Who invented the computers and software we use daily?<\/strong><\/p>\n

(No, the answer is not Al Gore, though I was surprised at how much he did help get the web going<\/a>.)<\/p>\n

There are large and sharp distinctions between conceptualizing or inspiring a technology, making a working version of it<\/span>, funding it and popularizing it .\u00a0<\/strong><\/p>\n

This annotated list is about those few who created the first physical equipment and software landmarks in computer technology we all depend upon today.<\/strong><\/p>\n

It is not about those who may have inspired, funded or popularized technology. In a sense this article is an attempt to correct the errors in the computer field due to Stigler’s Law<\/a> – where typically the wrong people get the credit for ideas other people made first.<\/strong><\/p>\n

With appropriate respect, those who Imagine and Inspire an idea<\/span> (such as H.G. Wells<\/a>, Ray Bradbury<\/a> and Gene Roddenberry<\/a>) are vital because without new ideas – we wouldn’t have fire or aircraft.<\/strong><\/p>\n

Those who Popularize<\/span> <\/strong>(think Steve Jobs)\u00a0<\/strong> are valuable because maybe an invention’s value is too obscure or complex for many people to appreciate.<\/strong><\/p>\n

Funders<\/span> are important to help spread ideas rapidly (whether the ideas are good for our world or not<\/a> — as in “Can I serve you a glass of Thalidomide<\/a>?”).<\/strong><\/p>\n

But the key people are those who actually make the first examples of working things, called Inventors<\/a>, because without them — there is nothing to popularize or fund. Sometimes an inventor needs to take on all these roles.<\/strong><\/p>\n

This article celebrates the inventors of computer technology. <\/strong><\/p>\n

II. Software<\/strong><\/p>\n

First Computer Program<\/span>: The answer seems to be Heron of Alexandria in 60 AD who reportedly built machines which followed a series of instructions<\/a>.\u00a0<\/strong>(And of course, since one cannot run a program without a computer, this means the first, obviously non-electric, computers were the ones which used these programs. Perhaps not coincidentally, this is the same time-frame when the Antikythera device<\/a> was made.)<\/p>\n

The Jacquard loom of 1801<\/a> used different programs – without changing the machine.<\/strong><\/p>\n

The first program using electric devices was undoubtedly a set of instructions written in machine code<\/a>, but who did it is unclear. Possibly George Robert Stibitz<\/a> in 1937 or Konrad Zuse<\/a> in 1946. <\/strong><\/p>\n

(While Ada Lovelace-Byron <\/a>did write a set of programming instructions, just like Charles Babbage who inspired her but never built a working computer, Ada’s program never ran during her lifetime).<\/em><\/p>\n

First Operating System<\/a><\/span>: Director Tape program, John Frankovich and Frank Helwig, 1952<\/strong><\/p>\n

First Operating System<\/a> for Microcomputers<\/a><\/span>: CP\/M<\/a>, Gary Kildall<\/a>, 1974<\/strong>
\n Kildall created the first structured published interface between computer chips and computer components \u2013 allowing standardization. Called CPM (Control Program for Microcomputers) it is what DOS and now Windows is based on. <\/strong><\/p>\n

\u201cKildall was one of the first people to see microprocessors as fully capable computers rather than equipment controllers and to organize a company around this concept.\u201d<\/em><\/strong><\/p>\n

(Note: Bill Gates\/Microsoft \/ Tim Paterson\/Seattle Computer did not invent the microcomputer operating system. Further, Tim Paterson admits he copied CP\/M’s Application Programming Interface<\/a> and violated CP\/M’s copyright so “his” system would be compatible; to make it easier for application programmers to translate their CP\/M software to the 8086 chip.)<\/strong><\/p>\n

Paterson writes “What may be most surprising about the issue is that there is no significant dispute on the actual relationship between DOS and CP\/M. The relationship is simply this: DOS implements the same Application Program Interface (API) as CP\/M. The API is how an application program (such as a word processor) asks the operating system to perform a task, such as to read or write a disk file.<\/a>“<\/strong><\/p><\/blockquote>\n

Some highly informed people, including the late Kildall, believed that QDOS \/ PC-DOS was “reverse engineered” (or disassembled\/decompiled<\/a>) from CP\/M-86, because of its virtually identical internal structure and processes that goes far beyond<\/span><\/em> just copying Kildall’s API. Of course that would mean Gates\/Paterson didn’t even invent DOS. Paterson claims “To this day, I have never seen any CP\/M code.<\/a>“<\/strong><\/p>\n

However is this intentionally vague? Because Paterson is well aware that “code” can mean two things, source code or machine code, one of which makes his claim false. Paterson admits extreme familiarity with CP\/M’s internal working mechanisms<\/a>, and while he may never have seen any “Source code” – he clearly has worked with CP\/M’s “machine code<\/a>.”<\/strong>
\n Similarly, I had never seen any of Digital Research<\/a>‘s Concurrent CP\/M source code, but that did not prevent me from diagnosing and solving a problem with its hard disk routines.)<\/strong><\/p>\n

First Multi-Tasking (and Multi-user) Operating System for Microcomputers<\/span>: MP\/M<\/a>: Tom Rolander and Cathy Stratinski, while working for Kildall’s Digital Research<\/a>, 1979<\/strong><\/p>\n

First Search Engine<\/span>: Archie, Alan Emtage<\/a>, 1990.<\/strong><\/p>\n

(Note: Google did not invent Search Engines, they did make search dramatically better and more popular.)<\/p><\/blockquote>\n
