Inspired by the folding chair of Joseph Beverly FENBY (see below), the BFK chair has been created by in 1938 by a group of Argentine architects and designers (ancient collaborators of LE CORBUSIER in his architecture company in 1937) for their own offices. This metal version manufactured by ARTEK-PASCOE, won the argentine award for design in 1940. After the war, this chair has been one the first successful model of the KNOLL company. Just after, KNOLL lost a trial concerning the reproduction rights, so manufacturers copied this model without license.
