of the financial crisis of 2007–08. Personal life Relationships Keynes's early romantic and sexual relationships were exclusively with men. Keynes had been in relationships while at Eton and Cambridge; significant among these early partners were Dilly Knox and Daniel Macmillan. Keynes was open about his affairs, and from 1901 to 1915 kept separate diaries in which he tabulated his many sexual encounters. Keynes's relationship and later close friendship with Macmillan was to be fortunate, as Macmillan's company first published his tract Economic Consequences of the Peace. Attitudes in the Bloomsbury Group, in which Keynes was avidly involved, were relaxed about homosexuality. Keynes, together with writer Lytton Strachey, had reshaped the Victorian attitudes of the Cambridge Apostles: "since [their] time, homosexual relations among the members were for a time common", wrote Bertrand Russell. The artist Duncan Grant has been described as "the supreme male love of Keynes's life", and their sexual relationship lasted from 1908 to 1915. Keynes was also involved with Lytton Strachey, though they were, for the most part, love rivals rather than lovers. Keynes had won the affections of Arthur Hobhouse, and as with Grant, fell out with a jealous Strachey for it. Strachey had previously found himself put off by Keynes, not least because of his manner of "treat[ing] his love affairs statistically". Political opponents have used Keynes's sexuality to attack his academic work. One line of attack held that he was uninterested in the long-term ramifications of his theories because he had no children. Keynes's friends in the Bloomsbury Group were initially surprised when, in his later years, he began pursuing affairs with women, demonstrating himself to be bisexual. Ray Costelloe (who later married Oliver Strachey) was an early heterosexual interest of Keynes. In 1906, Keynes had written of this infatuation that, "I seem to have fallen in love with Ray a little bit, but as she isn't male I haven't [been] able to think of any suitable steps to take." Marriage In 1921, Keynes wrote that he had fallen "very much in love" with Lydia Lopokova, a well-known Russian ballerina and one of the stars of Sergei Diaghilev's Ballets Russes. In the early years of his courtship, he maintained an affair with a younger man, Sebastian Sprott, in tandem with Lopokova, but eventually chose Lopokova exclusively. They were married in 1925, with Keynes's former lover Duncan Grant as best man. "What a marriage of beauty
