Roy Chadwick, CBE, FRSA, FRAeS (30 April 1893 – 23 August 1947) was an aircraft design engineer for the Avro Company. Born at Marsh Hall Farm, Farnworth, Widnes, the son of the mechanical engineer Charles Chadwick, he was the chief designer for Avro and was responsible for practically all of their aeroplane designs. He is famous in particular for designing the Avro Lancaster bomber, its follow-up Avro Lincoln and preliminary designs of the Avro Vulcan V-bomber. He also converted the Lincoln into the Shackleton. His Avro Yorks carried one-third of the entire British tonnage during the Berlin Airlift. Chadwick married Mary Gomersall in 1921 and had two daughters. Early life Chadwick attended St Clements Church School in Urmston, then studied at night school from 1907 to 1911 at the Manchester Municipal College of Technology whilst training as a draughtsman at the British Westinghouse Electrical Company in Trafford Park under George Edwin Bailey of Metropolitan-Vickers. Avro years At age 18 in September 1911, he began work as Alliott Verdon-Roe's (later Sir Alliott) personal assistant and the firm's draughtsman at A.V. Roe and Company, Avro, based at Brownsfield Mill, Manchester. Under the direction of A.V. Roe, Chadwick drafted the Avro D, a two-seater tractor biplane, the Avro E, which was converted to a floatplane, and in 1912, the Avro F, the world's first monoplane and enclosed-cabin machine. He then worked on the draughtsmanship for the Avro 500, 501 and 503, which led to Avro's World War I light bomber and trainer, the Avro 504. In 1915 at age 22, Chadwick designed the Avro Pike, a twin-engined pusher biplane bomber. That year, when starting to design entire aircraft, he was based at Hamble, near Southampton. In 1918 he was appointed Avro's Chief Designer when Avro had about 40 employees. He designed the Avro Baby and in 1920, the Avro Aldershot, the world's largest single-engined bomber and variants of the Aldershot, the Avro Ava and the Avro Andover. In 1925 he designed an all-metal plane, the single-seater fighter Avro Avenger and in 1926, the Avro Avian in which Bert Hinkler flew the first solo flight from England to Australia in 1928. In 1928, he moved back to the Avro factory in Woodford, Greater Manchester, used by BAE Systems until its closure in 2012. That year, he designed an eight-passenger high wing plane, the Avro 10 and a four-passenger version, the Avro 4. In 1929,
