Who first called the Grothendieck's schéma scheme? Grothendieck called "schemes" schémas in French.
I find it strange we call them schemes.
In fact, Grothendieck called them (pre-) schemas(this is an English word) in his talk(in English) at Proceeding of the international congress of mathematicians at Edinburgh in 1958.
There is an English word schema which means almost the same as French schéma.
I think English words schema and scheme have different meanings and nuances although they are similar.
So who first called Grothendieck's schéma scheme in English?
And why he did not call it schema?

Let’s see whether I can get my memory working right on this. It tells me that I was in the seminar that G gave at Harvard in 1958-59(*), I was a second-year grad student then. He talked about schemes, of course, and he did so in English. He certainly must not have called them “schémas” (pronounced shayma in French), because none of us called them that in discussions. So I hope I’m right in saying that G himself called them “schemes” from the get-go. And he would have made this decision, I’m fairly confident, on the advice of Tate.
(*)Maybe it could have been 1959-60; but those are the only two possibilities.
