Ervin Bossányi (3 March 1891 in Rigyica / Riđica, Austria-Hungary – 11 July 1975 in Eastcote in Greater London, England) was a Hungarian artist, who worked mainly in northern Germany until his emigration in 1934. He then started a new career as a notable stained glass artist in England.
Bossányi was born in a small village in southern Austria-Hungary and educated in Budapest. In World War I he was interned for five years in France. After the war he became a notable painter and sculptor in Lübeck and (1929) in Hamburg. A major work from this period is his fountain in Bad Segeberg. 1934 he left Nazi Germany for England. Here he specialized with remarkable success in stained glass. He made stained glass windows for the University of London (Goldsmith' Library in the Senate House Library), Tate Gallery ("The Angel Blesses the Women Washing the Clothes"), the Victoria and Albert Museum ("Noli me tangere"), as well as cathedral glass for the York Minster, the memorial chapel for President Woodrow Wilson in Washington National Cathedral in Washington D.C. and Canterbury Cathedral. He also created the windows in the chapel at Michaelhouse in South Africa, and the stained glass window at Uxbridge tube station in London.
