Ohio derives its name from the Ohio River that forms its southern border, which, in turn, originated from the Seneca word ohiːyo', meaning "good river", "great river", or "large creek". The state was home to several ancient indigenous civilizations, with humans being present as early as 10,000 BCE. It arose from the lands west of the Appalachian Mountains that were contested by various native tribes and European colonists from the 17th century through the Northwest Indian Wars of the late 18th century. Ohio was partitioned from the Northwest Territory, which was the first frontier of the new United States, becoming the 17th state admitted to the Union on March 1, 1803, and the first under the Northwest Ordinance. Ohio was the first post-colonial free state admitted to the union and became one of the earliest and most influential industrial powerhouses during the 20th century. Although it has transitioned to a more information- and service-based economy in the 21st century, it remains an industrial state, ranking seventh in GDP , with the third-largest manufacturing sector and second-largest automobile production.
The Dayton Project began in 1943 when Monsanto's Charles Allen Thomas was recruited by the Manhattan Project to coordinate the plutonium purification and production work being carried out at various sites. Scientists at the Los Alamos Laboratory calculated that a plutonium bomb would require a neutron initiator. The best-known neutron sources used radioactive polonium and beryllium, so Thomas undertook to produce polonium at Monsanto's laboratories in Dayton. While most Manhattan Project activity took place at remote locations, the Dayton Project was located in a populated, urban area. It ran from 1943 to 1949, when the Mound Laboratories were completed in nearby Miamisburg, Ohio, and the work moved there.
Jack Leonard Warner (born Jacob Warner; August 2, 1892 – September 9, 1978) was a Canadian-American film executive, who was the president and driving force behind the Warner Bros. Studios in Burbank, California. Warner's career spanned some fifty-five years, its duration surpassing that of any other of the seminal Hollywood studio moguls.
As co-head of production at Warner Bros. Studios, Warner worked with his brother, Sam Warner, to procure the technology for the film industry's first talking picture, The Jazz Singer (1927). After Sam's death, Jack clashed with his surviving older brothers, Harry and Albert Warner. He assumed exclusive control of the company in the 1950s when he secretly purchased his brothers's shares in the business after convincing them to participate in a joint sale of stocks.
