David Theodore Nelson Williamson (also known as D.T.N. Williamson; 15 February 1923 – 10 May 1992) was a British electronics engineer, elected a Fellow of the Royal Society (F.R.S.) in 1968, most notable for a design of early high fidelity valve amplifier known as the Williamson amplifier[1] that originally featured "OSRAM" brand valves (such as KT66 "Kinkless" Tetrode and L63 triode) made by the M. O. Valve Company, for which he had worked until 1946. The design was published in a series of articles in the influential British "Wireless World" magazine, beginning in May 1947.

He continued his interest in hi-fi and writing for "Wireless World" after his move to Ferranti, and became Group Director of Engineering with Rank Xerox Ltd 1974 before retiring in 1976.
