Jay Wright Forrester
Jay Wright Forrester (July 14, 1918 – November 16, 2016) was a pioneering American computer engineer and systems scientist. He is credited with being one of the inventors of magnetic core memory, the predominant form of random-access computer memory during the most explosive years of digital computer development (between 1955 and 1975). It was part of a family of related technologies which bridged the gap between vacuum tubes and semiconductors by exploiting the magnetic properties of materials to perform switching and amplification. He is also believed to have created the first animation in the history of computer graphics, a "jumping ball" on an oscilloscope. Later, he was a professor at the MIT Sloan School of Management, where he introduced the Forrester effect describing fluctuations in supply chains, and is credited as the founder of system dynamics, which deals with the simulation of interactions between objects in dynamic systems and is most often applied to researc ...

John R
John R. (born John Richbourg, August 20, 1910 - February 15, 1986) was an American radio disc jockey who attained fame in the 1950s and 1960s for playing rhythm and blues music on Nashville radio station WLAC. He was also a notable record producer and artist manager. Richbourg was arguably the most popular and charismatic of the four announcers at WLAC who showcased popular African-American music in nightly programs from the late 1940s to the early 1970s. (The other three were Gene Nobles, Herman Grizzard, and Bill "Hoss" Allen.) Later rock music disc jockeys, such as Alan Freed and Wolfman Jack, mimicked Richbourg's practice of using speech that simulated African-American street language of the mid-twentieth century. Richbourg's highly stylized approach to on-air presentation of both music and advertising earned him popularity, but it also created identity confusion. Because Richbourg and fellow disc jockey Allen used African-American speech patterns, many listeners thought that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Ginsburg
Charles Paulson Ginsburg (July 27, 1920 – April 9, 1992) was an American engineer and the leader of a research team at Ampex which developed one of the first practical videotape recorders. Biography Ginsburg was born on July 27, 1920 in San Francisco, California. At the age of two, he was diagnosed with type 1 diabetes. He attended Lowell High School in San Francisco. Ginsburg earned a bachelor's degree from San Jose State University in 1948. He worked as an engineer at AM-radio station KQW (now KCBS). He joined Ampex in 1951, and remained there until his retirement in 1986, holding the title Vice President of Advanced Technology. The engineering team that helped create the videotape recorder while working for Ampex under his direction in early 1956 were Charles Andersen, Ray Dolby, Shelby Henderson, Fred Pfost, and Alex Maxey. Ginsburg was elected a member of the National Academy of Engineering in 1973, being cited for invention and pioneering development of video magneti ...

Hidetsugu Yagi
was a Japanese electrical engineer from Osaka, Japan. When working at Tohoku Imperial University, he wrote several articles that introduced a new antenna designed by his assistant Shintaro Uda to the English-speaking world. The Yagi antenna, patented in 1926, allows directional communication using electromagnetic waves, and is now installed on millions of houses throughout the world for radio and television reception. He also tried, unsuccessfully, to introduce a wireless power transmission system. He participated in establishing the Chiba Institute of Technology. He was the fourth president of Osaka University from February 1946 to December 1946. In 1942, he became the President of Tokyo Institute of Technology, in 1944 he became the President of the Technical Institution, and in 1946 also the President of the Osaka Imperial University. He was decorated with the Medal of Honor with Blue Ribbon Award in 1951, with the Order of Culture in 1956, and posthumously with the Gr ...
