Last Friday we had the pleasure of hosting the Winter Lecture Series 2014 with Ronen Kadushin. Ronen Kadushin is a designer and also a design educator living in Berlin since 2005. He taught furniture design and design creativity courses at leading Israeli and European design academies since 1993. In 2004 Kadushin developed the Open Design concept, where the designs of his products can be downloaded, copied, modified and produced, much as in Open Source software. Based on this concept, he formed Open Design, a design and production company for furniture, lighting and accessories which are produced in Berlin and sold in Europe and the USA. Open Design products are regularly presented in solo and group exhibitions world wide, and published in professional literature. Kadushin is teaching Open design courses in universities and speaks at conferences. Kadushin is the author of the Open Design Manifesto.
