I do agree that a history of mathematics course should contain some mathematics content. Indeed, we have a requirement in our math department that a certain percentage of the course must involve such an emphasis. But one can do this is a relevant way by using, for example, the text by Howard Eves. There are many problems--some very challenging--which give a much better appreciation of the role of various individuals in the development of mathematics.
