Mr. Babbage
The Father of Modern-day Computers

Charles Babbage was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.

Babbage is considered by some to be "father of the computer". He is credited with inventing the first mechanical computer, the Difference Engine, that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in his Analytical Engine, programmed using a principle openly borrowed from the Jacquard loom. Babbage had a broad range of interests in addition to his work on computers covered in his 1832 book Economy of Manufactures and Machinery.

He was an important figure in the social scene in London, and is credited with importing the "scientific soirée" from France with his well-attended Saturday evening soirées. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century.

Babbage, who died before the complete successful engineering of many of his designs, including his Difference Engine and Analytical Engine, remained a prominent figure in the ideating of computing. Parts of his incomplete mechanisms are on display in the Science Museum in London. In 1991, a functioning difference engine was constructed from the original plans.

Jacquard  loom

Further Readings  

The Jacquard machine is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom. The machine was patented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740). The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design.

Analytical  Engine

Further Readings  

The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator. The analytical engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete. In other words, the structure of the analytical engine was essentially the same as that which has dominated computer design in the electronic era. The analytical engine is one of the most successful achievements of Charles Babbage. Babbage was never able to complete construction of any of his machines due to conflicts with his chief engineer and inadequate funding. It was not until 1941 that Konrad Zuse built the first general-purpose computer, Z3, more than a century after Babbage had proposed the pioneering analytical engine in 1837.

Difference  Engine

Further Readings  

A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage. The name difference engine is derived from the method of divided differences, a way to interpolate or tabulate functions by using a small set of polynomial co-efficients. Some of the most common mathematical functions used in engineering, science and navigation are built from logarithmic and trigonometric functions, which can be approximated by polynomials, so a difference engine can compute many useful tables.

Published  Book

Further Readings  

In this famous book, first published in 1832, Charles Babbage (1791-1871), the mathematician, philosopher, engineer and inventor who originated the concept of a programmable computer, surveys manufacturing practices and discusses the political, moral and economic factors affecting them. The book met with hostility from the publishing industry on account of Babbage's analysis of the manufacture and sale of books. Babbage describes the many different printing processes of the time, analyses the costs of book production and explains the publication process, before discussing the 'too large' profit margins of booksellers. Babbage succeeded in his aim 'to avoid all technical terms, and to describe in concise language', making this an eminently readable historical account. His analysis and promotion of mechanisation and efficient 'division of labour' (still known as the 'Babbage principle') continue to resonate strongly for modern industrial engineering.

A Brief History of CBI 1978: Founded by Erwin and Adelle Tomash as the International Charles Babbage Society; office opened in Palo Alto, California. 1979: American Federation of Information Processing Societies becomes principal sponsor of the Society; Society renamed the Charles Babbage Institute; companies and individuals in the information industries offer support. 1980: University of Minnesota enters into a legal agreement to sponsor and house the Charles Babbage Institute; a new supporting entity, the Charles Babbage Foundation, is created to govern the Institute as a partner with the University. 1989: University of Minnesota assumes all authority for the Charles Babbage Institute; CBI becomes an organized research unit of the University. 2018: As part of restructuring within the College of Science and Engineering, CBI became a research center of the Graduate Program in the History of Science, Technology, and Medicine.
