"Thomas Edisons Patent Application for the Light Bulb (1880)
Thomas Edison propelled the United States out of the gaslight era and into the electric age. From the time he was a boy, he was mesmerized by the mechanics of the universe and, with virtually no formal education, brought forth innovations that continue to dominate our lives. Out of his New Jersey laboratories, which were themselves inventions—thoroughly equipped and fully staffed—came 1,093 patented inventions and innovations that made Edison one of the most prolific inventors of all time.

Three of his most famous inventions, the phonograph, a practical incandescent light bulb, and the moving picture camera, dazzled the public and revolutionized the way people live throughout the world. His thundering dynamos transformed the United States into the world’s greatest industrial superpower.

In 1878 the creation of a practical long-burning electric light had eluded scientists for decades. With dreams of lighting up entire cites, Edison lined up financial backing, assembled a group of brilliant scientists and technicians, and applied his genius to the challenge of creating an effective and affordable electric lamp. With unflagging determination, Edison and his team tried out thousands of theories, convinced that every failure brought them one step closer to success. On January 27, 1880, Edison received the historic patent embodying the principles of his incandescent lamp that paved the way for the universal domestic use of electric light."
