Br Jesper spent over 11 years in Glin from the late 1940s. He held the position of Councillor for his first seven years, before taking over as Sub-Superior in the mid-1950s. The Visitation Reports reveal that he could be a difficult person to get along with and was acknowledged as being odd. The Visitor noted that relations between him and a number of Brothers were bad and, when questioned on the matter, his colleagues accused him of having a very bad temper. The Visitor subsequently remarked that Br Jesper was ‘not quite normal’. He was suspicious and aloof. By the late 1950s, his doctors recommended that he be transferred from Glin immediately, because he was in danger of having a nervous breakdown if he had to stay there.
There were reservations about Br Jesper from his early days in the Congregation. The Superior General wrote to him in the mid-1930s and drew his attention to a trait that cast doubt on his suitability to take perpetual vows. He reprimanded him for being: altogether too strict and harsh in your dealings with your pupils. It would appear that you are subject to moods, being at the one time rather depressed and gloomy and at others jubilant and vivacious ... Possibly in class these variations are manifested by a want of uniformity in your dealings with the boys, treating them indulgently at one time and again with great severity ... Harshness towards pupils is out of date. A good educator is never severe towards those he is training. Severity alienates the sympathy of the pupils with their teacher and loses to him their cooperation, the most powerful means he has for success.
Nevertheless, Br Jesper took his final vows shortly after this reprimand.
Br Jesper completed an internal Christian Brothers’ questionnaire in 2001 regarding life in Glin. He stated that there was ‘strong discipline’ in the School but that it was not as tough as discipline in day schools, ‘It certainly was not hard’. He denied that the boys were beaten regularly and ‘it would have been an exception arising out of a grave infringement of the rules that they would be in any way chastised’. He conceded that the leather was used, but asserted that he had dispensed with its use shortly after his arrival in Glin. He denied any allegations of physical abuse made against him, and indicated that he would be surprised if similar allegations against his colleagues were true.
