granvill t woods

 

Granville T. Woods (1856–1910) was a pioneering African American inventor and engineer, often called “The Black Edison” for his prolific contributions to electrical and mechanical engineering—especially in the railroad industry.

🛠️ Key Achievements

• Held over 60 patents, many related to railroads, telegraphs, and electrical systems.
• Invented the Synchronous Multiplex Railway Telegraph, which allowed communication between moving trains and stations using ambient static electricity from telegraph lines.
• Developed innovations like the automatic air brake, third rail system, and overhead conducting system for electric railways.
• Created devices like the telegraphony (a combination of telephone and telegraph), an egg incubator, and improvements to the phonograph.

📚 Early Life & Career

• Born in Columbus, Ohio, Woods left school at age 10 due to poverty and began working as a machinist and blacksmith.
• He gained practical experience in railroads and steamships, eventually becoming a chief engineer on a British steamer.
• Though largely self-taught, he studied engineering and electronics while working, and later founded the Woods Electric Co. in Cincinnati.

⚖️ Legacy & Recognition

• Woods often had to defend his patents in court due to racial discrimination. He famously won a legal battle against Thomas Edison over patent rights and declined Edison’s offer to collaborate, valuing his independence.
• His work laid the foundation for safer, more efficient urban transportation and communication systems.
