Was Ruth Nichols the aviatrix a Lesbian?

No, it was even rumored that she was heavily involved with well known California arist of the time Xavier Martinez, as well as artist Ernest Pexitto. Harriet's reason for never getting married was that she had devoted her life to her career, and in those days (Early 1900's) you had a social choice of career or being a housewife. We don't know much about Harriet's personal or romantic life, but being the stunningly beautiful, daring, unconventional woman that she was, she certainly would have had suitors lining up outside her door, was an active and much-sought-after participant in New York City high society of the Edwardian Era, within the constraints of the 1900's, very likely did have her share of romantic attachments.
