Harry Ogden: the man with the chalk
Picture Newmarket in the 1790s. Organised thoroughbred racing is already almost a century old, and the betting is simple to the point of crude: you can back the favourite, or you can back "the field". Everything that isn't the favourite gets lumped together as one big, lazy alternative.
Then, so the story goes, a man called Harry Ogden turns up and does something nobody taking bets has done before. He chalks up a price about every runner on the card. Punters love it, because suddenly the second favourite and the 20-1 shot each have their own odds. The layers love it too, because it makes them money. Before long, everyone is copying him.
Tradition calls Ogden the first bookmaker, and the date usually given is 1795. Whether or not he was truly first, his idea has lasted better than almost anything else from Georgian England. Every price you see on a betting app today, on a Premier League match or a Tuesday night at Wolverhampton, is a direct descendant of that chalk board.
The history of bookmaking in Britain is the story of that one idea surviving two centuries of moral panics, police raids, tax wheezes and technological upheaval. Know the story and you'll never look at tonight's prices the same way again.
