The son of a linen manufacturer, this Scottish-born industrialist was first apprenticed to James Russell, a draper at Cupar, Fife. Having accumulated sufficient capital in Glasgow, he moved to Ireland in 1837 and established short-lived businesses in Belfast and Cork. He achieved more success as a partner of Cannock and White, a large firm of Cork drapers which was, in 1865, renamed Arnott & Company.
Arnott’s connections with small businesses in Kinsale, his generosity to the Neopolitan exiles,
Generally regarded as a moderate and ‘very mild and inoffensive politician’, Arnott’s primary concern was the care of destitute children. In August 1859, having witnessed the conditions prevailing in the Cork Union Workhouse, he published his findings and moved for a select committee to inquire into the alleged excess of mortality of children in Irish workhouses.
Fuelled by successful speculations on the Stock Exchange, Arnott further expanded his business interests, purchasing the Irish Times for just £35,000 in 1873 and the Belfast Northern Whig (for £17,500) in 1874. He turned the ailing Irish Times into the most prosperous newspaper in Ireland and an influential prop to the establishment in Ireland.
Arnott was an extremely methodical and painstaking businessman, being possessed of ‘a singularly retentive memory’ and outstanding mathematical ability (‘his big brainy head’ attesting to ‘the high order of intellectuality with which he was gifted’). Yet he was regarded as an amiable man, being ‘modest and unostentatious’ in his private life.
