General request for a book on mathematical history, for a VERY advanced reader. I am aware that there are answered similar questions on here, however I am specifically after a text that would be engaging for a professor of mathematics, also Fellow of the Royal Society (FRS).
He is unwell and in the hospital, and I would like to get him something to pass the time. However anything aimed at undergraduate / postgraduate level is going to be far too patronising. Honestly, I'm not sure if there exists such a book, but if anyone has any recommendations, I would be extremely grateful. 

Another really good read is Constance Ried's book Hilbert, which (as the title suggests) covers the history of one mathematician in depth, but also touches upon many other mathematically "significant figures" as it tells its tale.
