Eva Kotchever (1891 – 19 December 1943), known also as Eve Adams or Eve Addams, born as Chawa Złoczower, was a Polish-Jewish émigré librarian and writer, who is the author of Lesbian Love and from 1925 to 1926 ran a popular, openly lesbian literary salon in Greenwich Village, Lower Manhattan, called Eve's Hangout. It closed after Eva was convicted and jailed for obscenity and disorderly conduct, which resulted in her deportation to Poland in 1927. She was later arrested in France in 1943 and deported to the Auschwitz concentration camp on 17 December, where she was murdered two days later on 19 December.

Chawa Zloczower was apparently born on 27 June 1891 in Mława, Poland, although records differ as to her exact birth date. She was the eldest of seven children of Mordechai and Miriam Zloczower. She was remembered by her family as the oldest sister who was "the right hand" of their mother. She would later testify that she attended "primary school" in Mława and "graduated in Plotzk". She was able to speak seven languages.

At age 20, Eva emigrated to the United States through Ellis Island, New York, on the S.S. Vaderland in 1912, sailing from Antwerp, Belgium. She began using the English version of her name, Eve, and dressed in men's clothing. She became involved in the anarchist movement, distributing publications, attending rallies and befriending anarchists from Mother Earth circles such as Emma Goldman, Alexander Berkman, Ben Reitman and Henry Miller.

On 21 February 1918, Eve, as "Eve Zlotchever," wrote a fervid fan letter to actress Fania Marinoff, who starred in the free-love play, Karen. Eve later became a cross-country traveling saleswoman of leftist periodicals, such as Mother Earth and The Liberator. By 1919, she was under surveillance by the "Radical Division" of the Bureau of Investigation, run by J. Edgar Hoover, because she was considered an "agitator".

From 1921 to 1923, Eve settled in Chicago, where she continued to sell Der Groyser Kundes and offered Russian lessons. For about eight months she ran with her partner, Swedish painter Ruth Norlander, a tea room named The Gray Cottage in Chicago, at 10 E Chestnut St, a literary salon that also served as a "refuge for gay people," according to the New York Times. Norlander (born Ruth Olson in 1889) exhibited two paintings, including one called Nudes in 1922 Chicago "No-Jury Exhibit," perhaps portraying Eve, who used to pose for Norlander.

In 1923, Eve returned to New York, and signed a declaration of intention to become a US citizen. In February 1925, she wrote and published in 150 copies "for private circulation only" of Lesbian Love (written under the name Evelyn Adams), a collection of short stories describing lives of women of the lesbian community. In March 1925, she opened Eve's Hangout, also known as Eve Addams' Tearoom in Greenwich Village. The only source that mentions a famous sign that allegedly read: "Men are admitted, but not welcome" is a 1926 article from Variety, which accused Adams of being financed by "a ring of rich women cultists" and inviting "mannish" women preying on girls. This led to Adams' biographer Jonathan Ned Katz to claim that the sign "probably never existed".

She was arrested by New York City's Vice Squad for obscenity and disorderly conduct after undercover police detective Margaret Leonard entered Eve's Hangout and was shown Lesbian Love. Leonard said Kotchever made overt sexual advances to her. After a year in jail, where she met Mae West, at Jefferson Market Prison, she was deported to Poland in December 1927.

Eve lived in Warsaw, Gdańsk, and Sopot, writing to her friends in letters about the low wages and antisemitism in Poland. She regularly corresponded with Ben Reitman, even after her exile to Europe. In 1930 she moved to Paris, where she wrote "a group of prison stories" planned to be published in The New Review (the journal ceased publication before their scheduled date). In Paris, she made a living by selling "dirty" books (such as works by James Joyce, Henry Miller, Anaïs Nin and D. H. Lawrence) to American tourists. She met some of those artists (Henry Miller, June Miller, and Anaïs Nin), all regulars of Le Dôme Café, called Dômiers, in the bohemian neighborhood of Montparnasse. Meanwhile, in America exaggerated rumours about Eve Adams circulated, claiming that in Paris, she ran a bookstore and a café named Le Boudoir de l'Amour in Montmartre (Brevities, 16 November 1931), and that she actively supported the Second Spanish Republic, against the regime of General Francisco Franco. There is no factual evidence to those claims.
