Adolph Schlosser was born in Leitersdorf, Austria, in 1939. He studied sculpture at the Academy of Applied Arts in Graz and from 1957 to 1959 painting at the Academy of Fine Arts in Vienna. After a period of four years in Iceland, where he combined his work as a fisherman and as a writer, he returned to Vienna. It was then that he began to practice Hörspiel (audible games) and, in the 1960s, he produced his first sculptural works.

In the mid-sixties he left Vienna and moved to Madrid, together with the sculptor Eva Lootz; he since then lived and worked in the city of Bustaviejo, Madrid. Shortly after settling in Spain, he began to channel his literary concerns towards plastic expression. After some initial incursions into geometric language, Schlosser found his own vocabulary, deeply related with nature.

In 1998 the IVAM, Valencia, dedicated its first major retrospective to him, followed by a second one organized by the Reina Sofia Museum in 2006. The artist has works installed in the following public spaces: the Palacio de la Magdalena, Santander; the RENFE Station, Santander; the Plaza Centenario, San Sebastian; the Campus of the Polytechnic University, Valencia and the Campus of the University of Torrelavega, Santander. His work can be found in many public collections, including the MNCARS, Madrid; the MACBA, Barcelona; the CAC, Seville and the CGAC, Santiago de Compostela.

Works in public collections include the Reina Sofia National Museum and Art Centre, the Museum of Contemporary Art, Barcelona, the Andalusian Centre of Contemporary Art, Seville, the Spanish Museum of Abstract Art, Cuenca, the Galician Centre of Contemporary Art, Santiago de Compostela
