Miriam Ruth Moskowitz (June 10, 1916 – February 14, 2018) was an American schoolteacher who served two years in prison after being convicted for conspiracy as an atomic spy for the Soviet Union.

In 1950, during the McCarthy era and as part of the atomic spies prosecutions, Miriam Moskowitz was indicted for conspiring with Abraham Brothman and Harry Gold to obstruct justice.

Brothman, a chemical engineer, hoped to get into business with the Soviet Union by providing blueprints for industrial processes he’d already described in trade journals.

[2] Moskowitz's prosecution arose from an investigation into Soviet nuclear espionage into the Manhattan Project and related activities by which the United States developed atomic bombs.

In 1951, Abraham Brothman's conviction for obstruction of justice was reversed by the United States Court of Appeals for the Second Circuit on the ground that venue did not lie in the Southern District of New York.

[8] Roy Cohn was disbarred by the Appellate Division of the New York State Supreme Court for unethical conduct in 1986.
