Maxim's influence is with us to this day.
We all use electric light bulbs.
Many of our buildings have his automatic fire extinguishers.
All of our aircraft use control systems pioneered by him.
He also started two companies which continue in business. One was the Maxim Machine Gun Company, which became Maxim-Nordenfeldt, which became Vickers, Sons & Maxim, which became Vickers Ltd and now is Vickers-Sperry.
The other was the Maxim Electric Lighting Company, which became Maxim-Weston and now is called General Electric.
Busy boy, you might say.
