António Cabreira


Portuguese mathematician, polygraph and publicist notable for his vast published work on an extensive variety of different fields (among them mathematics and geometry — one of his papers posited a solution for the problem of squaring the circle, as well as that of circling the square, cubing the sphere, and sphering the cube — mechanics, astronomy, literature, art, anthropology, philosophy, sociology, history, archaeology, insurance, jurisprudence, politics, and military organisation), and for spearheading the creation of many ephemeral learned societies, chief among them the Academy of Sciences of Portugal (created in 1907 after dissension with the Lisbon Academy of Sciences) and the António Cabreira Institute (established in 1919).

A member of the aristocratic Cabreira family, António Cabreira was a claimant to the Miguelist noble titles of Count of Lagos and Viscount of Vale da Mata, which he used. He died in Lisbon on 21 November 1953 at age 85.
