German mathematician David Hilbert is known as one of the most influential mathematicians of the nineteenth century. After graduation, David enrolled at the University of Konigsberg, studied mathematics, and was friends with Herman Minkowski, also a German mathematician. During his initial days, David taught mathematics at the University of Konigsberg and Gottingen. Mathematicians like Ernest Zermelo and Hermann Weyl were some of his well-known students. David had supervised the dissertation projects of more than 69 students; some of them later became prominent mathematicians. Wilhelm Ackermann, Otto Blumenthal, Richard Courant and Hugo Steinhaus are some of them. Later Hilbert listed more than 20 unsolved mathematical questions at the international Congress of Mathematicians which was held in Paris during the year 1900. Two years later, he was appointed as the co-editor of ‘Mathematische Annalen’, one of the leading mathematical journals of the time. His other work includes co-authoring ‘Grundlagen der Mathematik’ which is considered to be the follow-up book of ‘Principles of Mathematical Logic', written by Hilbert and Ackermann. His other famous book is ‘The Foundations of Geometry’. We have gathered a few of his quotes and sayings that relate to mathematics, rules, physics, spirit, man, numbers, religion, opinion and much more. .
