The Double Helix is one of the most significant first-hand accounts of the scientific process written during the 20th century. With 'Pepys-like frankness', Watson describes science as it actually happens, including the frustrations, dead-ends, and gritty politics. Richard Feynman praised this account, writing that 'he has described admirably how it feels to have that frightening and beautiful experience of making a great scientific discovery'. The Double Helix is also known for Watson's unashamed belittling of chemist Rosalind Franklin, whose work in crystallography formed the basis for Watson and Crick's analysis of DNA's structure.
