The Hollandsche Patent Metaal Industrie or “HOPMI” was a manufacturer of several metal specialties. Parts for Bicycles for instance as locks. It also manufactured 2 HOPMI chairs designed by Gerrit Rietveld somewhere in 1932. One of the two was acquired by a Dutch Univereity professor, Prof. Lanjouw from Utrecht, whose heirs have given this chair on loan to the Central Museum of Utrecht in 2008. The Utrecht Central has the largest collection of Rietveld chairs. Then this chair was actually rediscovered. I posted about the discovery in 2008 already.
Later a Dutch architect, Victor Veldhuizen van Zanten gor the idea to create a limited edition of 250 Hopmi Chairs in cooperation with a grandson of Gerrit Rietveld, Egbert Rietveld, who runs the label Rietveld Originals.
The photo here I took at the home of a friend who has bought one of te limited edition chairs.
