Born at Marsh Hall Farm in 1893, Chadwick was the family's fifth generation of engineers. He studied night school at the Manchester Municipal College of Technology (1907-11) while also training as a draughtsman at the British Westinghouse Electrical Company, which he joined as a 14-year-old.
As far as aviation was concerned, he was really in at the beginning, enthused by the new technology from the point when the Wright brothers took to the air in December 1903, Chadwick by then just a wide-eyed lad of 10.
At 18 yrs old, he began his association with Avro, he then worked on various designs in the lead-up to WW1 including the Avro 504, a Great War light bomber and trainer. King George VI learned to fly on one of these when he was Duke of York, while the very first QANTAS was an Avro 504K.
When still only 22, Chadwick designed the Avro Pike twin-engine bomber (1915), the first bomber to have internal bomb stowage and a gun turret, and his rapid ascent continued, for in 1918 Chadwick had become Avro’s chief designer, coming up with the first true light aeroplane, the aptly-named Avro Baby.
Two years later he added the world’s largest single-engine bomber.
A variant of the Baby, the Antarctic Baby, was supplied for explorer Sir Ernest Shackleton’s final expedition to the Antarctic (1921).
