But it was not just stumbled upon - it was a race. Specifically, it was a race between two teams of young scientists working in Britain. Rosalind Franklin and Maurice Wilkins were trying to identify the structure by studying X-ray diffractions of the DNA molecule. But Jim Watson and Francis Crick studied a little bit of everything -- includin
