I am writing a non-fiction, somewhat historic, book and I want to dedicate it to a person who did pioneer work on Education in Science in Brazil. She has passed away recently and was professionally related to one of the main characters in my book; a famous scientist. Many years ago, she worked in the high school where I studied and even invited that scientist to give a informal talk to us students.
Since she is not well known, I wanted to write a short biography of her and include it in the backmatter (bibliography/index/appendix) of the book. Is this appropriate?
