1. Early Experimentation:
-Heinrich Hertz (1886-1887): Conclusive evidence of electromagnetic waves that made radio possible.
2. Transmitting and Receiving Signals:
-Nikola Tesla (1893): Created a radio transmission and reception system, but it was not widely publicized or developed further.
3. The Race for Wireless Communication:
-Guglielmo Marconi (1894-1896): Conducted crucial experiments, transmitting and receiving radio waves over increasing distances.
4. Commercialization and Practical Applications:
-Oliver Lodge, Alexander Popov, and Reginald Fessenden (1895-1902): Made significant contributions to radio telegraphy and long-distance transmission.
5. Wireless Telegraphy and the Transatlantic Signal:
-Guglielmo Marconi (1899-1901): Successfully sent the first transatlantic wireless signal from England to Newfoundland.
6. Advances in Radio Technology:
-Lee de Forest (1906): Developed the Audion tube, a significant improvement in radio receivers.
It is important to note that many inventors, scientists, and engineers played crucial roles in the various aspects of radio development. The advancement of radio involved collaborations and incremental improvements, making it difficult to attribute the invention solely to one person.
