Reinfeld was born in Lubaczów, Poland (Then the Austrian partition [[]]) and emigrated to the United States in 1910, settling in Newark, New Jersey, where he opened a tavern.
Reinfeld formed a syndicate with Newark mobsters Abner Zwillman and Joseph Stacher, and henchman James Rutkin.
Testimony during the Kefauver Committee hearings estimated that Reinfeld's syndicate imported nearly 40% of all the alcohol consumed in the U.S. during Prohibition.
[5] After Prohibition ended in 1933, Reinfeld founded Browne-Vintners, a liquor import and distribution company, as a legal continuation of his old syndicate.
[6][7] Rutkin also filed a $22 million civil suit in 1948 against Reinfeld and Samuel Bronfman, alleging that he was defrauded out of his share of a distillery in Canada.
[10] The Reinfeld name is carried on today as a sub-division of New Jersey's largest wine & spirits distributor, Allied Beverage Group.
