Eckert–Mauchly Computer Corporation
The Eckert–Mauchly Computer Corporation (EMCC) (March 1946 – 1950) was founded by J. Presper Eckert and John Mauchly. It was incorporated on December 22, 1947. After building the ENIAC at the University of Pennsylvania, Eckert and Mauchly formed EMCC to build new computer designs for commercial and military applications. The company was initially called the Electronic Control Company, changing its name to Eckert–Mauchly Computer Corporation when it was incorporated. In 1950, the company was sold to Remington Rand, which later merged with Sperry Corporation to become Sperry Rand, and survives today as Unisys. Founding Before founding Eckert–Mauchly Computer Corporation, Mauchly researched the computing needs of potential clients. Over a period of six months in 1944 he prepared memos and kept detailed notes of his conversations. For instance, Mauchly met with United States Census Bureau official William Madow to discuss the computing equipment they desired. Th ...

UNIVAC 1 Demo
UNIVAC (Universal Automatic Computer) was a line of electronic digital stored-program computers starting with the products of the Eckert–Mauchly Computer Corporation. Later the name was applied to a division of the Remington Rand company and successor organizations. The BINAC, built by the Eckert–Mauchly Computer Corporation, was the first general-purpose computer for commercial use, but it was not a success. The last UNIVAC-badged computer was produced in 1986. History and structure J. Presper Eckert and John Mauchly built the ENIAC (Electronic Numerical Integrator and Computer) at the University of Pennsylvania's Moore School of Electrical Engineering between 1943 and 1946. A 1946 patent rights dispute with the university led Eckert and Mauchly to depart the Moore School to form the Electronic Control Company, later renamed Eckert–Mauchly Computer Corporation (EMCC), based in Philadelphia, Pennsylvania. That company first built a computer called BINAC (BINary Automa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop Corporation
Northrop Corporation was an American aircraft manufacturer from its formation in 1939 until its 1994 merger with Grumman to form Northrop Grumman. The company is known for its development of the flying wing design, most successfully the B-2 Spirit stealth bomber.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 93-106, Cypress, CA, 2013. . History Jack Northrop founded 3 companies using his name. The first was the Avion Corporation in 1928, which was absorbed in 1929 by the United Aircraft and Transport Corporation as a subsidiary named "Northrop Aircraft Corporation" (and later became part of Boeing). The parent company moved its operations to Kansas in 1931, and so Jack, along with Donald Douglas, established a "Northrop Corporation" located in El Segundo, California, which produced several successful designs, including the Northrop Gamma and Northrop Delta.

BINAC
BINAC (Binary Automatic Computer) was an early electronic computer designed for Northrop Aircraft Company by the Eckert–Mauchly Computer Corporation (EMCC) in 1949. Eckert and Mauchly, though they had started the design of EDVAC at the University of Pennsylvania, chose to leave and start EMCC, the first computer company. BINAC was their first product, the first stored-program computer in the United States; BINAC is also sometimes claimed to be the world's first commercial digital computer even though it was limited in scope and never fully functional after delivery. Architecture The BINAC was a bit-serial binary computer with two independent CPUs, each with its own 512-word acoustic mercury delay-line memory. The CPUs continuously compared results to check for errors caused by hardware failures. It used approximately 700 vacuum tubes. The 512-word acoustic mercury delay-line memories were divided into 16 channels, each holding 32 words of 31 bits, with an addi ...

Ambler, Pennsylvania
Ambler is a borough in Montgomery County, Pennsylvania. It is located approximately 16 miles (26 km) north of the Center City Philadelphia. History Lenape The historical territory of the Lenni Lenape was in the Delaware River Valley, in an area reaching from Cape Henlopen, Delaware, northward towards the lower Hudson Valley in southern New York. The area towards the south, including what is now Philadelphia and nearby Ambler, was the home of a linguistic group called the Unami. According to tradition, the Lenape established a peace treaty with Quaker William Penn in the 1680s. Harmer family William and George Harmer are listed among the Quakers who emigrated to Pennsylvania in 1682. In 1716, William and George Harmer purchased a 408-acre tract from William Penn, an area including most of what now is Ambler Borough. They are credited as the first landholders to actually settle in the area. William Harmer built a grist mill powered by the Wissahickon Creek, "the first co ...

McCarthyism
McCarthyism is the practice of making false or unfounded accusations of subversion and treason, especially when related to anarchism, communism and socialism, and especially when done in a public and attention-grabbing manner. The term originally referred to the controversial practices and policies of U.S. Senator Joseph McCarthy, and has its origins in the period in the United States known as the Second Red Scare, lasting from the late 1940s through the 1950s. It was characterized by heightened political repression and persecution of left-wing individuals, and a campaign spreading fear of alleged communist and socialist influence on American institutions and of espionage by Soviet agents. After the mid-1950s, McCarthyism began to decline, mainly due to Joseph McCarthy's gradual loss of public popularity and credibility after several of his accusations were found to be false, and sustained opposition from the U.S. Supreme Court led by Chief Justice Earl Warren on human rights ...

Jean Bartik
Jean Bartik ( Betty Jean Jennings; December 27, 1924 – March 23, 2011) was one of the original six programmers for the ENIAC computer. Bartik studied mathematics in school then began work at the University of Pennsylvania, first manually calculating ballistics trajectories and then using ENIAC to do so. The other five ENIAC programmers were Betty Holberton, Ruth Teitelbaum, Kathleen Antonelli, Marlyn Meltzer, and Frances Spence. Bartik and her colleagues developed and codified many of the fundamentals of programming while working on the ENIAC, since it was the first computer of its kind. After her work on ENIAC, Bartik went on to work on BINAC and UNIVAC, and spent time at a variety of technical companies as a writer, manager, engineer and programmer. She spent her later years as a real estate agent and died in 2011 from congestive heart failure complications. Content-management framework Drupal's default theme, ''Bartik'', is named in her honor.

Grace Hopper
Grace Brewster Hopper (; December 9, 1906 – January 1, 1992) was an American computer scientist, mathematician, and United States Navy rear admiral. One of the first programmers of the Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first linkers. Hopper was the first to devise the theory of machine-independent programming languages, and the FLOW-MATIC programming language she created using this theory was later extended to create COBOL, an early high-level programming language still in use today. Prior to joining the Navy, Hopper earned a Ph.D. in mathematics from Yale University and was a professor of mathematics at Vassar College. Hopper attempted to enlist in the Navy during World War II but was rejected because she was 34 years old. She instead joined the Navy Reserves. Hopper began her computing career in 1944 when she worked on the Harvard Mark I team led by Howard H. Aiken. In 1949, she joined the Eckert–Mauchly Co ...
