Here is Pais on Whittaker’s book on the history of relativity:
His treatment of the special theory of relativity in the latter volume shows how well the author’s lack of physical insight matches his ignorance of the literature.
Pais has good things to say about the first volume of the book though:
This work covers the period from Descartes to the close of the nineteenth century. Colleagues more knowledgeable on this period than I, confirm my impression that it is a masterpiece.
