Marko Pogačnik was born 1944 in Kranj, Slovenia. He earned his degree in sculpture at the Academy od Fine Arts in Ljubljana 1967. He lives, with his family, in Šempas, Slovenia.
Pogačnik is one of the founders of OHO. Between 1965 and 1971 he worked as a member of the OHO group in the fields of conceptual art and land-art. His art practice during the OHO period included drawings, comics, performance, experimental film, concrete poetry and essays. From 1964 Pogačnik created "products" (imprints of everyday objects in plaster), followed by works based on strict numerical programs. In 1969 he developed installations based on the relationships of elements within the same "family" of items. His exhibitions include the Information Show at the Museum of Modern Art in New York 1970, Aktionsraum, in Munich in 1970, and the Global Conceptualism Show 1950-80, at the Queens Museum of Art in New York, 1999.
In 1971 he founded, together with his family and friends, a rural and artistic community, the "Family of Šempas" at Šempas, Slovenia, which existed until 1978. Exhibitions by the Family include Trigon 1977 in Graz and the Venice Biennalle of 1978.
Since 1979, Pogačnik has been engaged in geomantic and Earth healing work. In the mid 80-s he developed a method of Earth healing similar to acupuncture. He used stone pillars with carved cosmograms, and positioned them on acupuncture points on a chosen landscape, and named it "lithopuncture".
