American inventor known as "The Father of Radio Control" and son of mining engineer John Hays Hammond, Sr.
At the age of twelve he met Edison, the boy asked so many questions that the inventor gave him a personal tour of the complex and assumed the role of mentor. The two would remain in contact for the rest of Edison’s life. While studying at the Sheffield Scientific School of Yale University, Hammond became interested in the new study of radio waves and he was taken under the wing of Alexander Graham Bell. Bell also became his mentor and the two would remain close friends until Bell’s death.
After he became an authority on the patent process, he founded the Hammond Radio Research Laboratory on his father’s estate inGloucester, Massachusetts. In total, he is credited with more than 800 foreign and domestic patents on more than 400 inventions (the exact number of inventions is vague due to how credit was listed on the forms) mostly in the fields of radio control and naval weaponry.
He died 12 February 1965.
