 Dutch writer Marie Anderson corresponded with Busch . More than fifty letters were exchanged between January and October 1875 in which they discussed philosophy , religion and ethics . Although only one Anderson letter survives , Busch 's letters are in manuscripts . They met in Mainz in October 1875 , after which he returned to Basserman at Heidelback in a " horrible mood " . According to several people at the time , Busch 's failure to find a wife was responsible for his conspicuous behaviour . There is no evidence that Busch had a close relationship with any woman after that with Anderson .
