October 18, 1931 — West Orange, New Jersey
Mary Stilwell; Mina Miller
6 children
Patents, electrical companies, phonograph and motion-picture businesses, and later battery products; no single historical figure captures his full wealth.
Scientific and educational influence through laboratories, research teams, public demonstrations, and support for innovation; personal philanthropy is not the primary focus of this profile.
A LIFE IN FIVE TURNING POINTS
- 1847 — Born in Milan, Ohio.
- 1869 — Moves to New York and develops telegraph-related inventions.
- 1871 — Establishes a laboratory and manufacturing facility in Newark.
- 1876 — Opens the Menlo Park laboratory.
- 1877 — Demonstrates the phonograph.
- 1879–1882 — Develops a practical electric-lighting system; Pearl Street Station opens in 1882.
- 1887 — Opens a large laboratory complex in West Orange.
- 1890s — Develops motion-picture and phonograph businesses and experiments with iron-ore processing.
- 1899–1909 — Works on alkaline storage batteries.
- 1931 — Dies at Glenmont in West Orange.
HOW THE FORTUNE WORKED
Edison’s industrial research model brought inventors, machinists, chemists, and commercial manufacturing into one coordinated system. It helped translate experiments into products, while many technologies emerged from cumulative work by teams and earlier inventors.
WHAT CAN BE MEASURED
▤ DOCUMENTED RECORD
- National Park Service history documents Edison’s laboratories, phonograph, electric-lighting system, motion pictures, batteries, and business restructuring; the Library of Congress documents his life, papers, and communications history.
These records establish what can be known with reasonable confidence.
⚖ HISTORICAL ESTIMATES
- Claims that Edison “invented electricity” or single-handedly created every technology oversimplify a collaborative history. This profile describes documented systems and milestones rather than assigning all credit to one person.
ESTIMATES ARE NOT CERTAINTIES.
They inform perspective, not conclusions.
THE QUIET LESSON
Innovation is often a process: research, testing, financing, manufacturing, and adoption must work together. Public fame can obscure the contributions of collaborators and earlier inventors.
