ALAN DOWER BLUMLEIN (1903 - 1942)
Alan Dower Blumlein was known as the greatest circuit designer and originator. He is considered to be one of the best electronics engineers in Britain. To a few electronics enthusiasts Blumlein is a legend, to most and to the general public he is unknown.
Alan Dower Blumlein was born on 29 June, 1903 at Hampstead in London, the son of Semmy Joseph Blumlein, a French mining engineer, and Jessie Dower, the daughter of a Scottish missionary. His parents met in South Africa but had settled in London where Blumlein spent most of his childhood. A year after Alan‟s birth his father became a British subject.
At five Alan Blumlein entered school which, years later, he still liked to visit. It was on one of these visits that he met his future wife Doreen. They were married in 1933 and had two sons, Simon and David.
At primary school he was allowed considerable freedom in his choice of studies and it has been said that at the age of twelve he “could not read, but knew a lot about quadratics”.
In 1923 he graduated with a first - class honours degree in heavy electrical engineering from the City and Guids College, part of the Imperial College, London. He remained at the College as a demonstrator working with Professor Edward Mallett who was running a telephone engineering course. Together they devised a method of high-frequency resistance measurement. It was the publication of this work that led the IEE to demand that they “improve the English”. They must have done so, for the final version was awarded a premium. Blumlein was just 21 years old. In September 1924 Blumlein‟s industrial career began when he joined International Western Electric. He solved many complex problems. During his working life he accumulated 128 patents, roughly one every seven weeks. His achievements would be a fitting memorial if better known.

Вопросы:
