By chance I came across a reference to Eliza Maud "Elsie" Inglis. In the First World War the War Office told her, "my good lady, go home and sit still". Instead she, with others, treated thousands of wounded soldiers. She did a lot more than that - see the wikipedia entry

Just wondering how many others there are!
Sorry for typo, cant change subject
