Morris Ernst (1888–1976) was an American lawyer and co-founder of the American Civil Liberties Union (ACLU).
Morris Leopold Ernst was born in Uniontown, Alabama, on August 23, 1888, to Carl and Sarah Bernheim Ernst. His father was born in what is now Czechoslovakia who worked as a peddler and shopkeeper. His mother graduated from Hunter College. The family moved to New York when Morris was two, and lived in several locations in Manhattan. He attended the Horace Mann School and graduated from Williams College in Williamstown, Massachusetts, in 1909. He studied law at night at New York Law School where he graduated in 1912 and was admitted to the New York bar in 1913.
Ernst practiced law in New York City and in 1915 co-founded the law firm of Greenbaum, Wolff & Ernst. In 1917, he helped found the National Civil Liberties Bureau, which later became the American Civil Liberties Union (ACLU).
In 1933, on behalf of Random House, he successfully defended James Joyce's novel Ulysses against obscenity charges, leading to its distribution in the U.S. He won similar cases on behalf of Radclyffe Hall's The Well of Loneliness and Arthur Schnitzler's Casanova's Homecoming.
In 1937, as attorney for the American Newspaper Guild, he argued successfully in the Supreme Court that it should uphold the constitutionality of the National Labor Relations Act (the Wagner Act) as applied to the press. The case established the right of media employees to organize labor unions.
Ernst was a strong supporter of J. Edgar Hoover and the FBI. In 1940, as head of the ACLU, he agreed to bar communists from employment there and even discouraged their membership, basing his position on a distinction between the rights of the individual and the rights of groups. In 1946, President Harry Truman appointed him to the President's Committee on Civil Rights.
He counted Justice Louis Brandeis as a close friend and later had close personal relationships with Presidents Franklin Roosevelt and Harry Truman and New York Governor Herbert Lehman. Besides politicians, he also was friendly with many cultural figures, including Edna Ferber, E. B. White, Groucho Marx, Michael Foot, Compton Mackenzie, Al Capp, Charles Addams, Grandma Moses, Heywood Broun, and Margaret Bourke-White.
In 1956, Jesús Galíndez, a critic of the regime of Rafael Trujillo in the Dominican Republic, disappeared, abducted from New York City, it was charged, by Trujillo's agents. Hired by Trujillo to investigate the affair, Ernst's resulting report cleared the Trujillo regime of involvement in Galindez's disappearance, but the FBI and the press remained unconvinced.
In 1912, he married Susan Leerburger, with whom he had a son who died in infancy and a daughter. Susan died in 1922. Ernst married Margaret Samuels in 1923, and together they had a son and a daughter. Margaret died in 1964. Ernst kept a summer home on Nantucket, Massachusetts, and enjoyed sailing small boats. He died at home in New York City on May 21, 1976. He was survived by his son, both daughters, and five grandchildren.
