Mary O'Brien

Mary O'Brien from Bootle operated a height-finder instrument in an anti-aircraft battery defending Liverpool during the Blitz. The May Blitz of 1941 devastated her home neighbourhood, destroying her family's house and killing several neighbours. Despite personal loss, she continued to serve with distinction, helping to direct fire against Luftwaffe bombers attacking the docks and city centre. She served throughout the war and later became a prominent campaigner for the recognition of women's wartime contributions.
