Wadding, Ambrose (1583–1619), Jesuit and university teacher, was born 24 February 1583, the son of Walter Wadding and his wife, Anastatia Lombard, both of Waterford. He was an older brother of the famous Franciscan Luke Wadding (qv). Following the deaths of both his parents in 1602, Ambrose left Waterford to study philosophy in the Irish college at Salamanca for a year or two, before joining the Spanish military. However, after narrowly escaping death during a naval battle, he decided to become a priest and eventually joined the Jesuits, entering the novitiate of San Andrea in Rome on 11 January 1605. He studied philosophy there for a year and in 1606–7 travelled to the University of Ingolstadt in Germany to study theology for four years. He demonstrated great piety and showed an aptitude for mathematics and other related subjects.
In 1610 he was repetitor of metaphysics in Ingolstadt and vice-president of the major congregation of the Blessed Virgin, and a year later he was superior of the clerics in the college. Having completed his theology studies, he was appointed professor of physics in the University of Dilingen, Germany, in 1612. Over the next few years he held various professorships in the university, before settling as professor of ethics and Hebrew from 1615. At Dilingen he also administered a nearby hostel, St Jerome's, which housed students from religious orders. In October 1616 the Irish Jesuits requested his transfer to Ireland, but the Jesuits at Dilingen blocked this, saying that he was too important. Always in poor health, he died 22 January 1619 at Dilingen, leaving behind nine printed philosophical theses and a manuscript on moral theology. His early death was mourned by his academic colleagues, who greatly admired him for his learning.
