Marcel Hastir (22 March 1906 – 2 July 2011), was an artist, theosophist and member of the Belgian Resistance during World War II. He lived from 1935 onwards at 51 Rue du Commerce, Brussels, which is also where he set up his studio. From the outset, it was a place where young musicians came to perform. Today there are two prizes bearing his name which are awarded by the Académie Royale de Belgique (Belgian Royal Academy), one for music and one for painting.
