History:
N.V. Nederlandsche Instrumentenfabriek Waldorp was established on August 7, 1915 in Den Haag. Most probably the name was derived from the fact that the company was situated at the Waldorpstraat in Den Haag. Initially Instrumentenfabriek Waldorp was only involved in the production of instruments, but in 1923 its first radios were produced. In the years thereafter not very much activity with regard to radio business was seen, but that situation changed after a new daughter company "N.V. Waldorp Radio" was founded on December 5, 1930. As from 1931 Waldorp Radio designed and sold various models with the brandname Waldorp and it became one of the major radio manufacturers in The Netherlands, though small compared to the giant Philips.
As from 1937 Waldorp radios were no longer own designs, but based on Philips chassis and Waldorp cabinets. After the Second World War Waldorp Radio continued to produce radios with the brandname Waldorp, but at the end of the decade it also used the name Waldorp-Fridor and Fridor-Waldorp and also entered into the business of other products, like irons and vacuum cleaners. In 1950 the brandname Fridor was officially added to the list of brandnames and in the year thereafter the name of the company was changed into "N.V. Fridor Fabrieken". It is very likely that these moves were the result of changes in the ownership of the company. Radios produced as from the year 1951 only carried the brandname Fridor.
Unfortunately the business did not develop as desired and N.V. Fridor Fabrieken went bankrupt in the beginning of 1954. The last models originate from the year 1951/1952.
