History's Most Influential Lesbians?

So I need your help. I am working on a project for Women's History month. I want to create an exhibit of the most influential lesbians in history but I am having trouble narrowing down my list. And truth be told I know I am a bit biased. I know LGBT African-American history very well (I teach seminars on LGBT African-American history). However, when it comes to naming famous and influential non-black lesbians I am at a loss. I know Ellen and Portia de Rossi. That's it. So PLEASE PLEASE PLEASE give me your feedback. Who do you think are some of the most influential same-gender loving women in history?
