RIP Tony Broad – creator of Nobel-prizewinning X-ray tube

I’ve just been told by the writer Henry Nicholls, who interviewed him in 2009, that the engineer Tony Broad died last week at the age of 93. It is one of my sins of omission as a writer that I did not interview Broad myself when I undertook my research for  Max Perutz and the Secret of Life, though I did acknowledge his critical role in the solution of the first protein structures.
