I want to name Jennifer Finney Boylan.
For writing the book "She's not there: A life in two genders". I guess that her experience is not too uncommon for us trans persons but writing a book that captures so much of the things that only a trans-person will ever experience is quite uncommon. That book surely helped me realize who I actually am, and that I've been this way since forever, and I'm sure many of us has read the book and recognized almost everything.
May I suggest that we name but one role model in each post? And that we provide a bit of motivation as well (I think it is the motivation that is valuable for the readers)?
