Alan Dower Blumlein was a genius and has been described as the greatest British electronics engineer of the twentieth century. Although he was tragically killed at the age of 38, he contributed enormously to the fields of telephony and electrical measurements, monophonic and stereophonic recording and reproduction, high definition television, electronics, antennas and cables, and radar systems of various types. His accidental death in June 1942 was described by an Air Chief Marshal as 'a catastrophe', and the Secretary of State for Air said that 'it would be impossible to over-rate the importance of the work on which [Blumlein was] engaged': his loss was a 'national disaster'. He was responsible for saving many thousands of lives during the Second World War, and his endeavours in peacetime led to pleasure being given to millions of people.
This meticulous, extensively researched and well-referenced book presents a balanced account of the life and times of a brilliant engineer. It is certain to be the major biographical source on Blumlein for all historians of technology and science.
From the first notions of 'seeing by electricity' in 1878, through the period of the first demonstration of rudimentary television in 1926 and up to 1940, when war brought the advance of the technology to a temporary halt, the development of television gathered about it a tremendous history. Following the discovery of the photo-conductive effect, numerous schemes for television were suggested but it was in the wake of Baird's early demonstrations that real industrial interest developed and the pace of progress increased. Much research and development work was undertaken in the UK, the US, Germany and France. By 1936 television technology had advanced to the point where high definition broadcasting was realistic.
This meticulous and deeply researched book presents a balanced and thorough international history of television from 1878 to 1940, considering the factors - technical, commercial and social - that influenced and led to the establishment of public services in many countries. Highly illustrated throughout, this is a major book in the study of history of science, technology and media.
On 2 November 1936 the world's first high definition television station was inaugurated at Alexandra Palace. Two competing companies, Marconi-EMI Television Company Ltd and Baird Television Ltd, provided studio and transmitting equipment for the new service which operated, on an alternate basis, with the systems of the two companies. After a trial period the 405-line system of the Marconi-EMI company was adopted and the last transmission by the 240-line system of Baird Television Ltd was sent out on 30 January 1937.
This book is concerned with the history of British television for home reception from 1922/23 to 1939, when the London Station closed down for the war years. Great care has been taken to ensure that an unbiased, accurate history has been written and the work is based predominantly on written primary source material. More than 900 references are given in the text, which is illustrated with many photographs and illustrations.
An endeavour has been made to present a balanced history rather than a purely technical history. Thus the book considers the factors - technical, financial and general - which led to the establishment of the world's first, all-electronic, public, regular, high definition television broadcasting service.
