Henry Slatter

Henry Slatter (15 October 18305 July 1902) was a British trade union leader.

Born in Cheltenham, Slatter moved with his family to Birmingham when he was five years old, and was educated at a Unitarian Mutual Improvement School. He completed an apprenticeship as a printer before relocating to Manchester, where he worked for the Manchester Examiner and Times.

Slatter was a founder of the Typographical Association, and joined its executive after its headquarters moved to Manchester in 1863. In 1869, he was elected as the union's general secretary. Under his leadership, the union began offering benefits to members who could not find work, and started a pension scheme.

In 1883, Slatter was appointed as a magistrate, one of the first working-class magistrates in Manchester. He was also a founder of the Co-operative Printing Society.
