Biography

Anthony Fokker was one of the most important Dutch Professors and Doctors in theoretical physics of his time. He started studying in 1906 at the State University in Leiden, where he promoted under Noble price winner Lorentz. He worked in 1914 with Rutherford and Bragg in England and in the winter of 1913-1914 with Einstein which led to a joint publication of Einstein and Fokker.^[1]He derived the Fokker–Planck equation along with Max Planck.

Fokker designed and had built a number of keyboard instruments capable of playing microtonal scales via a generalized keyboard. The best-known of these is his 31-tone equal-tempered organ, which was installed in Teyler's Museum in Haarlem in 1951. It is commonly called the Fokker organ.
