William O'Dwyer

William O'Dwyer was an Irish-American politician and diplomat who served as the 100th Mayor of New York City, holding that office from 1946 to 1950.

O'Dwyer was born in Bohola, County Mayo, Ireland and studied at St. Nathys College, Ballaghaderreen, County Roscommon. In 1907, O'Dwyer began to study for the priesthood at the Pontifical University of Salamanca, a Jesuit seminary in Spain, where he became fluent in Spanish. He later decided not to join the clergy, and emigrated to the United States in 1910. He sailed to New York as a steerage passenger on board the liner Philadelphia and was inspected at Ellis Island on June 27, 1910. He first worked as a laborer, then as a New York City police officer, while studying law at night at Fordham University Law School. He received his degree in 1923 and then built up a successful practice before serving as a Kings County (Brooklyn) Court judge. He won election as the Kings County District Attorney in November 1939 and his prosecution of the organized crime syndicate known as Murder, Inc. made him a national celebrity.

After losing the mayoral election to Fiorello La Guardia in 1941, O'Dwyer joined the United States Army for World War II, achieving the rank of brigadier general as a member of the Allied Commission for Italy and executive director of the War Refugee Board, for which he received the Legion of Merit. During that time, he was on leave from his elected position as district attorney and replaced by his chief assistant, Thomas Cradock Hughes, and was re-elected in November 1943.

In 1945, O'Dwyer received the support of Tammany Hall leader Edward V. Loughlin, won the Democratic nomination, and then easily won the mayoral election. At his inauguration, O'Dwyer celebrated to the song, "It's a Great Day for the Irish", and addressed the 700 people gathered in Council Chambers at City Hall: "It is our high purpose to devote our whole time, our whole energy to do good work...." He established the Office of City Construction Coordinator, appointing Park Commissioner Robert Moses to the post, worked to have the permanent home of the United Nations located in Manhattan, presided over the first billion-dollar New York City budget, created a traffic department and raised the subway fare from five cents to ten cents. In 1948, O'Dwyer received The Hundred Year Association of New York's Gold Medal Award "in recognition of outstanding contributions to the City of New York." In 1948, he received the epithets "Whirling Willie" and "Flip-Flop Willie" from U.S. Representative Vito Marcantonio of the opposition American Labor Party while the latter was campaigning for Henry A. Wallace.

Shortly after his re-election to the mayoralty in 1949, O'Dwyer was confronted with a police corruption scandal uncovered by the Kings County District Attorney, Miles McDonald. O'Dwyer resigned from office on August 31, 1950. Upon his resignation, he was given a ticker tape parade up Broadway's Canyon of Heroes in the borough of Manhattan. President Harry Truman appointed him U.S. Ambassador to Mexico. He returned to New York City in 1951 to answer questions concerning his association with organized crime figures and the accusations followed him for the rest of his life. He resigned as ambassador on December 6, 1952, but remained in Mexico until 1960.

He helped organize the first Israel Day Parade, along with New York's Jewish community.

O'Dwyer died in New York City on November 24, 1964, in Beth Israel Hospital, aged 74, from heart failure. His funeral mass was held at St. Patrick's Cathedral on November 27, and he was interred at Arlington National Cemetery, Section 2, Grave 889-A-RH.
