Splitdorf-Bethlehem Electrical Co. signed by Charles Edison - 1929 dated Stock Certificate (Uncanceled)

Uncanceled stock signed by Charles Edison and H. F. Miller who was Edison's private secretary. Edison merged 40 companies into the Thomas A. Edison, Inc. Franklin Lee Division of American Bank Note.

Thomas A. Edison, Incorporated (originally the National Phonograph Company) was the primary holding company for the different manufacturing companies established by the inventor and entrepreneur Thomas Edison. It succeeded the Edison Manufacturing Company and operated between 1911 and 1957. In 1957, it merged with McGraw Electric to form McGraw-Edison.

In the 1920s, the recording company struggled to keep pace with technological advancements and attract recording stars comparable to those of its competitors, Victor and Columbia. An attempt to launch a long-playing record in 1926 was unsuccessful, and the company did not adopt condenser microphones for electrical recording until mid-1927, two years after the industry had widely embraced the technology. In 1928, the company expanded into the radio market by acquiring Splitdorf Radio Corp.

On November 1, 1929, Edison halted record production, continuing only with dictation records through its Voicewriter division. Additionally, in the late 1920s, the company developed the "Edicraft" line of high-quality consumer appliances at its laboratory, which was manufactured by Thomas A. Edison, Inc. However, due to the decreased demand for luxury goods during the Great Depression, production of these appliances ceased in 1934.

Charles Edison (August 3, 1890 – July 31, 1969) was an American politician, businessman, inventor and animal behaviorist. He was the Assistant and then United States Secretary of the Navy, and served as the 42nd Governor of New Jersey. Commonly known as "Lord Edison", he was a son of Thomas Edison and Mina Miller Edison.

Born at his parents' home, Glenmont, in West Orange, New Jersey, he graduated from the Hotchkiss School in Lakeville, Connecticut, in 1909. In 1915–1916, he operated the 100-seat "Little Thimble Theater" with Guido Bruno. There they played the works of George Bernard Shaw and August Strindberg while Charles contributed verse to Bruno's Weekly under the pseudonym "Tom Sleeper". Late in 1915, he brought his players to Ellis Island to perform for Chief Clerk Augustus Sherman and more than four hundred detained immigrants. These avant-garde activities came to a halt when his father put him to work. He married Carolyn Hawkins on March 27, 1918. They had no children. For a number of years Charles Edison ran Edison Records. Charles became president of his father's company Thomas A. Edison, Inc. in 1927, and ran it until it was sold in 1957, when it merged with the McGraw Electric Company to form the McGraw-Edison Electric Company. Edison was board chairman of the merged company until he retired in 1961.

On January 18, 1937, President Roosevelt appointed Charles Edison as Assistant Secretary of the Navy, then as Secretary on January 2, 1940, Claude A. Swanson having died several months previously. Edison himself only kept the job until June 24, resigning to run his gubernatorial campaign. During his time in the Navy department, he advocated construction of the large Iowa-class battleships, and that one of them be built at the Philadelphia Navy Yard, which secured votes for Roosevelt in Pennsylvania and New Jersey in the 1940 presidential election; in return, Roosevelt had BB-62 named the USS New Jersey.

In 1940, he won election as Governor of New Jersey, running in reaction to the political machine run by Frank Hague, but broke with family tradition by declaring himself a Democrat. As governor, he proposed updating the New Jersey State Constitution. Although it failed in a referendum and nothing was changed during his tenure, state legislators did reform the constitution later. In 1948, he established a charitable foundation, originally called "The Brook Foundation", now the Charles Edison Fund.

Between 1951 and 1969, he lived in the Waldorf-Astoria Hotel, where he struck up a friendship with Herbert Hoover, who also lived there. In 1962, Edison was one of the founders of the Conservative Party of New York State.

In 1967, Edison hosted a meeting at the Waldorf-Astoria in New York that led to the founding of the Charles Edison Youth Fund, later the Charles Edison Memorial Youth Fund. Attending the meeting were Rep. Walter Judd (R-MN), author William F. Buckley, organizer David R. Jones, and Edison's political advisor Marvin Liebman. The name of the organization was changed in 1985 to The Fund for American Studies, in keeping with Edison's request to drop his name after 20 years of use.

In 1924, Edison joined the New Jersey Society of the Sons of the American Revolution. He was assigned national member number 39,292 and state society number 2,894.

Charles Edison died on July 31, 1969, in New York City, three days shy of his 79th birthday. He is buried in Rosedale Cemetery in Orange, New Jersey.
