A very rare pair of 1950s walnut lamps with Rotaflex shades. Rotaflex was a type of plastic and the method for its production developed in France in the 1950s and utilized for lighting by various designers. The term also refers to the patented method for producing such plastic. This pair was designed and produced by Yasha Heifetz of Heifetz Manufacturing USA and feature beehive-shaped shades with solid walnut bases. They are in near-mint condition and have been professionally rewired.

ROTAFLEX™ is the name of a patented method of spinning cellulose acetate 'yarn' into a lampshade. The patent filed in 1946 by Danish civil engineers Bent Højberg Pedersen and Bent Panker describes the process by which a thermoplastic, bioplastic cord of cellulose acetate is spun onto a mold by hand. Cellulose acetate is an early acrylic with various trade names: Rhodoid in France and the UK, Tenite in the US, and Cellon in Germany. It's lighter than glass, less fragile than paper, and it allows a great variety of shapes in many colors at a reasonable price. Moreover, it gives a beautiful light. The objects produced by the Rotaflex process retain the shape of the underlying mold. Several elements can be glued together to create complex-shaped parts.

Navigating the world of Rotaflex lamps can be confusing as the term 'Rotaflex' can designate the materials method patented by Bent H. Pedersen, diffusers thus produced, as well as the British brand founded in 1953 by Bernard Stern (Rotaflex LTD) and several other companies and brands that developed in quick succession, all interconnected via licensing. The first lamps branded Rotaflex were manufactured circa 1952 in France by Charron and Disderot from early designs by André Simard and René-Jean Caillette. In 1954, the company L'Atelier de Recherche Plastique (Plastic Research Workshop), aka ARP, was founded by Pierre Guariche (1926 – 1995), Joseph-André Motte (1925 – 2013), and Michel Mortier (1925 – 2015). The three met while working in the design agency of Marcel Gascoin. They aspired to shake up the codes of classicism by drawing on new forms to create more accessible furniture and lighting designs. They seized upon the Rotaflex method to accomplish several outstanding lighting designs under the ARP label. They participated in the Salon des Arts Ménagers (Household Arts Fair) in 1954 and received numerous prizes. Their furniture and lamps were produced by companies such as Airborne, Disderot (Atelier Pierre Disderot), Meubles TV, Huchers-Minvielle, Luminalite, Steiner, and Rotaflex. ARP was dissolved three years later in 1957.

In 1953, the British company Rotaflex was founded by Bernard Stern, a painter turned industrialist, who commissioned John and Sylvia Reid to design lamps that received several awards.  When he registered the Rotaflex brand in 1953, Stern rented a former agricultural building in order to produce a range of lights using the process developed by Bent Hojberg Pedersen. The lampshades thus produced were very light and easy to package for transport.  In just a few years, Rotaflex became one of Britain’s leading lighting makers, in no small part thanks to the design work of John & Sylvia Reid who were two of the most well-known consultant designers for Rotaflex. In addition to their many spun cellulose acetate lamps, they enhanced the range with the ‘Christals’ series, made of cellulose acetate sprinkled with countless tiny lucite bits to resemble sugar balls in various colors.  The couple is also famous for their Metallux, Interplay, Honeycombs, Fernland Cylinders, and Sphere lamp designs, as well as many more.  Rotaflex received several design awards including the iF Design award for their cellulose acetate pendant lamps in 1957.  British Rotaflex lamps were distributed in France by Disderot and vice versa. Sadly, the Rotaflex company no longer exists. 

As of 1955, the US company Heifetz led by Yasha Heifetz (not to be confused with the famous violinist Jascha Heifetz), sold Rotaflex lamps of his own designs as well as others but also served as the American distributor of the British Rotaflex lamps, all of them labeled Heifetz Rotaflex or Heifetz.  Lightolier and Verplex also produced and sold their own designs.

In addition, the name Rotaflex was utilized by other companies, either using the manufacturing process or distributing the British Rotaflex lamps in their respective countries such as Plastex and Stockman Orno in Finland.  In the USA they were produced and sold by Heifetz, Lightolier, and Verplex, and by Kempthorne in Australia where the material was named Spunlite.  In Germany, Sompex Licht und Form, and Rolf O. Burghard KG Düsseldorf, produced and sold them. In Belgium and some other European countries, they were sold by Massive. Disderot produced and sold them in France, and Philips from The Netherlands had some lamps in their collection.  In Sweden, they were designed by Alf Svensson, Bertil Roos, and Sigvard Bernadotte, and produced by Bergboms under the name Rotoflex (slightly different spelling).

Despite its international influence and longevity, documents about Rotaflex are quite rare, and many inaccuracies (including, no doubt, in this text...) remain.  Two catalogs and some advertisements attest to the French manufacture of some forty models and Finnish, American (Heifetz) and British documents testify to a much larger production.
