Marjorie Jackson (Nelson) first gained fame when she defeated reigning Olympic 100m and 200m champion Fanny Blankers-Koen a number of times in 1949, earning her the nickname 'the Lithgow Flash', after the New South Wales town where she lived. Jackson won two Olympic gold medals and seven Commonwealth Games gold medals. Between 1950 and 1954 she won every state and Australian title she contested for the 100yds, 100m, 220yds and 200m sprints (six in total). During her athletic career she broke world sprint records on ten occasions.
