Gallerist in Berlin.

From 1966 to 1972, Heidrich ran »galerie daedalus« in Berlin, concentrating in his shows on concrete, constructive, and kinetic art. In some of those shows he included computer art (by Frieder Nake), which by the time was rarely done by a private gallerist in a general context of art. On 1 September 2004, he started his second period as a private gallerist: »Heidrichs Kunsthandlung«, again in Berlin. He there put together a total of 32 exhibitions before exactly five years later (in 2009) he withdrew for good from this business. He is still offering for sale works of his art collection, whereas his small collection of computer art went to [DAM] Berlin.

There were in the mid and later 1960s only a few gallerists daring enough to exhibit computer art side by side with main stream (even if experimental) works of art. Galerie Swart in Amsterdam, Galerie im Hause Behr in Stuttgart, Galerie Obere Zäune in Zurich were some of those. These gallerists should be considered as the pioneers that, besides the artists themselves, were needed to accept computer art as a genuine development of fine art (and not just as a, perhaps, exotic flower).
