THE PICTURE MAN OF 1890 - 1960
The History of Motion Pictures
The Warner Brothers open their own film exchange called the "Duquesne Amusement Supply Company" in a suburb of Pittsburgh.
Harry Warner, who operated a circuit of nickelodeons with his brothers in western Pennsylvania, began to buy films for his Pittsburgh-based Duquesne Amusement Supply Company in April 1907.
With his three brothers, Jack Warner (1892-1978) founded Warner Brothers movie studio, one of Hollywood's premiere forces during the studio era.Warner was also an influential movie producer, responsible for 5,000 films over the course of his career.
Born on August 2, 1892, in London, Ontario, Canada, Warner was the ninth of twelve children born to Benjamin and Pearl Leah Eichelbaum, and the youngest son of the seven children to survive into adulthood. Warner's parents were Jewish immigrants from Poland. Warner's father worked as a butcher, cobbler, and peddler to support his family. When Warner was two years old, the family moved to Youngstown, Ohio. In 1907, the family name was changed to "Warner." Jack Warner only had a fourth grade education and was a poor student while in school. This left him with life-long feelings of inferiority. His son Jack Warner, Jr., later told Jean Stein of The New Yorker, "I always felt, what the hell, he's a cum laude in his field, he doesn't have to feel negative about it. But he did have a great inferiority complex."
As a child, Warner wanted to be an entertainer, singing and telling jokes. When he was a teenager, he performed in vaudeville and at a local opera house under the name Leon Zuardo. Over his lifetime, he developed a reputation for telling bad jokes. Warner's niece, Betty Warner Sheinbaum, told Jean Stein of The New Yorker that "He was cute and funny and he wanted to be in show business; he was a pest from the day he was born."
Warner's elder brothers, including the eldest Harry as well as Sam and Albert, entered the movie exhibition business while Warner was a teenager. In 1906, these four Warner brothers and their sister Rose, moved to New Castle, Pennsylvania where they ran a movie theater. Jack continued to exercise his desire to entertain by singing between movies as a "chaser" to rid the theater of its audience between films. In 1907, the Warner clan moved into distribution with its Duquesne Amusement Supply Company, which rented films to theaters. They were forced to sell the business in 1910 because Thomas Edison, the inventor of many technical aspects of film production, held many patents through which he tried to control the burgeoning film industry. The Warners temporarily turned to movie making. Warner and his brother Sam went to St. Louis to make a film, The Perils of the Plains which was of poor quality and did not do well at the box office. After Edison's trust was legally broken, the Warners returned to distribution temporarily and then, in 1912, tried to get production started again. Warner represented the family's interests in San Francisco at the time.
First Warner Studio
World War I broke out and Warner and his brother Sam served in the Air Corps. During this time, Warner appeared in his only lead role in a military training film on the dangers of sexually transmitted diseases. By 1917, their efforts were concentrated on production, away from distribution. Warner moved to Los Angeles to start up a studio and worked as head of production for the new studio. The Warners' first hit was 1918's My Four Years in Germany. In 1920, Warner produced a 15-episode serial. Between 1920 and 1922, Warner produced about six feature-length films.
Warner Bros. Studio is Born
In 1922, the Warners moved into a bigger studio, and the company officially became known as Warner Bros. with Warner serving as head of production. The studio's earliest star was a dog named Rin Tin Tin. Warner Bros. slowly built up their stock of actors and the number of features the company released each year. By 1925, Warner was at the head of 30 features. Warner's importance in the studio grew throughout the 1920s as his responsibilities increased and he was making day-to-day decisions about who would work on what pictures. The studio however was not making much of a profit, though they had the theaters to show their pictures. In fact, Warner Bros. was deeply in the red.
Gambled on Sound
To salvage the company, Warner Bros. became the first studio to take a chance on a new technology: sound. This was a risky proposition in 1925, when they first announced their intentions. First, Warner Bros. tried Vitaphone, which allowed for a synchronized soundtrack and special effects, but no dialogue. In 1926, the company released Don Juan in this format, but it did not do well. Audiences were already used to orchestras accompanying silent films. In 1927, the Warners made a bigger gamble by putting out The Jazz Singer, the first movie to feature sound which included dialogue. The Jazz Singer was the most expensive movie Warner Bros. made up until that time, but the risk paid off because their innovation changed the industry. Warner Bros. became a major studio, and had a huge jump on their competition. Unfortunately for the family, Sam Warner died the night before the premiere. Sam was Warner's favorite brother, the buffer between Jack and his eldest brother, Harry.
With the success of The Jazz Singer, Warner Bros. was able to acquire a better studio and bigger stars. In the 1930s, Warner oversaw plant operations and the studio. As the Warner representative on the lot, he was officially the vice president and chief of production. He made most of the artistic and financial decisions, and was highly concerned with keeping the movies under budget. One way he accomplished this was by focusing on one star (usually male) in each picture. Richard Schikel of Fortune wrote, "Efficiency was an obsession with crude, shrewd Jack Warner, who supervised production while his brother attended to more boring matters, like distribution and finance. Jack was known to prowl the lot looking for lights that had been left on unnecessarily."..
Early Warner Brothers History:
The Warner brothers (Harry, Albert, Sam, and Jack), originally soap salesmen in Youngstown, Ohio, visited nearby Pittsburgh, PA and realized the potential of nickelodeons. In 1904 (some sources claimed 1907), they founded the Pittsburgh-based Duquesne Amusement Supply Company - reportedly the first film exchange (or distribution company) in the US. They bought a used Edison Kinetoscope projector, and toured through W. Pennsylvania and Ohio to exhibit films (mostly The Great Train Robbery (1903)). They also opened their first silent film theatre, the 99-seat Cascade Theatre, in the mining town of New Castle, Pennsylvania in 1907, which they operated until 1911. In 1912, Sam Warner opened a film production office in Los Angeles, Warner Bros. Pictures, and formally incorporated in 1923.
In 1907, Warner expanded the business further and purchased fifteen theaters in Pennsylvania. As a result of these purchases, Harry, Sam, and Albert would form a new film exchange company, The Duquesne Amusement Supply Company, and rented an office in the Bakewell building in downtown Pittsburgh. Harry then sent Sam to New York to purchase, and ship, films for their Pittsburgh exchange company, while he and Albert remained in Pittsburgh to run the business. In 1909, the brothers were able to successfully sell the Cascade Theater and establish a second film exchange company in Norfolk, Virginia. Through this second exchange company in Norfolk, Harry agreed to let younger brother Jack be apart of the company, and sent him to Norfolk to serve as Sam's assistant.A serious problem threatened the Warners' film company with the advent of...
