Nellie Letitia McClung (born Helen Letitia Mooney), was a Canadian author, social activist, suffragette, and politician. She was a part of the social and moral reform movements prevalent in Western Canada in the early 1900s. Her great causes were women's suffrage and the temperance movement (well, one out of two ain't bad).
It was largely through her efforts that in 1916 Manitoba became the first province to give women the right to vote and to run for public office (though they all could still drink, yay!).
I would like to leave it there, but I cannot. McClung was a significant player in the then popular eugenics movement, and was responsible (in part) for the compulsory sterilisation of thousands of women.
Sometimes stuff is difficult.
