Jérôme Paul Bonaventure Alday (c.1763 – 1835) was a French violinist, composer and music publisher who spent most of his active career in Dublin, Ireland.
Alday was born in Perpignan[1] as a member of a musical family that included his father (whose first name is unknown), his elder brother François (c.1761 – after 1835) and the latter's sons Francisque and Ferdinand, all of whom became composers resident in Lyon.
In musical reference works, there is considerable confusion regarding the ascription of compositions to either of these four musicians as their names mostly appear as "Alday" only.
He appeared both as a soloist in violin concertos and as leader of orchestras including the Anacreontic Society (1819–1828),[5] of which he was secretary (1824–1830), and The Sons of Handel.
Alday made a name for himself as a violinist, composer, and successful business man in Irish musical life of the early 19th century.
