A Brief and Incomplete History of Computing from Ancient to Modern

I recently attended an event here in DC where Woz was the guest of honor.  I was unaware of his book at the time.  So leading up to it, I thought it would be fun to re-watch a couple of old documentaries in which he appears.  I forewent his foray into reality TV.  I chose to watch "The Machine that Changed the World" (youtube)  a PBS documentary  from 1992 which is farsighted enough to not feel completely dated plus the chronicling of the early history of computing is nicely  done.   The other was Robert X Cringley’s  1996 "Triumph of the Nerds" (youtube) which is a fun account of the rise of the personal computer.

ENAIC took up 1800 square feet

Watching these rekindled an idea I had to do a history of events from ancient to modern that got us to where we are now.  So I set forth to collect and list notable events that propelled both the science and industry of computing to its present state.  My goal was to include the people and events that not only shaped the technology but that also shaped the industry and the language we use to describe things.  One example is the term bug that many people may take for granted.  It is derived from a problem caused by an actual insect, a moth stuck in a relay.  The other and perhaps more profound case is that the word "computer", a name we also take for granted, was a historical accident.  Prior to 1940 a computer was a person who did computations or calculations.  Many of the first machines with the exception of the decryption work done Bletchley Park were developed for doing computations, specifically ENIAC, which was initially designed to calculate artillery firing tables.  ENIAC became the first well known computer and captured the public’s imagination when the "Giant Brain" was displayed to the American press in 1946.  Not long after that the word computer went from describing a person to a machine.  Meanwhile the Colossus machine from Bletchley Park, the project Alan Turing worked on, remained a secret until the 1970’s.  Had that work been made public immediately following the war we might be calling these machines decoders or decrypters and the history of the computer might have taken some different turns, who knows maybe even Silicon on Avon, okay that’s probably a stretch. 

As I was chronicling these events of which I tried to include when certain ideas and inventions occurred I noticed some interesting trends.  For example some ideas like the algorithm and robotics (or mechanical automata) are quite ancient going back over a thousand years.  Many of the technologies we use today date back mostly about 30 to 50 years ago and some are even older.  Magnetic storage was patented in 1878, making it 19th century technology, and if you think about it, it is really is fairly primitive, I‘ve heard hard disks described as "spinning rust".  Admittedly today’s hard disks contain very sophisticated electronics and electromechanics but are still technologically primitive (effectively sophisticated 19th century technology) compared to SSD technology, which is 20th century technology with DRAM from 1966 and NAND Flash being invented in 1980.  The real advances, not surprisingly, are the advances in materials science, fabrication and manufacturing that take 1970’s technological developments like the active matrix display technology and make them small, cheap and ubiquitous today.  

There are many interesting people who played very important and pivotal roles who seem to be largely forgotten.  One of my biggest pet peeves is the cult of personality effect that seems to show up in our industry and the worst case of it is probably Steve Jobs.  I remember working with one young fanboy who was telling me how great Steve Jobs was and that Steve Jobs thought of the iPad in the 1970s, to which I replied that it was depicted in a movie called 2001 from the late 1960s, which I would wager that Jobs had seen. I include that movie in my list of events because it does depict advanced computer technology.  While Steve Jobs seems to garner more attention than he deserves, and I do credit Apple with certain events that shaped the industry as it is today.  I think there are several more interesting people who have made much more substantial contributions. One person is Robert Noyce who cofounded Intel and invented the practical version of the integrated circuit that we use today, he was kind of a Jobs and Wozniak combo in terms of technical brilliance and business acumen.   Another interesting story surrounds ARPANET, the proto-internet.  While Al Gore may have tried to take credit for its invention, J. C. R. Licklider might have actually been the one who did effectively invent it.  He convinced Bob Taylor of the idea that became ARPANET.  Taylor is another of those people who deserves recognition as after he created the initial proposal for ARPANET he went on to lead Xerox Parc for about 15 years from its inception.   Also Xerox Parc often seems to get the credit for our much of our modern computing interfaces, but again Douglas Engelbart really deserves that credit as he demonstrated most of those ideas in 1968 two years before Xerox established Parc. He of course was a big influence of that work at Parc.

A big driving force for the creation of practical computer technology was the need for machines to do tedious laborious mental work like large quantities of calculations especially to create mathematical tables that gave values of various computations such as logarithms which were used extensively prior to the 1970s before the advent of affordable desktop and pocket scientific calculators.  Babbage’s work was aimed at solving this problem.  During world war two the need for the creation of artillery tables exceeded the available human labor which drove the military to fund the creation of ENIAC, which was not delivered until after the war.  The war also drove the Bletchley park work, again an attempt to automate tedious work of trying to manually decipher the coded messages of the Enigma Machine.

Big data circa 1950s. ~ 4GB of punched cards.

Big data is a common term today, but in many respects it has history going back over a hundred years and could be also considered a driver of the development of practical computer technology.  One continual source of big data was and probably still is, is collection of census data.  In 1889 Herman Hollerith developed an electromechanical tabulating machine that was used to process data for the 1890 US census.  His 1889 patent had the title "Art of Compiling Statistics" and he later established a company to sell the machines which were used worldwide for census and other applications. He is credited with laying the foundations of the modern information processing industry. His company was eventually merged with four others to become IBM.  In 1948 the US Census Bureau had a big data problem that was outgrowing the existing electromechanical technology.  John Mauchly one of the inventors of ENIAC and cofounder of Eckert–Mauchly Computer Corporation sold the census department on its successor named UNIVAC to handle census data.  The company survives today as Unisys.

A huge problem with software projects today is that of project failure and the history of computing seems to have its share as well.  Software projects sometimes outright fail and all too often are late and over budget.  Babbage’s Difference Engine project which was cancelled after 15 years and an expenditure that was ten times the original amount paid.  The failure was due to bad management on his part and what might be called scope creep in that he got distracted by designing the more general Analytical Engine.  UNIVAC is another notable early project that was delivered late and over budget.

The real challenge of a post like this is what to include. The Machine that Changed the World documentary starts with writing which was our first precise technique to record information. I went back farther to include the recording of numerical information. A big influence on the way I view history comes from a PBS show that aired in the eighties called Connections which was done by James Burke. In it he traces in a very engaging way various technological developments as cause and effect events. In a sense he demonstrated that history was an interesting living topic not the banal languid mimeographs that I experienced in school. I tried to choose events that were either the inception of something or the point at which it caused a significant change. In the spirit of Connections there are definite threads here, the thread of calculation and computation including number representation for those purposes. The thread of encryption also plays an important role as does dealing with information both in terms of storage, replication and processing. Some of the threads are obvious and some are more subtle.

If you made it this far you’ve survived my brief, relatively speaking, trip though five millennia of the human history of computing.  It was hard to pick more recent things since we don’t know what the important events for the future are.  I chose to end with Homototpy Type Theory since it is supposed to be the next big thing.  Also you might have noticed that my title is similar, perhaps an homage, or just a rip off of:  "A Brief, Incomplete, and Mostly Wrong History of Programming Languages".  I had this idea prior to seeing his and for a long time it deterred me from writing this, but I finally got over the perception that he did it first since my original idea was quite different.
