In the summer of 1969, the first European solo exhibition of American sculptor Kenneth Snelson takes place in the sculpture garden: six huge, dynamic constructions made of metal tubes and cables. There is ‘great interest in this technically and artistically unusual exhibition’.
Snelson’s assistant, the German artist Klaus Rinke, comes to Otterlo at the request of Ellen Joosten to instruct the museum’s staff in the complicated installation of the sculptures. Ellen Joosten also helps with the installation of Snelson’s sculptures.
After the exhibition, Oxenaar acquires the 30-metre-high Needle Tower II. He wants to exhibit the work permanently in the sculpture garden. ‘In the artist’s own opinion, the tower is the most persuasive realization of the construction principles that he develops in his work.’
