Holst and Bouwers realised that this same principle could be used to connect metals to glass. This was relevant to all sorts of tubes whereby a glass bulb had to be fitted onto a metal socket. Lab. 22 The Mullard Radio Valve Company in England expressed an interest in this process and negotiations between Philips and that company led to Philips taking a financial interest in the Mullard company. Many years later, after WWII, the Mullard lab became part of the Philips research organisation. As nationalistic feelings were quite strong at that time, Philips initially avoided associating its own brand name with the Mullard lab.

At the same time the company was able to make use of the opportunities provided by the new radio market, thus softening the blow of the economic crisis in its early years. Later on, it became evident that further diversification would be necessary if the continued economic problems were to be counterbalanced, and in 1937 the company again decided to extend its product scope. 10 The success of this strategy of diversification could be attributed to the fact that the consumer market kept growing in spite of the economic crisis.

Van der Pol had studied mathematics and physics and already had a good reputation. It is evident that Holst wanted him to join the staff because of his specific expertise in this area. Lab. by developing new types of receiver tubes. In particular, he endeavoured to improve on the low energy use of the tubes that RCA and Marconi produced. Initially, the work did not yield results any better than those produced by RCA and Marconi, but by concentrating much of the total research effort on this problem – according to one of Holst’s notebooks, 9 of the 16 scientists were working on this – the study into the effect of a layer of barium oxide on a tungsten wire had, by 1924, yielded a procedure for making what were known as oxide cathodes.
