Career
He was known for his emphasis on stylistics. He was a doctoral student of Wilhelm Meyer-Lübke, receiving his doctorate in 1910. He was a professor of the University of Marburg in 1925, at the University of Cologne in 1930.
He left Germany in 1933, moving to Istanbul.
From there he went to Johns Hopkins University in 1936 (succeeding the chair in Romance philology left vacant with the death of David South Blondheim in 1934), where he remained for the rest of his life. According to René Wellek and Austin Warren:
Leo Spitzer early applied by investigating the recurrence of such motifs as blood and wounds in the writings of Henri Barbusse.
Later, Spitzer has tried to establish the connexion between recurrent stylistic traits and the psychology of the author, e.g. he connected the repetitive style of Péguy with his Bergsonism, and the style of Jules Romains with his Unanimism.
