1890 Russell enters Trinity College, Cambridge University, and begins studies in applied mathematics and mathematical physics (e.g., calculus, optics, astronomy, statics, hydrostatics, dynamics). In February, he is elected to the Apostles, an intellectual secret society at Cambridge.
1893 Upon coming of age in May, Russell inherits £20,000. In July, he begins a year of philosophical studies focusing on ethics, metaphysics, and 17th-century philosophy.

1897 In January, Russell publishes a review of Louis Couturat’s book on Cantorian set theory, De l’Infini Mathématique (1896). In May, he reads Hermann Lotze’s Metaphysik (1879) and publishes his fellowship thesis as An Essay on the Foundations of Geometry. In “Seems Madam? Nay, It Is,” a talk given in December to the Apostles, he begins to break with idealism.
1898 Russell’s grandmother dies in January. In January and February, he attends John McTaggart’s lectures on Lotze. Throughout the year, Russell has frequent discussions with G. E. Moore, leading to their adoption of realism and break with idealism. In September, Russell reads Alexius Meinong’s Über die Bedeutung des Weberschen Gesetzes (1896). He subsequently travels to Italy, Germany, and France, visiting Couturat in November.
1899 Beginning in January, Russell lectures on G. W. Leibniz at Trinity College. In April, he publishes his review of Meinong’s Über die Bedeutung and responds to Henri Poincaré’s review of his Essay on the Foundations of Geometry. In July, he again studies Cantorian set theory.

Meanwhile, Russell reads volume 1 of Gottlob Frege’s Grundgesetze der Arithmetik (1893). In December, he discovers what is now called Cantor’s paradox of the greatest cardinal, which leads him to give a first formulation of a paradox of sets. Russell remains silent on the matter for over a year, except to Alfred North Whitehead. He completes a draft of The Principles of Mathematics.
1901 In June, Russell begins to work with Whitehead on “Finite and Infinite Cardinal Numbers,” a paper that anticipates Principia Mathematica (1910-1913) by treating cardinal numbers within the logic of relations. He publishes the important “Logic of Relations” in July and November.
