There is no evidence that Fr. Georges Lemaître ever met Fr. Teilhard de Chardin, although their scientific careers overlapped to a considerable degree.
Both men were standouts in their fields-- Lemaître more so than Teilhard, I would say, but both attracted the attention of the press because of the fact they were Catholic priests as well as scientists, rare birds then, as now.
But only one of the two, Fr. Lemaître, was honored by his own Church, while Fr. Teilhard… was treated like a leper.
