In 1987, the city of Udine held an International Congress in memory of Luigi Pio Tessitori on the first centennial after his birth. The Proceedings of the Congress, subsequently published (Luigi Pio Tessitori, Brescia, Paideia, 1990), focused on the wide array of topics which held the interests of this scholar from Friuli, and on the continuing relevance of his research on various aspects of literary and religious tradition, especially in the field of the history of mediaeval and modern Indo-Aryan languages.
The Congress proved to be a point of departure. The Società Indologica "Luigi Pio Tessitori" was established in Udine in 1993 with the aim of furthering studies of Tessitori’s work and bringing his unpublished writings – hitherto entrusted to his nephew, Dr. Peano, and deemed worthy of attention by acknowledged specialists – to press.
