QUESTION [9 upvotes]: Where can I find a proof of the de Rham-Weil theorem? 
Does anyone know?

REPLY [12 votes]: Andrew Fanoe,  a former student of mine,  wrote his senior thesis on various proofs of  the DeRham theorem.  In particular he discusses in detail Weil's very elegant proof of DeRham's theorem.  Andrew's presentation  uses a more  modern language, but all the ideas are in Weil's paper. In any case, here is the link to Andrew's thesis.     It's worth having a look at it. It is well written  and may have references you might find useful.
