The Mastermind
Although it still isn’t certain who first had the idea to pull off the heist, Bruce Reynolds, a burglar and antique dealer in London, has become known as the mastermind. He had just ended his time in prison in 1962 and immediately began to assemble his crew.

Reynolds, who became one of the most notorious criminals in British history, started by taking in his own men called the”South West gang”, and he chose gang member Gordon “Goody,” who was a London hairdresser and part-time thief, to be his Number 2.
But it was Ronnie Biggs that ended up becoming the most famous from the gang.
