Ger van Elk (1941– 2014, Amsterdam, NL) is considered to be one of the pioneers of conceptual art. Averse to conventions, Van Elk experimented with many different media and frequently collaborated with fellow artists. In 1969 he participated in the groundbreaking exhibitions When Attitudes Become Form at Kunsthalle Bern and Op Losse Schroeven: Situaties en Cryptostructuren at the Stedelijk Museum Amsterdam; the latter still counts as the introduction of conceptual art in The Netherlands.
