Did Grothendieck and Hörmander ever meet?
I have no definite answer to your question. However, it seems that Hörmander does not quote Grothendieck in any of his books. Hörmander's main reference in Functional Analysis was Laurent Schwartz' treatise on Distribution Theory as well as Gelfand & Shilov' Generalized Functions.
