Louis W. Parker was born in Budapest, Hungary on January 1, 1906. He received his primary and secondary education in Hungary, and following his graduation in 1923, he immigrated to the United States, becoming a naturalized citizen in 1932. After learning the language of the U.S., he studied at the City College of New York.

He first gained publicity in 1929 with a hotel radio system when he used low frequency radio signals to broadcast over the electric wires within the building. This made it possible to receive noise-free reception while using only one-tube receivers. Later, he worked on radio direction finders for airplanes and cathode ray oscilloscopes which led to work on television and closed circuit television systems.

During the Second World War, he designed and manufactured portable radio transmitters for military use. After the war, he created the invention for which he is best known--the so-called "Intercarrier Sound System" used in all television receivers in the world. In 1965, it was estimated that more than 100,000,000 receivers had been built using this invention. Without it, television receivers would not work as well and would be far more costly.

Among some of Parker's more notable inventions is the first color television system using vertical color lines which made it possible to change from the original three-color dot system to the simpler vertical color line system. Most of the present color television receivers in the world now use this system.

Later, he invented electrical instruments operating on somewhat different principles which were greatly superior in performance and which were the basis for the Parker Instrument Corporation. The company was chosen by the National Aeronautics and Space Administration (NASA) to furnish selected instruments for use in the manned Apollo flights to the moon.

He was honored by Nova University in 1970 with the honorary degree of Doctor of Science for his contributions to humanity, as well as to Fort Lauderdale and Broward County.

During his lifetime, Dr. Parker had more than 200 United States and foreign patents.
