Is classical liberal history devoid of gay people? Given the prominence of gay people in the modern libertarian movement, it would be odd indeed if this were the situation. But, as it often the case with the histories of the private lives of individuals living in intolerant eras, it is harder to document such relationships. I would like to suggest two gay couples in the history of classical liberal thought. The first is that of Frederic Bastiat (1801-1850) and Felix Coudroy (unknown to me). The second is that of Etienne de la Boétie (1530-1563) and Michel de Montaigne (1533-1592).
I'm relatively sure, that Frederic Bastiat was probably gay. He married, but in a very odd way. The woman was wealthy and he needed the funds at the time for the family property. They married and then basically never saw one another after that, she pretty much disappears from his life. I believe he may have written her some notes now and then, but they never live together as man and wife. It was a property arrangement, as was often the case for the more wealthy individuals of the time.
