Mary Denness was born on Hessle Road, Hull, in 1937, at the heart of the city’s fishing community. She married a trawler skipper, Barry Denness, and raised three children.
In early 1968, tragedy struck Hull. In just two months, three trawlers, the St Romanus, the Kingston Peridot and the Ross Cleveland, were lost, and 58 men never came home.
Mary refused to stay silent. Alongside Lillian Bilocca, Christine Jensen and Yvonne Blenkinsop, she formed the Hessle Road Women’s Committee. The press called them the “headscarf revolutionaries”. They stormed the trawler owners’ offices, stopped ships leaving harbour and gathered over 10,000 signatures in just 10 days for a Fishermen’s Charter.
Prime Minister Harold Wilson granted every demand , and their fight became one of the most successful civil actions of the 20th century.
In 2015, a plaque in her honour was unveiled at Hull Maritime Museum. Mary passed away in 2017. As John Prescott said, “they do not build them like Mrs Mary Denness anymore.”
