David William Dye
David William Dye (born December 30, 1887 in Portsmouth , † February 18, 1932 ibid) was a British physicist and electrical engineer , known for precision measurement methods.
Life
He was the third son of Charles Dye, who was Mayor of Portsmouth in 1906. Dye went to a technical school in Portsmouth and studied at the University of London. He was then an apprentice at the British Thompson-Houston Company in Rugby and from 1910 at the National Physical Laboratory in Teddington, where he became head of the department for standards and metrology in the field of electricity and magnetism in 1919 (as successor to A. Campbell).
He developed precise measuring methods for capacitance and inductance also in the radio frequency range and for frequencies or wavelengths in the radio frequency range with a tuning fork control. This led to the development of a watch with an accuracy of 1 ppm compared to standard watches with a relative accuracy in the per mil range that were customary up to that time. He later developed quartz watches, which were further developed by Louis Essen in his laboratory. From 1927 he developed accurate magnetometers. It was able to measure the vertical component of the earth's magnetic field precisely and was installed in the Abinger Magnetic Observatory.
In 1928 he became a Fellow of the Royal Society . He was chairman of the UK Radio Standards Commission.
