This year represents the 60th anniversary of the publication of the famous paper by James Watson and Francis Crick proposing a structure for DNA. This podcast from Nature contains interviews with scientists who were actively involved in the race to work out the structure. Listen to the podcast. At approximately 7 minutes into the podcast, there is a remarkable description of Watson’s first look at the classic x-ray crystallography picture of DNA. Watson knew immediately what the picture represented because Crick had, two years previously, published a theoretical paper about what a helical diffraction pattern
would look like.
