"Unequalled as a teacher he commanded the highest admiration by the masterly way in which he exposed and discussed the most intricate problems, and many scientists of recognized authority were known to take their places on the benches among his pupils. His treatises and calculations recommended themselves by an extreme simplicity, at the same time being classic for their completeness and elegance. In his social intercourse he was amiable and engaging, and in return was universally esteemed and honoured. His energy was remarkable, and the unflinching resolution with which he executed a task, which failing health continually menaced with frustration, cannot be contemplated without admiration. Naturally of a reserved disposition, his habits were simple and his manners unassuming, nor was he ever known to show the slightest vanity or self-esteem on account of the numerous distinctions which were showered upon him; love of truth was his only passion. Three things he always cherished and treasured in the midst of his restless activity: the love of his country, his family, and his religion."
