Paul de Clermont

Paul de Clermont was a French mathematician and military engineer of the seventeenth century who served in the French Army as artillery commissary at Strasbourg. His book on practical geometry, La geometrie pratique de l'ingenieur, ou L'art de mesurer, printed at Strasbourg in 1693, was a reference work reprinted for sixty years. A second work, L'arithmetique militaire, ou L'arithmetique pratique de l'ingenieur et de l'officier, appeared in Paris in 1733. Both books are written in French for engineers and officers who needed methods of measuring and calculating in the field.
