📡 Guglielmo Marconi (1874–1937)

Guglielmo Marconi was an Italian inventor and electrical engineer who is widely known as the “Father of Radio.” Born in Bologna, Italy, Marconi was fascinated by the ideas of electromagnetic waves and started experimenting with wireless telegraphy at a young age. In 1896, he successfully sent and received wireless signals and applied for the world’s first patent in wireless communication. His experiments soon achieved long-distance transmissions, including sending signals across the Atlantic Ocean in 1901. Marconi’s inventions revolutionized global communication, making it possible for ships and distant places to exchange messages without cables. For his contributions, he received the Nobel Prize in Physics in 1909. However, later studies revealed that Indian scientist Jagadish Chandra Bose had conducted similar experiments even earlier. Still, Marconi’s name became famous worldwide because of his patents and commercial success. Despite the controversy, Marconi’s work remains vital in the history of modern communication.

2. Jagadish Chandra Bose (1858–1937) Jagadish Chandra Bose was a pioneering Indian scientist who first demonstrated the use of radio waves for wireless communication in 1895—two years before Marconi. Bose built his own instruments to transmit and receive signals and also made discoveries in plant physiology. Despite his groundbreaking work, he did not patent his inventions because he believed science should serve humanity. His humility and innovation make him one of India’s most inspiring scientists.

3. Guglielmo Marconi (1874–1937) Guglielmo Marconi was an Italian inventor credited with the development of practical wireless telegraphy. In 1896, he patented his version of wireless transmission and later received the Nobel Prize in Physics in 1909. Although his experiments came after Bose’s, Marconi’s focus on commercialization and global promotion brought him international fame as the ‘Father of Radio’. His work laid the foundation for modern wireless communication systems.
