William Henry Carr (1855 – 27 October 1953) was a British trade unionist and political activist.
Born in the East End of London, Carr grew up in Bacup where he began working in a mill at the age of eleven.
[1] In 1888, Carr was elected as the secretary of the South East Lancashire Provincial Card and Blowing Room Operatives' Association.
His union, the Cardroom Amalgamation of which it formed a part, and the United Textile Factory Workers' Association (UTFWA), which brought together most unions in the industry, all supported his candidacy in Stalybridge for the January 1910 general election, but this was ultimately abandoned due to a lack of local support.
[4] Carr was re-adopted as Labour's Prospective Parliamentary Candidate for Preston following the election, but the UTFWA withdrew its support in 1913, leading the Cardroom Amalgamation to leave in protest.
