Gallerists like the German Karsten Greve are an important link between artist and audience. By exhibiting a high diversity of artistic genres, Greve keeps his collectors at pace with the times. Karsten Greve has been active in arts since 1969. He opened his own gallery in 1973 in Cologne, Germany with a solo exhibition of works by Yves Klein, one of the founding members of the French Nouveau Réalisme. Ongoing and intimate contact with artists like Cy Twombly or Louise Bourgeois finally set the scope of Greve’s artistic interests that he describes as follows: “Basically, the programme of my galleries is highly diverse. The artistic post-war genres I am interested in range from painting, drawing and graphic arts to sculpture, installation, and photography.”
