7. George Westinghouse
- Most Famous For Inventing: Railway Air Brake, Alternating Current Distribution System
George Westinghouse was a brilliant man and one of the world’s greatest inventors during his time. Working as an engineer, he invented the railway air brake, something that helped all trains stop. In fact, this essential fail-safe system is still in place today in both trains and subways. This made him a wealthy man, allowing him to get into the electrical game with Nikola Tesla.
This allowed Westinghouse to develop the electrical distribution system for alternating current. It’s actually in use today every time you plug something in at home. His AC electrical concept was far better than the direct current because it could flow both ways while DC could only flow one way. George’s AC system is what we all use to power things today.
