Today (January 31, 1954) is the anniversary of Edwin Armstrong's discovery of the world's first radio station (F.M.).

Edwin Howard Armstrong (born 18 December 1890 in Chelsea, New York, USA) is the father of John and his mother is Emily. His father worked at Oxford University Press and later took a Theta G course at Columbia University. He first became a professor at Columbia University, where he served as a signal officer during World War I. He invented the FM radio and broadcast it in New Jersey in 1935. Since then, his product has been used by many private companies but has not been renamed. The court ruled in his favour but said no one understood what FM was.

He is one of the most memorable figures in the history of radio use through sound modulation. He patented the world's first FM broadcast. It was patented in 1941 for his renewable circuit. He then patented the second advanced renewable circuit in 1933. In 1918 he developed the superheterodyne receiver. He revolutionized radio broadcasting by bringing modern frequency multiplication (FM). He was forced into a crisis at his job due to the financial crisis and stress. In addition, their wife Marine McLean moved to another apartment to see her sister. Edwin Armstrong, the inventor of the world's first radio station (F.M.), committed suicide by jumping from a terrace in New York on January 31, 1954, at the age of 63.
