In the beginning — or at least from 1878 to 1880 — Thomas Edison labored to create better, more efficient light. At the time, incandescent lamps were too bright for small spaces. They use electricity to heat the filament, or a thin strip of metal, until it glows. Edison is said to have tested thousands of theories to develop an efficient incandescent lamp.
“The electric light has caused me the greatest amount of study and has required the most elaborate experiments,” Edison wrote. “I was never myself discouraged or inclined to be hopeless of success. I cannot say the same for all my associates.”
