Step-by-step explanation:
The creator of modern jazz organ is Jimmy Smith. Jimmy Smith revolutionized the use of the Hammond organ in jazz during the 1950s and is widely regarded as a pivotal figure in the instrument's history. Smith brought a new level of virtuosity to the instrument, building upon blues, gospel, and bop influences to create an organ sound that was completely unique and perfectly suited to the modern jazz of his time. His innovative work laid the foundation for future generations of jazz organists.
As for the question regarding the invention of the radio, the credit largely goes to Guglielmo Marconi. Marconi's work in the late 19th and early 20th centuries on the transmission of wireless signals was pivotal to the development of radio communication. His successful experiments in wireless telegraphy earned him the Nobel Prize in Physics in 1909 and solidified his place in history as a primary inventor of the radio.
