One of the most creative technical innovators in the world Thomas Alva Edison (February 11, 1847 – October 18, 1931) ushered in the electric age and holds 1093 patents for groundbreaking inventions like the light bulb and phonograph.
Upset by his kindergarten teacher dismissing him as addle brained due to his incessant questions and large head, his mother decided to home school him. With no formal education, his knowledge was gained through his constant experimenting and copious reading. Starting his career as a young crackerjack (expert) telegraph operator, he grew into a savvy and shrewd businessman with a talent for transferring technology from lab to market; making his inventions affordable, he promoted them to ensure success, building the first industrial research laboratory.
Edison did not invent the light bulb from scratch. He improved upon a 50-year-old idea, making it practical for the common man. After one and a half years of tireless work, he developed an incandescent lamp with a filament of carbonized sewing thread that burned for thirteen and a half hours in 1879. For a practical, safe, and economical electric lighting system Edison invented the parallel circuit, a durable light bulb, an improved dynamo, the underground conductor network, the devices for maintaining constant voltage, safety fuses and insulating materials, and light sockets with on-off switches. The first public demonstration of his incandescent lighting system took the world by storm at Edison’s Menlo Park laboratory complex.
