According to CUA officials, “Because of the splendid impression which Dr. Riccobono’s conduction of this series effected upon his audience, there was a spontaneous movement to insure the continuation of this or similar lectures in future years.
"[6] Following this inaugural session, the Seminar appears not to have met again until October of 1930, even though the group's intention was to meet monthly during the academic year.
In the next several years, the Riccobono Seminar reconvened sporadically at various District of Columbia law schools approximately twenty times.
"[9] Once on a sound financial and institutional footing, the Riccobono Seminar provided a forum in which leading American scholars of Roman law presented and discussed the results of their research.
[10] The list of Riccobono Seminar presenters includes many of the best regarded Roman law scholars and legal historians of the time.
Among these were : H. Milton Colvin, Roscoe Dorsey, Charles S. Lobingier and Fritz Schulz (jurist);[11] A. Arthur Schiller, Francis de Zulueta, J.B. Thayer, Ernest Levy, and Judge Fred H.
From the 1935-1936 sessions through those of 1938-1939, when the Second World War began, Riccobono offered extensive summaries of the Seminar’s papers and discussions in a special section of the “Bullettino” titled “Il Diritto Romano in America.” These reports ceased in 1940.
[18] However, in its prime during the decades of the 1930s and 1940s, the Riccobono Seminar admirably fulfilled its constitutional object of disseminating the knowledge of Roman law.
