The wizard of Menlo Park, whose ideas helped shape the modern world

💡 1. The Practical Incandescent Light Bulb (1879)

Arguably Edison’s most famous invention, the incandescent light bulb brought safe, durable artificial light to homes and businesses. Though others experimented with electric lighting before him, Edison’s version was the first that could be mass-produced and used in everyday life — a real game-changer for work, school, and life after dark.

📀 2. The Phonograph (1877)

Long before iPods and digital files, Edison invented the phonograph — the first machine that could record and play back sound. People were astonished that voices and music could be saved and replayed, and this device laid the groundwork for the entire recorded music industry. Edison himself called this his favorite invention.

📞 3. The Carbon Telephone Transmitter (1877–78)

Edison didn’t invent the telephone, but he perfected it. His carbon button transmitter vastly improved sound quality, enabling clearer, more practical long-distance telephone communication that kept conversations understandable and reliable.

🖨️ 4. The Electric Pen & Mimeograph (1875–76)

This early office machine used electricity to duplicate documents, a forerunner of the modern copier. While today’s offices use laser and inkjet machines, Edison’s electric pen helped businesses reduce the tedium of handwritten copies.

📽️ 5. Motion Picture Camera & Viewer (Late 1880s–1890s)

Edison’s team created the Kinetograph (a motion picture camera) and the Kinetoscope (a peephole movie viewer), early tools that ignited the motion picture industry. These inventions helped take storytelling off the still photo and onto the moving screen.

⚡ 6. The Pearl Street Power Station & Electric Power System (1882)

Edison didn’t just invent bulbs — he invented a system to power them. His Pearl Street Station in New York was one of the first commercial power plants, providing electricity to businesses and homes and launching the electric utility business.

🔋 7. Nickel-Iron (Alkaline) Battery (1900)

To power machines or early electric cars of his day, Edison developed a more durable rechargeable battery made from nickel and iron. While not as common now, it was a major step in battery technology.

🌡️ 8. The Tasimeter & Phonomotor (Late 1870s)

Beyond big household names, Edison also created scientific curiosities:

Tasimeter — a device to measure tiny temperature changes, especially useful in solar observations.
Phonomotor — a gadget that converted sound into motion, essentially turning voice power into mechanical energy.
