Extractions: Philippe de la Hire was educated as an artist and became skilled in drawing and painting. He visited Italy where he spent four years developing his artistic skills and learning geometry. The interest in geometry arose from his study of perspective in art. Much influenced by the work of Desargues , La Hire worked on conic sections which he treated projectively. He published his first work on conic sections in 1673. In 1675 he published a more comprehensive work on conic sections Sectiones conicae which contained a description of Desargues projective geometry . In 1708 he calculated the length of the cardioid. Other topics to which he made important contributions included astronomy, physics and geodesy. In astronomy he installed the first transit instrument in the Paris Observatory. He also produced tables giving the movements of the Sun, Moon and the planets. He did much work on surveying, in particular taking measurements of the French coastline. He designed an instrument to find the level at a site. He was also a major contributor to a project to map France.

Scientific Disciplines Primary: Astronomy, Mathematics, Mechanics Subordinate: Zoology, Physiology, Meteorology After his father's death he spent four years in Venice where he developed his artistic talent and studied classical geometry. Upon his return to France he was active primarily as an artist. He formed a friendship with Abraham Bosse, Desargues last disciple, who asked La Hire to solve a problem in stonecutting. In 1673 La Hire published Nouvelle methode en géometrie pour les sections des superficies coniques et cylindriques from his research in constructing conic sections. Twelve years later he published a much more extensive work, Sectiones conicae, through which Desargues' projective geometry became known.

Z Mathematician, astronomer, physicist, naturalist, and painter, b. in Paris, 18 March, 1640; d. in Paris, 21 April, 1718; was, as Fontenelle said, an academy in himself. His father, Laurent de La Hire, (1606-1656), was a distinguished artist. Philippe first studied painting in Rome, where he had gone for his health in 1660, but on his return to Paris, soon devoted himself to the classics and to science. He showed particular aptitude for mathematics, in which subject he was successively the pupil and associate in original investigation of Desargues. In 1678, he was made a member of the Academy of Sciences, section of astronomy. Beginning in 1679, in connexion with the construction of a map for the Government, he made extended observations in Brittany, Guienne, Calais, Dunkirk, and Provence. In 1683, he continued the principal meridian north from Paris, Cassini The chief contributions of La Hire were in the department of pure geometry. Although familiar with the analytic method of Descartes , which he followed in treatises published in 1679, his most important works were developed in the method of the ancients. He continued the work of Desargues and of

Elfenbeindrechsler De La Hire (Hière), Gabriel Philippe Geb. 1677; gest. 1719. Durch seinen Beruf als Architekt mit der Geometrie vertraut, beschäftigte ihn vor allem das Unvermögen, bei Polyedern die Ecken exakt drechseln zu können. Eine von ihm konstruierte Vorrichtung, die winkelgerechte und seitenparallele Arbeiten auf der Drehbank ermöglicht, wurde von ihm an der königlichen Akademie vorgestellt, deren Mitglied er war. (Bibl., DE LA HIRE, 1719, S.320). Es wird berichtet, dass das von De la Hire in Verbindung mit einer Drehbank zu verwendende Werkzeug für winkelgerechte und seitenparallele spanabhebende Arbeiten von Nartoff, der in Russland als Kunstdrechsler tätig war, zu einem eigenständigen Gerät weiterentwickelt wurde. (Bibl., K. MAURICE, 1985, S. 100)
