The Centraal Museum has launched the Rietveld collection online. Visitors of the website will find more than 8000 objects by Gerrit Rietveld (1888-1964) kept by the Centraal Museum. The objects in question consist of mostly 8000 archive items and almost 300 museum objects, most of which furniture. Many people are familiar with the red-blue chair and the Rietveld Schröder House, but Rietveld designed many more pieces of furniture and houses. The website collectie.rietveldjaar.nl provides a complete overview of Rietveld’s entire oeuvre. It is quite unique that such a large part of a designer’s work has been retrieved.
