Abraham E. Lefcourt (March 27, 1876 – November 13, 1932^[1]),^[2] better known as A.E. Lefcourt, was a prominent real estate developer in New York City in the 1920s. In his lifetime Lefcourt was known as one of the most prolific developers of Art Deco buildings in New York City.^[3] Describing Lefcourt in a 1930 newspaper article, The New York Times said, "No other individual or building organization has constructed in its own behalf as many buildings as are in the Lefcourt Group."^[4]

Lefcourt was born Abraham Elias Lefkowitz on March 27, 1876, to Russian-Jewish immigrants in Birmingham, England.^[5] His family immigrated to New York's Lower East Side in 1882 where Lefcourt grew up in a predominantly Jewish and poor community.

Lefcourt began his career as a newsboy and bootblack. He became a prominent figure in the New York garment industry when he assumed control of his employer's wholesale business. His forays into real-estate began in 1910 with a 12-story loft on West 25th Street. He built many more structures in the area, including the Alan E. Lefcourt building at 49th Street, known today as the Brill Building, heralding the beginnings of the new Garment Center.

An entrepreneur, Lefcourt had numerous other business interests, including founding Lefcourt Normandie National Bank, which eventually became a part of JP Morgan Chase.^[6][7]

Notwithstanding his success and a net worth reported to have been as much as $100 million in 1928,^[8] Lefcourt's empire began to unravel during the Depression, with his company going into foreclosure and his buildings being auctioned off.^[9] In 1932, with creditors pursuing him and others accusing him of fraud, Lefcourt suffered a heart attack in his Savoy-Plaza Hotel apartment and died at the age of 55.^[10]

He married Irma Viola Castleberg (1883–1949). The couple began using the surname Lefcourt around 1900 but did not officially adopt the name until 1909.^[11] The Lefcourts had two children: Mildred Audrey, born in 1908, and Alan Elias, born in 1913. Lefcourt constructed the Brill Building in part as a memorial to his son Alan Elias who died of anemia in February 1930.^[12] Lefcourt himself died on November 13, 1932, at the Savoy Hotel, leaving an estate of only $2,500.^[13] Services were held at Temple Emanu-El in Manhattan.^[14] Mrs. Lefcourt died in 1949 at Nantucket, MA; she was at the time of her death listed as a resident of the Savoy-Plaza Hotel.
