Blondel (1618-1686), brilliant mathematician, architect engineer, and topographer, was admitted to the Royal Academy of Sciences in 1669. He became director of the Royal Academy of Architecture in 1671, was appointed director of public works for the city of Paris by Louis XIV in 1672, and in 1673 became mathematics tutor to the dauphin. Earlier, “during his infantry service, Blondel had been amazed at the crude methods of the French bombardiers,” and devised practical rules for determining the angle of a mortar sometime in 1677.
The printing of Blondel’s solution in L'ART DE JETTER LES BOMBES “was delayed by order of Louis XIV, who hardly cared to have the enemy profit by it. The French gunners, however, paid no attention to it until 1731 …” (DSB).
