Amelia Earhart’s prenuptial agreement written to George P. Putnam is pretty awesome:
You must know my reluctance to marry, my feeling that I shatter thereby chances in work which means most to me. I feel the move just now as foolish as anything I could do. I know there may be compensation but have no heart to look ahead.
I love that Earhart is so upfront with Putnam about how important her career is to her, and her reluctance to get married (and be monogamous). Putnam ended up doing everything he could to promote her career and get her endorsements—up until the day she disappeared. [via]
