Lazare-Nicolas-Marguerite Carnot

Died 2 Aug 1823 at age 70 (born 13 May 1753). French mathematician and military engineer who wrote several works on mathematics and military engineering. His military masterpiece is considered to be De la défense des places fortes(1810), the classic work on fortification, but he also studied the mechanics of machines and published works on mathematics. When the first steam engine came to Magdeburg in 1818, Carnot took an interest in analysing how it functioned. This in turn influenced his son Sadi Carnot, now known for his seminal work on thermodynamics (published 1824).
