Stravinsky struggled financially during this period. Russia (and its successor, the USSR) did not adhere to the Berne Convention and this created problems for Stravinsky when collecting royalties for the performances of all his Ballets Russes compositions. Stravinsky blamed Diaghilev for his financial troubles, accusing him of failing to live up to the terms of a contract they had signed. He approached the Swiss philanthropist Werner Reinhart for financial assistance while he was writing L'Histoire du soldat (The Soldier's Tale). Reinhart sponsored and largely underwrote its first performance, conducted by Ernest Ansermet on 28 September 1918 at the Théâtre Municipal de Lausanne. In gratitude, Stravinsky dedicated the work to Reinhart and gave him the original manuscript.
