Early collector of Egon Schiele, wrote a memoir of the artist. Benesch was a railroad administrator in Vienna for the southern line. Although the position was not a particularly lucrative one, he collected contemporary Austrian art. Early on he befriended the Austrian expressionist artist Egon Schiele and became one of his earliest patrons. Schiele painted a combined portrait of him and his son in 1913 (Doppelbildnis H. Benesch und Sohn, Neue Galerie der Stadt Linz, Wolfgang Gurlitt Museum, Inventory 12). In 1943, after his son's exile, Benesch wrote a brief memoir of his experience with Schiele. Benesch's son was an eminent art historian Otto Benesch, whose wife published the manuscript in 1965.
