Granville T. Woods, a self-taught engineer, invented the system that allowed trains to communicate while moving — the same technology that paved the way for modern subways and signal networks today. 🔌✨
Born in 1856, he left school at 10 and taught himself electrical engineering while working as a machinist and railroad fireman. By 30, he was designing the systems that powered America’s railroads and cities. ⚙️
With over 50 patents to his name, Woods proved that innovation knows no limits — only determination. 💪🏽
