Philip Alexius de László, MVO (30 April 1869 – 22 November 1937) was a Hungarian painter known particularly for his portraits of royal and aristocratic personages. In 1900, he married Lucy Guinness of Stillorgan, County Dublin, and became a British subject in 1914.
László was born in humble circumstances in Budapest as Laub Fülöp (Hungarian style with the surname first), the eldest son of Jewish parents, Adolf and Johanna Laub, a tailor and seamstress, respectively. Fülöp and his younger brother Marczi changed their surname to László in 1891. He was 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 Székely and Károly Lotz. He followed this with studies in Munich and Paris. László's portrait of Pope Leo XIII earned him a Grand Gold Medal at the Paris International Exhibition in 1900. In 1903 László moved from Budapest to Vienna. In 1907 he moved to England and remained based in London for the remainder of his life, although endlessly travelling the world to fulfill commissions.
In 1900, László married Lucy Madeleine Guinness, a member of the banking branch of the Guinness family and a sister of Henry Guinness. They had first met in Munich in 1892, but for some years had been forbidden to see each other. The couple had six children and 17 grandchildren.
László's patrons awarded him numerous honours and medals. In 1909 he was invested MVO by Edward VII. In 1912 he was ennobled by King Franz Joseph of Hungary; his surname then became "László de Lombos", but he soon was using the name "de László".
Despite his British citizenship, his marriage and five British sons, de László was interned for over twelve months in 1917 and 1918 during the First World War. He was exonerated and released in June 1919. Due to overwork de László suffered heart problems for the last years of his life. In October 1937 he had a heart attack and died a month later at his home in Hampstead, London.
In 1939, Portrait of a Painter. The Authorized Life of Philip de László by Owen Rutter, written in conjunction with de László, was published. In 2010 Yale University Press published De László, His Life and Art by Duff Hart-Davis and Dr. Caroline Corbeau-Parsons. His reputation still remains largely as a society portrait painter, but well numbered amongst his sitters were industrialists and scientists, politicians and painters, men and women of letters and many other eminent, as well as ordinary, people. Family members and a team of editors are compiling a catalogue raisonné published online and in progress. His oeuvre currently numbers almost 4,000 works, including drawings.
