• Hilbert arbeitete nacheinander in ganz verschiedenen Gebieten der Mathematik jedes dieser Gebiete, und dadurch die ganze Mathematik hat er mit seiner Denkweise geprägt. Die Art, wie ein heutiger Mathematiker über seine Wissenschaft denkt und in ihr arbeitet, geht in großem Maß auf Hilbert zurück. Klarheit der grundlegenden Prinzipien war für Hilbert ein zentrales Gebot; durch Klarheit, gekoppelt mit einer außergewöhnlichen Phantasie, ist er tief in das Wesen mehrerer Gebiete der Mathematik eingedrungen. ...

• David Hilbert.
• David Hilbert attended the gymnasium in his home town of Königsberg. ... One of Hilbert's friends there was Minkowski, who was also a doctoral student at Königsberg, and they were to strongly influence each others mathematical progress. ...
• In 1884 Hurwitz was appointed to the University of Königsberg and quickly became friends with Hilbert, a friendship which was another important factor in Hilbert's mathematical development. Hilbert was a member of staff at Königsberg from 1886 to 1895, being a Privatdozent until 1892, then as Extraordinary Professor for one year before being appointed a full professor in 1893. ...
• In 1892 Schwarz moved from Göttingen to Berlin to occupy Weierstrass's chair and Klein wanted to offer Hilbert the vacant Göttingen chair. ... Klein was probably not too unhappy when Weber moved to a chair at Strasbourg three years later since on this occasion he was successful in his aim of appointing Hilbert. So, in 1895, Hilbert was appointed to the chair of mathematics at the University of Göttingen, where he continued to teach for the rest of his career. ...
• Hilbert's eminent position in the world of mathematics after 1900 meant that other institutions would have liked to tempt him to leave Göttingen and, in 1902, the University of Berlin offered Hilbert Fuchs' chair. Hilbert turned down the Berlin chair, but only after he had used the offer to bargain with Göttingen and persuade them to set up a new chair to bring his friend Minkowski to Göttingen. ...
• Hilbert's first work was on invariant theory and, in 1888, he proved his famous Basis Theorem. ... Hilbert himself tried at first to follow Gordan's approach but soon realised that a new line of attack was necessary. ...
• In 1893 while still at Königsberg Hilbert began a work Zahlbericht on algebraic number theory. ... The Zahlbericht (1897) is a brilliant synthesis of the work of Kummer, Kronecker and Dedekind but contains a wealth of Hilbert's own ideas. ... not really a Bericht in the conventional sense of the word, but rather a piece of original research revealing that Hilbert was no mere specialist, however gifted. ... Hilbert's work in geometry had the greatest influence in that area after Euclid. A systematic study of the axioms of Euclidean geometry led Hilbert to propose 21 such axioms and he analysed their significance. ...
