Nathan Ross Margold (1899 - December 17, 1947) was a Romanian-born American lawyer. He was a municipal judge in Washington, D.C., and the author of the 1933 Margold Report to promote civil rights for African-Americans through the courts. He was also a supporter of Native American civil rights and Native American sovereignty. In addition to his legal career, Margold is remembered as the father of adult film pioneer William Margold. Early life Nathan Ross Margold was born in Iași, Romania in 1899, to Wolf Margulies and Rosa Kahan. He was brought to the United States at age two. Growing up in Brooklyn, he graduated from City College of New York in 1919. Margold then attended Harvard Law School. He became the editor of the school's Law Review. He was a "protégé" of Felix Frankfurter, who interested him in working for social reforms and workers rights. Latter, during the New Deal era, former students of Frankfurter who joined the U.S. Federal government (including Margold) were collectively referred to as "Happy Hotdogs" invoking a pun on their mentor's name. Career After earning his law degree, Margold returned to New York City in 1923 and set up a private practice. From 1925 through 1927 Margold served as the assistant U.S. attorney for the Southern District of New York. In 1927 Margold married Gertrude Weiner (the couple would go on to have a son). Also in 1927, Felix Frankfurter persuaded Margold to return to his alma mater, the Harvard Law School, and teach Criminal Law. Harvard president A. Laurence Lowell opposed Margold, as he did not want another Jewish reformer on the faculty. Lowell's opposition was countered by law school dean Roscoe Pound who was a supporter of Frankfurter. Pound was forced to back down to Lowell after almost two years of pressure, and Margold lost his job. Margold returned to his private practice in New York City in 1928. From 1928 through 1929 Margold served as a special counsel for the New York Transit Commission. In 1930 he served as a legal adviser on Indian affairs for the Institute for Government Research. During this time Margold also wrote many articles for law journals and coedited Cases on Criminal Law. Due to Frankfurter's recommendation, the National Association for the Advancement of Colored People (NAACP) recruited Margold as a special counsel beginning from 1930 through 1933. In 1931, Margold wrote a book-length strategy (often referred
