Some interesting notes on his time as President of Canisius University:
Father Van Rossum was a proponent of the movement for 'closed' retreats for laymen. Thomas Holling (printer and former Mayor of Buffalo) was one of the most active members of this retreat movement.
Father Van Rossum organized groups of laymen in Buffalo for retreats at Saint Stanislaus Novitiate in Cleveland. It was these men who erected a statue to Saint Michael the Archangel in his memory at the entrance to the Novitiate.
