Jean-Joseph Thonissen

"Thonissen was an intrepid worker, a firm Christian, an upright and simple man, with just a touch of artless vanity, though sometimes brusque in manner and given to occasional outbursts. He was one of the most important members of the faculty of law at Louvain and he will be chiefly remembered in the sphere of penal law, where his name is destined to survive."
