David Sarnoff was born to a Jewish family in Uzlyany, a small town in the Russian Empire, now part of Belarus, the son of Abraham and Leah Sarnoff. Abraham emigrated to the United States and raised funds to bring the family. Sarnoff spent much of his early childhood in a cheder (or yeshiva) studying and memorizing the Torah. He emigrated with his mother and three brothers and one sister to New York City in 1900, where he helped support his family by selling newspapers before and after his classes at the Educational Alliance. In 1906 his father became incapacitated by tuberculosis, and at age 15 Sarnoff went to work to support the family. He had planned to pursue a full-time career in the newspaper business, but a chance encounter led to a position as an office boy at the Commercial Cable Company. When his superior refused him paid leave for Rosh Hashanah, he joined the Marconi Wireless Telegraph Company of America on September 30, 1906, and started a career of over 60 years in electronic communications.

Over the next 13 years, Sarnoff rose from office boy to commercial manager of the company, learning about the technology and the business of electronic communications on the job and in libraries. He also served at Marconi stations on ships and posts on Siasconset, Nantucket and the New York Wanamaker Department Store. In 1911, he installed and operated the wireless equipment on a ship hunting seals off Newfoundland and Labrador, and used the technology to relay the first remote medical diagnosis from the ship’s doctor to a radio operator at Belle Isle with an infected tooth.

This demonstration and the AT&T demonstrations in 1915 of long-distance wireless telephony inspired the first of many memos to his superiors on applications of current and future radio technologies. Sometime late in 1915 or in 1916 he proposed to the company’s president, Edward J. Nally, that the company develop a “radio music box” for the “amateur” market of radio enthusiasts. Nally deferred on the proposal because of the expanded volume of business during World War I. Throughout the war years, Sarnoff remained Marconi’s Commercial Manager, including oversight of the company’s factory in Roselle Park, New Jersey.

On July 4, 1917, Sarnoff married Lizette Hermant, the daughter of a French-Jewish immigrant family who settled in the Bronx as one of his family’s neighbors. The Museum of Broadcast Communications describes their 54-year marriage as the bedrock of his life. Lizette was often the first person to hear her husband’s new ideas as radio and television became integral to American home life.

When Owen D. Young of General Electric arranged the purchase of American Marconi and turned it into the Radio Corporation of America, a radio patent monopoly, Sarnoff realized his dream and revived his proposal in a lengthy memo on the company’s business and prospects. His superiors again ignored him but he contributed to the rising postwar radio boom by helping arrange for the broadcast of a heavyweight boxing match between Jack Dempsey and Georges Carpentier in July 1921. Up to 300,000 people heard the fight, and demand for home radio equipment bloomed that winter. By the spring of 1922 Sarnoff’s prediction of popular demand for broadcasting had come true, and over the next eighteen months, he gained in stature and influence.

In 1925, RCA purchased its first radio station (WEAF, New York) and launched the National Broadcasting Company (NBC), the first radio network in America. Four years later, Sarnoff became president of RCA. NBC had by that time split into two networks, the Red and the Blue. The Blue Network later became ABC Radio. Sarnoff was often inaccurately referred to later in his career as the founder of both RCA and NBC, but he was in fact founder of only NBC.

When Sarnoff was put in charge of radio broadcasting at RCA, he soon recognized the potential for television, i.e., the combination of motion pictures with electronic transmission. Schemes for television had long been proposed (well before World War I) but with no practical outcome. Sarnoff was determined to lead his company in pioneering the medium and met with Westinghouse engineer Vladimir Zworykin in 1928. At the time Zworykin was attempting to develop an all-electronic television system at Westinghouse, but with little success. Zworykin had visited the laboratory of the inventor Philo T. Farnsworth, who had developed an Image Dissector, part of a system that could enable a working television. Zworykin was sufficiently impressed with Farnsworth’s invention that he had his team at Westinghouse make several copies of the device for experimentation.

In 1929, Sarnoff engineered the purchase of the Victor Talking Machine Company, the nation’s largest manufacturer of records and phonographs, merging radio-phonograph production at Victor’s large manufacturing facility in Camden, New Jersey.

The final cost of the enterprise was closer to $50 million. On the road to success they encountered a legal battle with Farnsworth, who had been granted patents in 1930 for his solution to broadcasting moving pictures. Despite Sarnoff’s efforts to prove that he was the inventor of the television, he was ordered to pay Farnsworth $1,000,000 in royalties, a small price to settle the dispute for an invention that would profoundly revolutionize the world.

Sarnoff became president of RCA on January 3, 1930, succeeding General James Harbord. On May 30 the company was involved in an antitrust case concerning the original radio patent pool. Sarnoff negotiated an outcome where RCA was no longer partly owned by Westinghouse and General Electric, giving him final say in the company’s affairs.

Zworykin pitched the concept to Sarnoff, claiming a viable television system could be realized in two years with a mere $100,000 investment. Sarnoff opted to fund Zworkyin’s research, most likely well-aware that Zworykin was underestimating the scope of his television effort. Seven years later, in late 1935, Zworykin’s photograph appeared on the cover of the trade journal Electronics, holding an early RCA photomultiplier prototype. The photomultiplier, subject of intensive research at RCA and in Leningrad, Russia, would become an essential component within sensitive television cameras. On April 24, 1936, RCA demonstrated to the press a working iconoscope camera tube and kinescope receiver display tube (an early cathode ray tube), two key components of all-electronic television.

Initially, the Great Depression caused RCA to cut costs, but Zworykin’s project was protected. After nine years of Zworykin’s hard work, Sarnoff’s determination, and legal battles with Farnsworth (in which Farnsworth was proved in the right), they had a commercial system ready to launch. Finally, in April 1939, regularly scheduled, electronic television in America was initiated by RCA under the name of their broadcasting division at the time, The National Broadcasting Company (NBC). The first television broadcast aired was the dedication of the RCA pavilion at the 1939 New York World’s Fairgrounds and was introduced by Sarnoff himself. Later that month on April 30, opening day ceremonies at The World’s Fair were telecast in the medium’s first major production, featuring a speech by President Franklin D. Roosevelt, the first US President to appear on television. These telecasts were seen only in New York City and the immediate vicinity, since NBC television had only one station at the time, W2XBS Channel 1, now WNBC Channel 4. The broadcast was seen by an estimated 1,000 viewers from the roughly 200 televisions sets which existed in the New York City area at the time.

The standard approved by the National Television System Committee (the NTSC) in 1941 differed from RCA’s standard, but RCA quickly became the market leader of manufactured sets and NBC became the first television network in the United States, connecting their New York City station to stations in Philadelphia and Schenectady for occasional programs in the early 1940s.

Sarnoff anticipated that post-war America would need an international radio voice explaining its policies and positions. In 1943, he tried to influence Secretary of State Cordell Hull to include radio broadcasting in post-war planning. In 1947, he lobbied Secretary of State George Marshall to expand the roles of Radio Free Europe and Voice of America. His concerns and proposed solutions were eventually seen as prescient.

At the onset of World War II, Sarnoff served on Eisenhower’s communications staff, arranging expanded radio circuits for NBC to transmit news from the invasion of France in June 1944. In France, Sarnoff arranged for the restoration of the Radio France station in Paris that the Germans destroyed and oversaw the construction of a radio transmitter powerful enough to reach all of the allied forces in Europe, called Radio Free Europe. In recognition of his achievements, Sarnoff was decorated with the Legion of Merit on October 11, 1944.

Thanks to his communications skills and support he received the Brigadier General’s star in December 1945, and thereafter was known as “General Sarnoff.” The star, which he proudly and frequently wore, was buried with him.

After the war, monochrome TV production began in earnest. Color TV was the next major development, and NBC once again won the battle. CBS had their electro-mechanical color television system approved by the FCC on October 10, 1950, but Sarnoff filed an unsuccessful suit in the United States district court to suspend that ruling. Subsequently, he made an appeal to the Supreme Court which eventually upheld the FCC decision. Sarnoff’s tenacity and determination to win the “Color War” pushed his engineers to perfect an all-electronic color television system that used a signal that could be received on existing monochrome sets that prevailed. CBS was now unable to take advantage of the color market, due to lack of manufacturing capability and color programming, a system that could not be seen on the millions of black and white receivers and sets that were triple the cost of monochrome sets. A few days after CBS had its color premiere on June 14, 1951, RCA demonstrated a fully functional all-electronic color TV system and became the leading manufacturer of color TV sets in the US.

CBS system color TV production was suspended in October 1951 for the duration of the Korean War. As more people bought monochrome sets, it was increasingly unlikely that CBS could achieve any success with its incompatible system. Few receivers were sold, and there were almost no color broadcasts, especially in prime time, when CBS could not run the risk of broadcasting a program which few could see. The NTSC was reformed and recommended a system virtually identical to RCA’s in August 1952. On December 17, 1953 the FCC approved RCA’s system as the new standard.

In 1955, Sarnoff received The Hundred Year Association of New York’s Gold Medal Award “in recognition of outstanding contributions to the City of New York.”

In 1959 Sarnoff was a member of the Rockefeller Brothers Fund panel to report on U.S. foreign policy. As a member of that panel and in a subsequent essay published in Life as part of its “The National Purpose” series, he was critical of the tentative stand being taken by the United States in fighting the political and psychological warfare being waged by Soviet-led international Communism against the West. He strongly advocated an aggressive, multi-faceted fight in the ideological and political realms with a determination to decisively win the Cold War.

Sarnoff retired in 1970, at the age of 79, and died the following year, aged 80. He is interred in a mausoleum featuring a stained-glass vacuum tube in Kensico Cemetery in Valhalla, New York.

The couple had three sons. Eldest son Robert W. Sarnoff (1918-1997) succeeded his father at the helm of RCA in 1970. Robert’s second wife was operatic soprano Anna Moffo. Edward Sarnoff, the middle child, headed Fleet Services of New York. Thomas W. Sarnoff, the youngest, was NBC’s West Coast President.
