Worth mentioning for those who grew up in the last fifty years - his first job title was "computer". He was one of those doing the stress calculations on R100 (Vickers' airship) - on paper, with (seven figure) log tables.
He was the founder and principal designer of the Airspeed aircraft company, builder of Britain's most advanced civil aircraft in the 1930s. And wrote under a pen name because he (probably correctly) thought that the board would think writing was an unsuitable occupation for their engineers!
