I'd never realised what a phenomenon George Stephenson was. He became obsessed with engines as a child brought up in a large, poor family in a Northumbrian coal-mining village. He couldn't read till he was twenty. At a time when social mobility was something new, he ended up with international fame, vast wealth, retirement in a huge country estate, and his son Robert continuing the business. He not only developed the 'locomotive engine' (initially as a way to transport coal more efficiently in the Killinghall mine) but found time to develop rail-tracks, invent a mining safely lamp, improve mining lifts, mend clocks as a sideline, and indulge an interest in wildlife. He built bridges, tunnels and other civil engineering works that were unprecedented for their size and technical novelty, fought opposition from aristocrat landowners and canal companies over railway routes, struggled in parliament to get bills through and had fierce rivalries (but also friendships) with other developers, as his invention spread across the world with astonishing speed.
This biography is a heroic Victorian hagiography - there's little criticism of either father or son - with extensive praise of the railways as a 'benefit to mankind' built 'at no cost to the public purse'. It makes you want to become an engineer when you grow up.
