Is there a book or a site or a periodic or a encyclopedia or something like this that's a
complete reference in math history, talking about all known mathematicians and their achievements, not saving pages?
For example, a encyclopedia who talks about
Euler and his achievements, not saving pages to talk about him?
I have the Carl Benjamin Boyer book and had seen some websites, but didn't find what I'm looking for yet. If anyone knows a good place to get knowledgment about math history, mathematicians and their achievements please I would like to know.
