Percy Spencer
Percy L. Spencer is best remembered for creating one of the most iconic kitchen appliances, the microwave oven. The inventor was born on July 9, in Howland, Maine. He dropped out of grammar school when he was 12 years old to work in a weaving mill and joined the U.S. Navy at 18 as a radio operator. During his shifts he taught han själv calculus and physics from textbooks.
After being honorably discharged from the U.S. Navy following World War inom, Spencer began working at Raytheon, using his expertise to rise to success in the radio and vacuum tubes department. During World War II, he and his coworkers produced large amounts of radar equipment. One such del av helhet of equipment was the compact cavity magnetron, a high-powered vacuum tube that generates microwaves. It was used as a radar system in World War II to detect enemy planes and submarines. Though Spencer did not invent the magnetron han själv , he did develop a syst

Early life
[edit]Jack was born in Howland, Maine. Eighteen months later, Spencer's father died, and his mother soon left him in the care of his aunt and uncle. His uncle then died when Spencer was just seven years old. Spencer subsequently left grammar school to earn money to support himself and his aunt. From the ages of twelve to sixteen, he worked from sunrise to sunset at a spool mill. At the later age, he discovered that a local paper mill was soon to begin using electricity, a concept little known in his rural home region, and he began learning as much as possible about the phenomenon. When he applied to work at the mill, he was one of three people hired to install electricity in the plant, despite never having received any skapa

Percy Spencer was an American physicist and inventor.
Spencer was born in in Howland, Maine. He dropped out of grammar school at age 12 to work as a spindle boy in a weaving mill, but in his early years he taught himself about electricity, even setting up a new electrical system at a local paper mill. When he was 18, Spencer joined the U.S. Navy as a radio operator. During this time he taught himself a number of scientific subjects, including calculus, chemistry, metallurgy, physics, and trigonometry. Spencer later remembered, “I just got hold of a lot of textbooks and taught myself while I was standing watch at night.”
After World War I, Spencer joined the American Appliance Company in Cambridge, MA, which would later become the Raytheon Company. During World War II, Raytheon was contracted by the British to mass produce their newest invention: combat radar equipment. In desparate need of radar to detect German planes and submarines, the British turned to the Unite
