According to a recent book (Early FM Radio, by Frost), modern FM wasn't invented all at once, but evolved with the help of dozens of other people besides Armstrong. But Armstrong was the first to significantly widen the frequency swing. A hand-drawn sketch indicates that he hit on that idea in the summer of 1932. During the following January he filed two patent applications for wide-band FM, one of which has a similar sketch. On December 26, 1933, he was awarded four patents for FM radio (The other two were applied for in 1927 and 1930, but weren't for wide-band). He discovered in early 1934 that his invention was almost free of static.
Armstrong took a few more years to give FM high fidelity, but by 1938 or 1939 he had improved FM to the point that it was our FM radio, minus the stereo sound.
No, he did not, but he was certainly important in radio's growth and development. Edwin Howard Armstrong invented what we today know as FM radio. (Early radio used only the AM process to add sound to a radio wave.) Armstrong's invention improved the quality of the sound and made radio less likely to be affected by static.
Edwin Armstrong did not invent radio, however he invented several improvements to radio.1913, the regenerative circuit (making oscillators possible, making the earlier sparkgap radios obsolete)1917 to 1919, superheterodyne radio receivers1921, super-regenerative radio receiversmiddle 1920s, frequency modulationEdwin Armstrong received 42 patents in total.
The FM radio was invented in 1933. It was invented by the inventor Edwin Howard Armstrong. He invented the frequency that allows radios to work.

Edwin Howard Armstrong invented several things, but he is best known for inventing what we today know as FM radio. (Early radio was only on the AM band.) Armstrong's invention improved the quality of the sound and made radio less likely to be affected by static.

he did not invent anything but he was the first man to land on the moon
In 1917, he received the Institute of Radio Engineers Medal of Honor. In 1919, the French government gave him the Legion of Honor. In 1941, he received the Franklin Medal. In 1942, he received the AIEE's Edison Medal.
Guglielmo Marconi is credited with the invention of the radio in the late 19th century. He successfully transmitted radio signals across the Atlantic Ocean in 1901, marking a significant milestone in the development of wireless communication.

By 1937, radio had long been known as "radio." But if you had been around in the early 1920s, radio was called a number of things-- wireless, wireless telephone, radiophone, and radio telephone. By the mid-1920s, however, the other words had fallen out of use, and radio was in fact only called "radio." What is interesting about 1937 is that FM was beginning to get into the news. In radio's first several decades, all stations were on AM. But in the late 1930s, inventor Edwin Howard Armstrong was demonstrating his new way of broadcasting-- which was generally referred to as "static-free radio"-- since AM signals tended to pick up all kinds of interference from the atmosphere, whereas FM signals did not.
