author
b. 1876
A scholar of Romance languages, he is best remembered for a landmark early study of the Catalan chivalric classic Tirant lo Blanch. His surviving published record points to a careful academic voice with a strong interest in medieval literature.

by Joseph Anthony Vaeth
Joseph Anthony Vaeth, born in 1876, is identified in the published record as the author of Tirant lo Blanch; A Study of Its Authorship, Principal Sources and Historical Setting. The 1918 Columbia University Press edition describes him as "Joseph A. Vaeth, Ph.D." and notes that he was an instructor in Romance languages at New York University.
That book grew out of doctoral research at Columbia University and focuses on the famous Catalan romance Tirant lo Blanch, a work long connected with the history of Spanish and medieval literature. Based on the sources I could confirm here, Vaeth appears to have been an academic specialist rather than a widely documented public literary figure.
Reliable biographical details beyond his birth year are scarce in the material I was able to verify during this search, so a fuller life sketch would need stronger archival or library sources.
