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

Gilles Holst (the first director) 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 had intellectual freedom and access to external research and resources. The external access also included
colloquia by some of the great physicists of the day (including

Balthasar van der Pol. Van der Pol was hired in 1922 to start a research program into

Van der Pol's senior assistant (hired in 1923) was
Bernard Tellegen. He started working on triodes and invented (with his director Gilles Holst) 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

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 (PHOHI, the ''Philips Holland-Indonesia station'') was founded.
Growth and success: 1946-1972
In 1946 Holst was succeeded by a

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 (more than any Dutch university). 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 (full

, 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".

Kees Teer became director.
The result was a slew of commercial and fundamental results, including the

The end: 1972-2012
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 (such bad decisions including the development of the flopped

played an instrumental role in its design. For the industry group 'Audio' and the NatLab the development of a small optical audio disc started early in 1974. The sound quality of this disc had to be superior to that of the large and vulnerable vinyl record. To realize this, Lou Ottens, technical director of 'Audio', formed a seven-person project group. Vries and Diepeveen were members of this project group. In March 1974, during an Audio-VLP meeting Peek and Vries recommended a digital audio registration because an error-correcting code could be included. Vries and Diepeveen built an error-correcting coder-decoder that was delivered in the summer of 1978. The decoder was included in the CD prototype player that was presented to the international press. The error-correcting coder-decoder was abandoned in 1979 in favor of

To commemorate this breakthrough, Philips received an IEEE Milestone Award on March 6, 2009.
This breakthrough was also appreciated by Sony and they started a cooperation with Philips that resulted in June 1980 in a common CD system standard.

that the research management was a chaos which spoiled the atmosphere. As a result, academic freedom was far gone. Fundamental research, research driven purely by curiosity, was strictly reined in and priority was given to the short-term interests of the product divisions.
