Maximilian Weishaupt was born in 1949 in Schwendi, Germany. At the age of 17 he attended an exhibition of works by German artist Günter Fruhtrunk in Munich, Germany. This visit deepened his interest in art, particularly of works belonging to the Concrete Art movement in which a strong emphasis is placed on the sensuous experience of shape and colour.
Upon graduation in 1977 with a degree in architecture, Weishaupt returned to his first passion and worked as a freelance artist, creating many paintings, prints, and sculptures until 1982 when he put his paintbrushes aside, working as an architect henceforth and focusing on collecting art. He and his wife Agathe, as patrons, amassed a well-founded collection of art by international artists, focusing on Concrete Art, until he passed in 2018.
