Philips Natuurkundig Laboratorium


The Philips Natuurkundig Laboratorium or NatLab was the Dutch section of the Philips research department, which did research for the product divisions of that company. Originally located in the Strijp district of Eindhoven, the facility moved to Waalre in the early 1960s. A 1972 municipal rezoning brought the facility back into Eindhoven, which was followed some years later by Eindhoven renaming the street the facility is on into the Prof. Holstlaan, after the first director.
In 1975, the NatLab employed some 2000 people, including 600 researchers with university degrees. Research done at the NatLab has ranged from product-specific to fundamental research into electronics, physics and chemistry, as well as computing science and information technology.
The original NatLab facility was disbanded in 2001 and the facility has been transformed into the High Tech Campus Eindhoven, which is open to researchers from many different companies. Philips Research is still one of the largest campus tenants, although not with anything like the number of people employed in the NatLab days. Philips Research also has branches in Germany, the United Kingdom, United States, India and China; the non-Netherlands parts of Philips Research account for about half the research work done by Philips nowadays.

History

The history of the NatLab spans roughly three periods: 1914–1946, 1946–1972 and 1972–2001.

The start: 1914-1946

The NatLab was founded in 1914 after a direct decision of Gerard and Anton Philips. At the time Philips was branching out into different areas of electronics and they felt the need to do in-house research to support product development, as well as create a company patent portfolio and reduce the company dependence on patents held by third parties. They hired physicist Gilles Holst who assembled a staff consisting of Ekko Oosterhuis and a small number of research assistants; this was the entire scientific staff of the facility for the first decade. Holst held the director's position until 1946 and spent his tenure creating and maintaining an academic atmosphere at the facility in which researchers were given a lot of leeway and access to external research and resources. The external access also included :wikt:colloquium|colloquia by some of the great physicists of the day.
This managerial philosophy made the NatLab very different from all the other Philips facilities and laboratories. Unlike the other Philips labs, NatLab was more like the AT&T Bell Laboratories in the United States. The research was also not limited to industrial research; a good deal of fundamental research was also performed at NatLab, such as that of Bernard D. H. Tellegen and Balthasar van der Pol. Van der Pol was hired in 1922 to start a research program into radio technology. This research program resulted in publishable results in the areas of propagation of radio waves, electrical circuit theory, harmonics and a number of related, mathematical problems. Van der Pol also studied the effect of the curvature of the Earth on radio wave propagation.
Van der Pol's senior assistant was Bernard Tellegen. He started working on triodes and invented the penthode in 1926. The penthode was the centerpiece of the famous Philips radio and it soon found its way into every radio and amplifier in the market. Tellegen also did pioneering research in the area of electrical networks. In 1925 Van der Pol took on a junior student from Delft, Johan Numans. Numans designed and built a short wave crystal controlled telephony transmitter for his required period of practical work, with call sign PCJJ. This transmitter made world headlines on March 11, 1927 when it transmitted practically undistorted music and voice across the entire globe. As a result of this, the Philips Omroep Holland-Indië was founded.

Growth and success: 1946-1972

In 1946 Holst was succeeded by a triumvirate: physicist Hendrik Casimir, chemist Evert Verwey and engineer Herre Rinia. The NatLab saw its heyday under this triumvirate.
For the Philips company as a whole, the era of Frits Philips had made the company part of the world's electronics giants with 350.000 employees in 1970. NatLab grew right along with the company and became a world class research facility. By 1963 a new campus was designed for the facility in Waalre, with space for 3.000 employees. NatLab never grew to quite those numbers though, 2.400 was the record - and that included the foreign branches which had been added in the meantime. The NatLab became a superuniversity where the "best of the best" could do research in practically perfect circumstances. Kees Schouhamer Immink, digital pioneer and one of NatLab's top-scientists, formulated the atmosphere at that time: "We were able to conduct whatever research we found relevant, and had no pre-determined tasks; instead, we received full freedom and support of autonomous research. We went to work, not knowing what we would do that day. This view -or rather ambiguous view- on how research should be conducted, led to amazing inventions as a result. It was an innovation heaven". In 1968 Kees Teer became director.
The result was a slew of commercial and fundamental results, including the cassette tape in 1962, Plumbicon camera tube and the Video Long Play disc, which was the technological basis for the 1980 compact disc. Results were also achieved in the area of integrated circuitry: Else Kooi invented the LOCOS technology and Kees Hart and Arie Slob developed the I²L in the early 1970s.
Dick Raaijmakers and Tom Dissevelt did fundamental user experience research into the first synthesizers, resulting in internationally acclaimed electronic music and jazz music.

The end: 1972-present

The period under Casimir was a time of great success and achievement for the NatLab. But the time after his retirement in 1972 was one of decline and loss.
In 1973, starting with the oil crisis, the long period of economic growth came to an end and companies could no longer afford expensive research departments. With that economic reality, the belief in the stimulating value of fundamental research also seemed to disappear. On top of that, a number of bad decisions by the NatLab management did little to ingratiate the facility to the Philips Board of Directors, which has reduced the on-site size of Philips Research to 200 as of 2016.
