Answer the following question: Given the following context:  Elgar was knighted at Buckingham Palace on 5 July 1904. The following month, he and his family moved to Plâs Gwyn, a large house on the outskirts of Hereford, overlooking the River Wye, where they lived until 1911. Between 1902 and 1914, Elgar was, in Kennedy's words, at the zenith of popularity. He made four visits to the US, including one conducting tour, and earned considerable fees from the performance of his music. Between 1905 and 1908, he held the post of Peyton Professor of Music at the University of Birmingham. He had accepted the post reluctantly, feeling that a composer should not head a school of music. He was not at ease in the role, and his lectures caused controversy, with his attacks on the critics and on English music in general: "Vulgarity in the course of time may be refined. Vulgarity often goes with inventiveness ... but the commonplace mind can never be anything but commonplace. An Englishman will take you into a large room, beautifully proportioned, and will point out to you that it is white – all over white – and somebody will say, 'What exquisite taste'. You know in your own mind, in your own soul, that it is not taste at all, that it is the want of taste, that is mere evasion. English music is white, and evades everything." He regretted the controversy and was glad to hand on the post to his friend Granville Bantock in 1908. His new life as a celebrity was a mixed blessing to the highly strung Elgar, as it interrupted his privacy, and he often was in ill-health. He complained to Jaeger in 1903, "My life is one continual giving up of little things which I love." Both W. S. Gilbert and Thomas Hardy sought to collaborate with Elgar in this decade. Elgar refused, but would have collaborated with George Bernard Shaw had Shaw been willing.Elgar's principal composition in 1905 was the Introduction and Allegro for Strings, dedicated to Samuel Sanford, professor at Yale University. Elgar visited America in that year to conduct his music and to accept a doctorate from Yale. His next...  answer the following question:  In what specific year did Elgar visit America to conduct his music and accept a doctorate from Yale?
