Description: (Inventor, Engineer)
Alexander Nikolayevich Lodygin was a Russian electrical engineer and inventor known for his contributions to the development of the incandescent light bulb. Though his invention did not achieve commercial success initially, his design featuring a tungsten filament laid the foundation for modern light bulbs. Lodygin also introduced an early concept of a self-contained diving apparatus in 1871, resembling modern scuba gear, and his ideas for an electric helicopter later influenced Igor Sikorsky. His innovative work was acknowledged posthumously, leaving a lasting impact on technology across different domains.
