John Field (26 July 1782 [?], baptised 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, in particular with the immigrant Tommaso Giordani. 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. Ambiguity surrounds Field's decision to remain in the Russian capital, but it is likely that Field acted as a sales representative for the Clementi Pianos.
