query: Who is considered the father of geometry?
passage: Euclid
Euclid (/ˈjuːklɪd/; Ancient Greek: Εὐκλείδης – Eukleídēs, pronounced[eu̯.klěː.dɛːs]; fl. 300 BC), sometimes given the name Euclid of Alexandria[1] to distinguish him from Euclides of Megara, was a Greek mathematician, often referred to as the "founder of geometry"[1] or the "father of geometry". He was active in Alexandria during the reign of PtolemyI (323–283 BC). His Elements is one of the most influential works in the history of mathematics, serving as the main textbook for teaching mathematics (especially geometry) from the time of its publication until the late 19th or early 20th century.[2][3][4] In the Elements, Euclid deduced the theorems of what is now called Euclidean geometry from a small set of axioms. Euclid also wrote works on perspective, conic sections, spherical geometry, number theory, and rigor.
passage: Raoul Blanchard
Raoul Blanchard is considered the father of modern geography in Québec. Thanks to him and his love for the French part of Canada [not neutral], Quebec has many books on geography. To thank him for this contribution, the Quebec Geographical Names Committee gave its name to a mountain of 1158 meters, the highest peak in the Laurentians, and the Department of Geography at the University of Montreal has honored giving its name to its largest classroom.
