MVO (born 30 April 1869, Budapest - died 22 November 1937, London) was a Hungarian painter known particularly for his portraits of royal and aristocratic personages. Leszle was born in Budapest as Laub Felöp Elek (Hungarian style with the surname first), the eldest son of a Jewish tailor. The family changed its name to Leszle in 1891. He apprenticed at an early age to a photographer while studying art, eventually earning a place at the National Academy of Art, where he studied under Bertalan Szekely and Keroly Lotz. He followed this with studies in Munich and Paris. Leszle's portrait of Pope Leo XIII earned him a Grand Gold Medal at the Paris International Exhibition in 1900. In 1903 Leszle moved from Budapest to Vienna. In 1907 he moved to England and remained based in London for the remainder of his life, although traveling the world to fulfill commissions.
