John Field (26 July 1782 [?], baptized 5 September 1782 – 23 January 1837) was an Irish pianist, composer, and teacher. He was born in Dublin into a musical family, and received his early education there. The Fields soon moved to London, where Field studied under Muzio Clementi. Under his tutelage, Field quickly became a famous and sought-after concert pianist; together, master and pupil visited Paris, Vienna, and St. Petersburg. The Russian capital impressed Field so much that he eventually decided to stay behind when Clementi left, and from about 1804 was particularly active in Russia.
