Charles Babbage

 

Known to many as the “Father of Computing” but remembered as a practical scientist, Charles Babbage, a nineteenth century mathematician and inventor, was born with the knowledge to design a modern machine.  Unfortunately, the technology necessary to create the first computer was not yet developed.  Babbage’s grandness, eccentricities, and continuous tinkering got in the way of the completion of his great “works”.

Born December 26, 1792 in Teignmouth, Devonshire UK, the son of a London banker, Charles Babbage was afforded the luxury of private tutors, was well read and was accepted into Trinity College, Cambridge in October 1810.  Disappointed with the mathematical instruction available at Cambridge, he joined with other friends to form the Analytical Society.  By 1812, Babbage transferred to Peterhouse, Cambridge where he served as the top mathematician.  Babbage would fail to graduate, instead receiving an honorary degree without examination in 1814.

During his twenties, Babbage worked as a mathematician, was elected as a Fellow of the Royal Society in 1816, and played a prominent part in the foundation of the Astronomical Society in 1820.  It was during this time that he became convinced that a machine could be designed to compile mathematical tables.  Babbage tired of the monotony of calculations began, work on what would become the Difference Engine; a programmable machine with a 20-decimal capacity.  His invention passion was born.  The Royal Society, highly supportive of Babbage’s prototype, convinced the British government to award Babbage an initial 1500 pounds in public funding.  Babbage confidently reported that his mechanical machine would be complete in less than three years; however, a working model of the Difference Engine proved much more difficult to build.  Babbage spent the next ten years modifying and re-designing the device and spent millions of governmental money.  With no working model and millions of dollars invested, the government finally withdrew their funding, retaining ownership of the machine; it remains today in the London Science Museum.  In 1991, working from Babbage’s original plans, the Difference Engine was completed and functioned perfectly. Nine years later in 2000, the Science Museum completed the printer. 

            Babbage was quickly back to work after failing to bring his Difference Engine to completion.  By 1833 he began construction on a more complex Analytical Engine, a machine that could be programmed using punch cards and employ sequential control, branching, and looping (all features used in modern day computers).  Throughout this time, Babbage relied heavily on the brilliance of Ada Byron, Countess of Lovelace, fellow mathematician and confidant.  She was one of a few who understood Babbage’s vision and saw the potential of the Analytical Engine.    

As a true inventor, Babbage was constantly inventing.  His ideas did not end with mathematical engines.  Babbage invented the cow-catcher, England’s uniform postal rates, occulting lights for lighthouses, the first reliable actuarial tables, and skeleton keys.  He designed a printer for the Difference Engine #2, a remarkable feat for a mid-nineteenth century mathematician.

            Charles Babbage was an outcast among his peers and rarely interacted with with those outside his academic circle.  He considered himself better than the “common man”.  Babbage considered street music an utmost nuisance.  He constantly filed complaints; therefore, the public tormented him with an unending parade of musicians parading past his windows.  Most who came in contact with him considered him an eccentric, and he had a common distaste for commoners.  Neither his neighbors nor his countrymen understood his mind or his interests.  Babbage once counted all the broken panes of glass of a factory, publishing his findings.  His obsession with fire led him to bake himself in an oven at 265 degrees for four minutes to see what would happen.  He found there to be not much discomfort.  Not to have been challenged enough in the oven, he headed abroad and arranged to be lowered into the center of Mount Vesuvius in order to view the molten lava for himself.

            At the time of his death in 1871, few people knew of Babbage or his contributions.  The Royal Society printed no obituary and the Times ridiculed him.  He had arranged for his brain to be preserved in alcohol.  It later was dissected by Sir Victor Horsley of the Royal Society in 1908.  A crater on the moon is named for Charles Babbage. The use of Jacquard punch cards, of chains and subassemblies, and ultimately the logical structure of the modern computer, all come from Babbage inventions.  Many modern day scientists consider Babbage a profound thinker of the nineteenth century and an important link in the chain of computing.
