Noted philosopher and theologian Santiago Maria Ramirez y Ruiz de Dulanto (1891-1967) completed his licentiate and doctorate in philosophy at the "Angelicum" from 1913 to 1917 with a dissertation entitled "De quidditate Incarnationis", becoming lector on 27 June 1917 and teaching there from 1917 to 1920. Ramirez relates that he was fortunate during his student years to hear Pope Pius X deliver a talk to the professors and students at the "Angelicum" on 28 June 1914 in which the Pontiff extolled Aquinas' doctrines above those of all others, and another talk delivered by Pope Pius XI at the "Angelicum" on 12 December 1924 in which he reaffirmed the doctrinal authority of St. Thomas Aquinas.
