I'm not a Heideggerian scholar, but I recall from several places he thought ill of Sartre. ---------- Well, I am a Heidegger scholar (or was going to be, before I dropped out of my doctoral program halfway through the dissertation). :)
Heidegger was friendly to Sartre on the two occasions he invited him up to his hut, but Heidegger was famous for unctuous ass kissing.
