[Math] Books you would like to see translated into English

Question

I have recently been told of a proposal to produce an English translation
of Landau's Handbuch der Lehre von der Verteilung der Primzahlen, and
this prompts me to ask a more general question:

Which foreign-language
books would you most like to see translated into English?

These could be classics of historical interest, books you would like your
students to read, books you would like to teach from, or books of use in
your own research.

Answer 1

Grothendieck's EGA and SGA.
