text: In October 1932, Rachmaninoff began a demanding concert season that consisted of 50 performances. The tour marked the fortieth anniversary of his debut as a pianist, for which several of his Russian friends now living in America sent him a scroll and wreath in celebration. The frail economic situation in the US resulted in the composer performing to smaller audiences, and he lost money in his investments and shares. The European leg of this tour in 1933 saw Rachmaninoff celebrate his sixtieth birthday among fellow musicians and friends, after which he retreated to Villa Senar for the summer. In May 1934, Rachmaninoff underwent a minor operation and two years later, he retreated to Aix-les-Bains in France to improve his arthritis. During a visit to Villa Senar in 1937, Rachmaninoff entered talks with choreographer Michel Fokine about a ballet based on Niccolò Paganini that was to feature his rhapsody. It premiered in London in 1939 with the composer's daughters in attendance. In 1938, Rachmaninoff performed his Piano Concerto No. 2 at a charity jubilee concert at London's Royal Albert Hall to celebrate Henry Wood, founder of the Promenade concerts and an admirer of Rachmaninoff's who wanted him to be the show's only soloist. Rachmaninoff agreed, so long the performance was not broadcast on the radio due to his aversion to the medium.
  The 1939–40 concert season saw Rachmaninoff perform fewer concerts than usual, totalling 43 appearances that were mostly in the US. The tour continued with dates across England, after which Rachmaninoff visited his daughter Tatyana in Paris followed by a return to Villa Senar. He was unable to perform for a while after slipping on the floor at the villa and injuring himself. He recovered enough to perform at the Lucerne International Music Festival on 11 August 1939. It was to be his final concert in Europe. With World War II imminent, he returned to Paris two days later, where he, his wife, and two daughters were together for the last time before the composer left Europe on 23 August. With financial help from Rachmaninoff, Ivan Ilyin was able to pay the bail and settle in Switzerland. Rachmaninoff would support the Soviet Union's war effort against Nazi Germany from mid-1941 onwards, donating receipts from many of his concerts for the benefit of the Red Army.
