1, Herman Hollerith:
Herman hollerith (English: herman hollerith, 65438+February 29th, 0860-1929 65438+10/7), born in Buffalo, is a German-American statistician. 1896, watchmaking company was established, and later became the predecessor of IBM (the predecessor of computer).
2. Vaniva Bush:
Nivard Bush (1890.3.1~1974.6.26) was one of the greatest American scientists and engineers during World War II.
He is a pioneer of analog computers, and Shannon, the father of information theory, is his student. 1945 published the paper "As We Think", put forward the concept of miniature photography technology and memex, and started the era of digital computers and search engines. In this paper, many theories put forward by Van Neva predict the development of computers in the decades since World War II. Many pioneers in the computer field were inspired by this article, and later computer technologies such as mouse and hypertext were based on this theoretical paper.
No matter which field you look at in the history of information technology development, Bush is a visionary pioneer, leaving footprints there. As historian Michael Shelley said, "To understand the world of Bill Gates and Bill Clinton, you must first understand Vanessa Bush." It is precisely because of his many contributions in the field of information technology and superhuman foresight that Vanessa Bush won the reputation of "the godfather of the information age".
3. john von neumann:
John von neumann (1903~ 1957), originally from Hungary, holds a doctorate in mathematics from Budapest University. One of the most important mathematicians in the 20th century, and one of the scientific generalists in the fields of modern computer, game theory, nuclear weapons, biochemical weapons, etc., was called "the father of computer" and "the father of game theory" by later generations.
From 65438 to 0946, von Neumann began to learn programming. He is one of the founders of modern numerical analysis and computational mathematics. He first studied the numerical calculation of linear algebra and arithmetic, then focused on the discretization and stability of nonlinear differential equations, and gave the error estimation. He helped develop some algorithms, especially the Monte Carlo method.
To put it simply, his quintessential contribution is two points: binary thought and program memory thought.
Von Neumann's greatest contribution to mankind is his pioneering work in computer science, computer technology, numerical analysis in economics and game theory.
4. Bill Gates:
Bill Gates? (Bill Gates), full name William Henry Gates III, is short for Bill or Gates. 1955/kloc-0 was born in Seattle, Washington, USA on October 28th. He is an entrepreneur, software engineer, philanthropist and founder of Microsoft Corporation. Former chairman, CEO and chief software designer of Microsoft.
Under his leadership, a new generation of computer system has been successfully established, and the way of life of human beings has been changed imperceptibly. With the computer age entering a new era, an era of harmonious man-machine communication.
5. Steve Jobs:
Steve Jobs is one of the former chief operating officers and founders of Apple and the former chairman and CEO of Pixar Animation Company (Pixar was acquired by Disney in 2006). Jobs is also a member of the board of directors and the largest individual shareholder of Disney Company. Jobs is regarded as an iconic figure in the computer industry and entertainment industry, and also as the creator of well-known digital products such as Macintosh, ipad, iPod, iTunes Store and iPhone.
