1898 – Birth of Harold Stephen Black. The American electrical engineer who discovered and developed the negative-feedback principle, in which amplification output is fed back into the input, thus producing nearly distortion less and steady amplification. In 1921, Black joined the forerunner of Bell Labs, in New York City, working on elimination of distortion

1956 – The first practical commercial black-and-white video recorder was demonstrated at a broadcast convention in Chicago and simultaneously in Redwood City, Ca. The VT-100 by Ampex Corporation was the size of a deepfreeze with an additional five 6-foot racks of circuitry. The 2-inch wide magnetic tape moved at a speed of 15 inches per second.

1943 – A proposal for an electronic computer was submitted to colleagues at the U.S. Army’s Ballistics Research Laboratory by John Grist Brainerd, director of research at the University of Pennsylvania’s Moore School, where the proposal was written by John Mauchly. In May 1943, the Army contracted the Moore School to build ENIAC, the first electronic computer. ENIAC marked a major step forward in computing.

1912 – David Sarnoff picked up a message of distress call of the Titanic relayed from ships at sea: “S.S. Titanic ran into iceberg, sinking fast.” Sarnoff, aged 21, was a telegraph operator managing a powerful Marconi radio telegraph station on top of Wannamaker’s department store in New York. He stayed at his post for 72 hours, receiving and transmitting the first authentic information on the disaster.

11 April

1908 – Masaru Ibuka was born. He was the Japanese electronics pioneer who co-founded a small post-war radio-repair company that grew into the giant Sony Corporation. He changed the Japanese electronics industry from simply copying Western products to innovation with their own electronic products. He introduced transistor technology to Japan.
1984 – Space Shuttle Challenger astronauts completed the first in-space satellite repair. George Nelson and James Van Hoften retrieved the ailing Solar Max astronomy satellite. It had originally been launched in 1980, but had been malfunctioning.

9 April

1919 – J. Presper Eckert Jr. was born. He was the American engineer and inventor of the first general-purpose electronic computer, a digital machine that was the prototype for most computers in use today. In 1946, Eckert with John W. Mauchly fulfilled a government contract to build a digital computer to be used by the U.S. Army for military calculations. They named it ENIAC for Electronic Numerical Integrator and Computer. By 1949, they had started a manufacturing company for their BINAC computer. This was followed by the establishment of the business-oriented computer company UNIVAC.

1865 – Charles Proteus Steinmetz, German-American electrical engineer was born. He was the inventor whose theories and mathematical analysis of alternating current systems helped establish them as the preferred form of electrical energy in the United States, and throughout the world. His early research on hysteresis (loss of power due to magnetic resistance) led him to study alternating current, which could eliminate hysteresis loss in motors. He was responsible for the expansion of the electric power industry in the U.S.

8 April

1959 – The Department of Defense called a meeting at the University of
Pennsylvania to define the objectives for a new Common Business Computer Language. Captain Grace Hopper led the group that kicked off the development of COBOL.

1947 – The largest sunspot group recorded was observed on the sun’s southern hemisphere. Its size was estimated at 7 billion square miles, or an area of 6100 millionths of the Sun’s visible hemisphere.

1886 – German scientist, Dr. Carl Gassner, was issued a German patent for the first “dry” cell, which used zinc as its primary ingredient. He encased the cell chemicals in a sealed zinc container. Gassner’s battery was much like the carbon-zinc, general-purpose batteries on the market today.

1885 – Granville T. Woods, a prolific black American inventor, patented an “Apparatus for Transmission of Messages by Electricity,” No. 315,368. In the following years he introduced numerous innovations for use on railroads, applying electricity for telegraphy, brakes, overhead conductors, controls and an electric railway.

1927 – The Bell System sent live TV images of Herbert Hoover, then the Secretary of Commerce, over telephone lines from Washington, D.C. to an auditorium in Manhattan. It was the first public demonstration in the US of long distance television transmission.

1959 – The first distinguishable echo was recorded of a radar signal bounced off the Sun—considered a milestone in the emerging field of radar astronomy. A three-person team from the Radioscience Laboratory, Stamford University, led by electrical engineering Professor Von R. Eshleman, recorded an echo from the outer corona of the sun, 17 min. after transmission. They used an IBM computer for signal processing.

1964 – IBM unveiled the System/360 line of mainframe computers, its most successful computer system. It was called the “360” because it was meant to address all possible sizes and types of customer with one unified software compatible architecture.
