In the first case, you don't have a big thing, but I will try to look into it more, ok? But in second case
we know that Wittgenstein in his "second phase" knew about James and he asked about how there
could be "pragmatist solution".
Now, about Heidegger and American Philosophers, you will find things with Rorty and
neopragmatism. Pay attention: Rorty is more like Sartre than we can be thinking about. Now,
Heidegger didn't like American Pragmatism, of course. But, Rorty has Heidegger like a partner
because Heidegger puts good questions about language, the end of Humanism and postmodernism
— and these are things that Rorty needs to talk about. Why? Because Rorty can put a conversation
with the World, putting the American Philosophy and the game again. Rorty crossing Atlantic Wall
and now Italy (and others) want know Davidson, Putnam and others because of Rorty.
