I want to know the answer to the following question:
Who did Waldemar Gurian receive his tutelage under while seeking his doctorate?
All the background I'm provided with is that "Yves Simon (1903–61), brought to ND in the 1940s the insights of French studies in the Aristotelian-Thomistic tradition of philosophy; his own teacher Jacques Maritain (1882–73) was a frequent visitor to campus.". Is that enough to answer the question?
Answer: no
