Figure timeline
Percy LaBaron Spencer was an American physicist, electrical engineer, and inventor of the microwave oven. As a boy he was twice orphaned and began work at a young age, never finishing grammar school. During the night shift, he taught himself topics such as calculus, trigonometry, physics, and chemistry, establishing a lifelong habit of self-education or "solving my own situation" as he called it.
