One of my former students was asking about Emerson and Nietzsche. Quine even. Here was my first reply:
Nietzsche was vocal about his admiration of Emerson,
especially in his The Gay Science. One of Emerson's essays mentions the
over-soul.
A lot of Emerson's impact has been dampened by those who
think "American philosophy" is insignificant. Nietzsche was didn't
bother with such a view. In at least one instance Nietzsche wished he thought
in French or English, Walter Kaufmann, if I remember correctly also claimed Nietzsche
was aware of American English
