Piech was born in Brooklyn, New York in 1920. He studied at the Cooper Union College of Art and in 1937 trained as a graphic artist at Dorlands Advertising Agency. During the Second World War Piech was posted to Britain with the US Eighth Army Air Force. After the war he studied printmaking at Chelsea College of Art and was appointed as the artistic director of W. S. Crawford and Service advertising agencies, where he worked from 1951 to 1968. After a successful commercial career as a graphic designer, Piech went freelance in 1968 having already established his own firm the Taurus Press in 1959. During this period he produced linocut and woodcut printed posters, illustrations and limited edition books for a variety of clients and exhibition opportunities. From the early 1970s he taught at various art schools whilst creating and exhibiting vast numbers of political and socially motivated printed posters, many of which combined his trademark hard-hitting imagery with heavy cut linocut lettering. Piech spent the last ten years of his life living in Porthcawl, South Wales, where he continued to work and had an influential impact on the Welsh art scene. He died in Porthcawl, Mid-Glamorgan, Wales in 1996.
