Angela Anaïs Juana Antolina Rosa Edelmira Nin y Culmell, known professionally as Anaïs Nin was a diarist, essayist, novelist, and writer of short stories and erotica.

Nin was a prolific diarist from her childhood until her death. Her diaries have left us with detailed information about her marriages with Hugh Parker Guiler and Rupert Pole, and her many affairs. Her diary also talks about her desire for Henry and June Miller. The portion of her diary describing her relationship with the Millers was later published as Henry and June (1986).

She was clearly having a passionate affair with Henry Miller, but was more circumspect when she talked about her feelings for June. She talked about her attraction to June, although she only describes brief kisses and touches with June. This is in stark contrast to her graphic descriptions of her sex with Henry Miller. 

Nin went on to base characters in her novels House of Incest (1936) and A Spy in the House of Love (1954) on June Miller.

Nin is hailed by many critics as one of the finest writers of female erotica. She was one of the first women known to explore fully the realm of erotic writing, and certainly the first prominent woman in the modern West known to write erotica. 

Faced with a desperate need for money, Nin, Henry Miller, and some of their friends began in the 1940s to write erotic and pornographic narratives for an anonymous "collector" for a dollar a page, somewhat as a joke.[1] Nin considered the characters in her erotica to be extreme caricatures and never intended the work to be published, but changed her mind in the early 1970s and allowed them to be published as Delta of Venus (1977) and Little Birds (1979).[2]
