Paolo Deslanges (sometimes also spelled Delanges) (c. 1750 – 1810)[1] was an Italian military engineer and mathematician, and a member of the Academy of Sciences of Turin. As a geometer, he investigated the curve named after him, the Deslanges trisectrix.
Biography
Deslanges is believed to have been born around 1750 in Orzinuovi, a Lombard town in the Province of Brescia, northern Italy. From a very young age, he showed a great interest in applied mathematics, which led him to dedicate himself to the fields of hydrostatics and hydrodynamics. As a military engineer for the Republic of Venice, he reached the rank of captain, contributing through his studies to the regulation of the river network in the Venetian provinces. He became one of the first members of the "Italian Society" (Società Italiana), founded in Verona and later relocated to Modena, which published several of his works in its Memorie. In 1785, he was a mathematics professor at the military school of Verona,[2] and in 1793, he designed the fortification works for Fort San Pietro in Volta, at the mouth of the port of Malamocco.[3]
In addition to his hydrographic work, Deslanges analyzed other engineering problems (such as the stability of retaining walls, the strength of construction materials like wood and iron, and the influence of friction on machine performance). In the mathematical field, he studied the curve named after him, the Deslanges trisectrix, publishing a paper on it in 1783.[2]
He died in Orzinuovi in 1810.[1]
