Franco of Liège

Franco of Liège (died c. 1083) was an 11th-century mathematician who worked on squaring the circle. He was the scholaster of Saint Lambert's Cathedral, Liège.[1]

His De quadratura circuli, explaining his efforts to square the circle, was written around 1050.[2]

The musical treatise Quaestiones in musica, primarily ascribed to Rudolf of St Trond, has also been attributed to him.[3]
