Not sure if this is the best place to ask this, but I don't know if it would be better off in /r/poetry.

I'm doing a research paper about Hart Crane and his impact on the literary world. I think I'll say that since he was openly gay, he helped the modernist movement and the shift towards acceptance of gay people. But my question is, was he actually openly gay? I know he died after making sexual advances toward a man on the ship he was on, but I don't know if he was open about it before then.
