Title: ENIAC
Content:   ENIAC (Electronic Numerical Integrator and Computer) was the first programmable, electronic, general-purpose digital computer made in 1945. It was Turing-complete and able to solve "a large class of numerical problems" through reprogramming. Although ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory (which later became a part of the Army Research Laboratory), its first program was a study of the feasibility of the thermonuclear weapon. ENIAC was completed in 1945 and first put to work for practical purposes on December 10, 1945. ENIAC was formally dedicated at the University of Pennsylvania on February 15, 1946, having 
Title: ENIAC Day
Content:  ENIAC Day or the World’s First Computer Day is celebrated on February 15. On February 10, 2011, the City of Philadelphia officially declared that February 15, 2011 - the 65th anniversary of the unveiling of the Electronic Numerical Integrator and Computer (ENIAC), the world's first general-purpose electronic computer, developed at the University of Pennsylvania's Moore School of Electrical Engineering - would that year and henceforth be known as ENIAC Day.
Title: First Draft of a Report on the EDVAC
Content:  The First Draft of a Report on the EDVAC (commonly shortened to First Draft) is an incomplete 101-page document written by John von Neumann and distributed on June 30, 1945 by Herman Goldstine, security officer on the classified ENIAC project. It contains the first published description of the logical design of a computer using the stored-program concept, which has controversially come to be known as the von Neumann architecture.
Title: University of Cambridge
Content:  the world's first computing system as early as the mid-1800s. Alan Turing went on to devise what is essentially the basis for modern computing and Maurice Wilkes later created the first programmable computer. The webcam was also invented at Cambridge University, showing the Trojan Room coffee pot in the Computer Laboratories. In physics, Ernest Rutherford who is regarded as the father of nuclear physics, spent much of his life at the university where he worked closely with E. J. Williams and Niels Bohr, a major contributor to the understanding of the atom, J. J. Thomson, discoverer of the electron, Sir James

Title: Programmer
Content:  British countess and mathematician Ada Lovelace is often considered to be the first computer programmer, as she was the first to publish part of a program (specifically an algorithm) intended for implementation on Charles Babbage's analytical engine in October 1842. The algorithm was used to calculate Bernoulli numbers. Because Babbage's machine was never completed as a functioning standard in Lovelace's time, she never had the opportunity to see the algorithm in action. The first person to execute a program on a functioning, modern, electronic computer was the computer scientist Konrad Zuse in 1941. The ENIAC programming team, consisting of Kay McNulty, Betty Jennings, Betty Snyder, Marlyn Wescoff, Fran Bilas and Ruth Lichterman, have been credited as the first regular computer programmers.
Title: First university in the United States
Content:  as 1746—the date of its first charter, however, the exact words of the charter are unknown, the number and names of the trustees in the charter are unknown, and no known copy is extant ). Penn's claim as the first university in the United States is three-fold: the 1765 founding of the first medical school in America made Penn the first institution to offer both "undergraduate" and professional education; the 1779 charter made it the first American institution of higher learning to take the name of "University"; and existing colleges were established as seminaries (although, as detailed in its own article, Penn adopted a traditional seminary curriculum as well). 
Title: 1945 in science
Content: June 30 – Distribution of John von Neumann's First Draft of a Report on the EDVAC, containing the first published description of the logical design of a computer with stored-program and instruction data stored in the same address space within the memory (von Neumann architecture). ; July – Publication of Vannevar Bush's article "As We May Think" proposing a proto-hypertext collective memory machine which he calls 'memex'. ; November – Assembly of the world's first general purpose electronic computer, the Electronic Numerical Integrator Analyzer and Computer (ENIAC), is completed in the United States, covering 1800 sqft of floor space, and the first set of calculations is run on it.

Content:  of reinvention and change in management education". Several major scientific discoveries have also taken place at Penn. The university is probably best known as the place where the first general-purpose electronic computer (ENIAC) was born in 1946 at the Moore School of Electrical Engineering. It was here also where the world's first spelling and grammar checkers were created, as well as the popular COBOL programming language. Penn can also boast some of the most important discoveries in the field of medicine. The dialysis machine used as an artificial replacement for lost kidney function was conceived and devised out of a pressure cooker
