With thanks to Dominic Sheridan for bringing Marie Louise Mack to my attention.
Louise was Australian - born in Hobart and educated in Sydney where she moved with her family. Louise went to London to work in 1901. She was the first woman journalist to report first hand as a war correspondent from Belgium in 1914.
