Florence Violet Granville was born in 1890 though some record suggest it may be as late as 1892. Her father is believed to have been English-born James Granville a miner, and his wife Marie Annie, née Giles. In 1894 Florence's mother now a widow married commercial traveler, George Wallace, and Violet subsequently adopted her step father's surname.
Florence Violet McKenzie OBE (née Granville) affectionately known as "Mrs Mac", was Australia's first female electrical engineer. She was the founder of the Women's Emergency Signalling Corps (WESC) and lifelong promoter for technical education for women.
At St Phillip’s Church of England, Auburn, Sydney on 31 December 1924, Florence Violet Wallace married Cecil Roland McKenzie, an electrical engineer with the Sydney County Council.
In early in 1939, Florence Violet McKenzie aided by her husband, formed the Women’s Emergency Signalling Corps, which ran free courses. When World War II began later that year, the McKenzies had already trained nearly a thousand women in signalling subjects. she would go on to train some two thousand more, a third of whom joined the forces. Corps members wore a dark green and gold uniform that she had designed. 14 of her women graduates formed the nucleus of the Women’s Royal Australian Naval Service, and Mrs Mac was consider an honorary WRAN, later serving as Patron of the Ex-WRANS Association. As the war continued the Women’s Emergency Signalling Corps role expanded and by August 1945 the school had also trained some twelve thousand men in Morse code, visual signalling and international code. The Air Force even appointed Mrs McKenzie as an honorary flight officer of the Women's Auxiliary Australian Air Force, so she could legitimately instruct Air Force personnel.
After the war the McKenzie’s school continued voluntarily teaching signalling courses, training 2450 civil airline crewmen and 1050 merchant navy seamen by 1952. The school never received official status but In 1950 Mrs McKenzie was appointed an O.B.E. before finally closing her school in 1955.
She passed away in May 1982 and is buried at the Northern Suburbs Memorial Gardens and Crematorium, North Ryde, New South Wales, Australia. Her beloved Cecil who was as much as 9 years her junior had passed away in 1958, and they had remained childless
