Jack Cohn

From Grokipedia

Jack Cohn (October 27, 1889 – December 8, 1956) was an American film producer and executive best known as a co-founder of Columbia Pictures Corporation alongside his brother Harry Cohn and business partner Joe Brandt. Born Jacob Cohn in New York City to Jewish immigrant parents Joseph and Bella Cohn, he rose from humble beginnings in the early film industry to become a pivotal figure in Hollywood's growth, serving as vice president and treasurer of the studio he helped build into a major motion picture powerhouse.

Cohn's career began in 1908 when, at age 19, he joined Carl Laemmle's Independent Motion Picture Company (IMP) as a laboratory assistant earning $7 per week, quickly advancing to roles in editing and production. He contributed to early successes such as the 1913 film Traffic in Souls, which he edited and which grossed $450,000 on a budget of approximately $5,000, pioneering spot news bureaus and short-subject departments at Universal Studios, IMP's successor. By 1918, Cohn, his brother Harry, and Joe Brandt established the Cohn-Brandt-Cohn (CBC) Film Sales Corporation with modest capital of $250, initially focusing on distributing short films before expanding into feature production.

In 1924, the company was renamed Columbia Pictures Corporation, with Jack Cohn overseeing the New York-based home office and sales operations while Harry managed production in Hollywood; under their leadership, Columbia grew to encompass 33 domestic offices, over 100 international branches, assets exceeding $65 million, and annual sales of $90 million by the mid-1950s. Despite a tumultuous relationship marked by a 1932 shareholders' revolt led by Jack against Harry's production control—though Harry retained power—the brothers' partnership endured, transforming Columbia from a "poverty row" distributor into a studio renowned for films like Frank Capra's It Happened One Night (1934). Cohn also co-founded the Motion Picture Pioneers in 1939, supporting industry veterans through its charitable foundation, and left a legacy through his sons Ralph (general manager of Screen Gems) and Robert (Columbia executive in Paris). He died of pulmonary embolism in New York City at age 67, survived by his wife Jeanette Lesser Cohn and family.

In brief

Jack Cohn worked the business side of a brother act that became a studio. If Harry was the storm on the lot, Jack was the man who kept the company a company.

Columbia’s rise is usually told as one Cohn. It was two. Founding is a plural verb when the letterhead has a family name on it.
