Lubinsky was born to a Jewish family[3] in Branford, Connecticut,[4][nb 1] the son of Fannie (née Rosinsky; 1865–1941) and Louis Lubinsky (also known as Leuvinsky; 1857–1921), both of whom had emigrated from Russia in 1883.[5]
By 1915, he was working as an electrical contractor in New Haven,[6] before serving as a radio operator in the US Navy.[7] In 1922, Lubinsky founded The Radio Shop of Newark, in Newark, New Jersey,[8] and, in 1923, set up a radio station, WRAZ, which changed its title to WCBX and then, in October 1924, to WNJ.
The station operated from the attic of Lubinsky's home before its studio in Newark opened in 1925. The station became known as "The Voice of Newark" and presented programmes for immigrants to the New York metropolitan area in Polish, Lithuanian and Italian.[7]
In 1929, Lubinsky set up the Radio Investment Co., but in November 1932 his application to renew the license for WNJ was refused by the Federal Radio Commission because he refused to accept limits on the station's bandwidth.[9] Lubinsky fought the action in the courts, but the station was taken off the air in March 1933.[7]
Lubinsky has been described as "an arrogant bully... the quintessential loudmouth, overweight, cigar-smoking record man with little apparent charm";[9] as "a colorful character... endowed with a shrewd business sense";[15] and as "a rather profane cheapskate who had a low opinion of many of the musicians that he recorded" and who "was best known for his desire to cut expenses at all costs".[16] His oldest daughter, Lois Grossberg, later said, "He was paranoid about money. It consumed him like a burning fire. He had a reputation as an ogre in the business. You have no idea of the cheapness."[15]
The singer Little Jimmy Scott recorded for Savoy in the 1950s. He left the label in the early 1960s and recorded an album with Ray Charles for the latter's new label, Tangerine. However, Lubinsky claimed that Scott was under contract to him for his lifetime. The record was withdrawn. As a result, Scott retreated from the recording industry until after Lubinsky's death.[17]
