Sachlichkeit. These include, for example, the post office on Tegernseer Landstraße ("Tela-Post") in Munich-O
