I just picked this image up off ChopperDave's blog...
Stanley Hooker was an engineer who began work for Rolls Royce towards the end of WWII. He was involved in the latter development of the Rolls Royce Merlin 27 Litre V12 that powered many of the iconic aircraft of that era - Spitfire, Hurricane, Mustang, Mosquito to name but a few.
He was initially involved in supercharging the Merlin taking it from approximately 1,000 HP to an eventual 2,000 HP (from the same 27 litres). From superchargers, it's not a huge leap to radial jet engines and he was involved in improving the efficiency of the Whittle engine. And from radials it's just a hop, skip and a jump to axial jets.
Hooker was central to the development of the then nascent jet engine, eventually transitioning from military aircraft to jet liners.
He was a very likable and humble man with a good turn of phrase, who lived in interesting times. This makes for a good autobiography and I'd recommend it to anyone with an interest in engines or just anyone who likes a good story.
