Dr. Hans Koechler meeting with His Holiness Pope John Paul II on 26 February 1979 at the Vatican's Apostolic Palace.

Sul problema d'un'antropologia a base fenomenologica" at the Annual Conference of the Italian Section of the International Phenomenological Research Society in Viterbo near Rome (24 February 1979).
