In the mid-1950s, the Philips Netherlands company was renowned for the outstanding quality of all mechanical assemblies and parts in their test & measurement and communications equipment. This must have been due largely to the scientific foundations laid by the renowned Philips' Physics Labs (Natuurkundig Laboratorium) where some of the most brilliant physicists and mechanical engineers were given total freedom to perfect their art—with no lack of funding either.
