  1. Percy LeBaron Spencer invented Microwave Oven

    As per Wikipedia “Spencer 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 accordingly began learning as much as possible about the phenomenon. Therefore, 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 formal training in electrical engineering or even finishing grammar school. At the age of 18, Spencer decided to join the U.S. Navy. He had become interested in wireless communications after learning about the wireless operators aboard the Titanic when it sank. While he was with the navy, he made himself an expert on radio technology: “I just got hold of a lot of textbooks and taught myself while I was standing watch at night.” He also subsequently taught himself trigonometry, calculus, chemistry, physics, and metallurgy, among other subjects.”
