Adelaide Laetitia Miethke began training as a teacher in 1899, and soon became active in women teachers' and union affairs. She was the first woman vice-president of the South Australian Public School Teacher's Union in 1916, and in 1924 gained both her Arts degree and her position as the first female inspector of high schools. She was South Australian state president of the National Council of Women from 1934, and national president, 1936-1942. Miethke was appointed as an Officer of the Order of the British Empire (Civil) on 1 February 1937 for her role as President of the South Australian Women's Centenary Council, particularly in organising the Pageant of Empire on 27-28 November 1936. Miethke went on to work with the Royal Flying Doctor Service, and establish the School of the Air for outback children.
