Alan Dower Blumlein (29 June 1903 – 7 June 1942) was an English electronics engineer, notable for his many inventions in telecommunications, sound recording, stereophonic sound, television and radar.〔 He received 128 patents and was considered as one of the most significant engineers and inventors of his time.〔 He died during World War II on 7 June 1942, aged 38, during the secret trial of an H2S airborne radar system then under development, when all on board the Halifax bomber he was flying in were killed when it crashed at Welsh Bicknor in Herefordshire.〔 ==Early life== Alan Dower Blumlein was born on 29 June 1903 in Hampstead, London to Semmy Blumlein, a German-born naturalised British subject. Semmy was born to Joseph Blumlein, a German of Jewish descent, and Phillippine Hellmann, a French woman of German descent.〔Semmy Blumlein's father, Joseph B. Blumlein was Jewish, ''see Burns, p. 2''〕 Alan's mother, Jessie Dower, was Scottish, daughter of a missionary. He was christened as a Presbyterian, though he later married in a Church of England parish. His future career seems to have been determined by the age of seven, when he presented his father with an invoice for repairing the doorbell, signed "Alan Blumlein, Electrical Engineer" (with "paid" scrawled in pencil). His sister claimed that he could not read proficiently until he was 12. He replied "no, but I knew a lot of quadratic equations!" After leaving Highgate School in 1921, he studied at City and Guilds College (part of Imperial College). He won a Governors' scholarship and joined the second year of the course. He graduated with a First-Class Honours BSc two years later. In mid-1930, Blumlein met Doreen Lane, a preparatory school teacher five years his junior. After two-and-a-half years of courtship the two were married in 1933. Lane was warned by acquaintances before the wedding that, "There was a joke amongst some of his friends, they used to call it 'Blumlein-itis' or 'First Class Mind'. It seems that he didn't want to know anyone who didn't have a first class mind." Recording engineer, J.B. Kaye, who was Blumlein's closest friend and best man at the wedding,〔Burns (2000), p.49〕 thought the couple were well matched.〔Alexander (1999) chapter 3〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alan Blumlein」の詳細全文を読む スポンサード リンク
