I posted before about a Radio 4 programme by Melvyn Bragg about the Braggs last November. Since then I've met Professor Mike Glazer, who put him up to it. Professor Glazer has done a lot to remind the world of the contributions of William Henry Bragg and Laurence Bragg to X-ray crystallography. It is coming up to the centenary of the discovery and their joint Nobel Prize. Melvyn Bragg, an old boy of the school, has done another programme about them, having found out that he is indeed a distant relative. William Bragg was born 5 miles from here! Here's the link to the programme.
