Leonardo Torres y Quevedo1 (1852-1936) was a superior engineer, pioneer of remote control, a "prolific and successful inventor"2, and creator of the what is believed to be the first chess automaton3--in effect, the first human-machine game where the machine answered back. (There are earlier examples of chess machines, perhaps the most famous/infamous of which is the celebrated "Turk", a faux chess automaton created in the 1770's by Wolfgang von Kempelen, a supposedly mechanical device taking on all comers performing at a very high level, except that it was a fraud, a model of a machine with a human inside of it making the decisions, a sort of reverse robot.)

Torres wrote very little, mainly because he didn't like to,4so mostly what is known of his work in print (outside of patent reports) is primarily a secondary source reporting on his efforts. There are three earlier appearances in print on the automaton--in Revista de la Real Academia de ciencias... de Madrid in 1913, La Nature5in 1914, and Asociación Española para el Progreso de las Ciencias, Congreso de Valladolid6, in 1915.
"In 1912 Torres built a robot capable of playing the chess endgame of king and rook against king and defeating a human adversary. This device, perfected in 1920, and the Telekino must be recognized as conceptually related to the calculating machine of Charles Babbage, as Torres Quevedo acknowledged in “Ensayos sobre automática. Su definición. Extensión teórica de sus definiciones” (Revista de la Real Academia de ciencias... de Madrid, 12 , 391–419). His work in this field culminated in an electromechanical calculating machine introduced 26 June 1920, the prototype of which demonstrated that calculations of any kind can be effected by purely mechanical processes. In 1913 Torres Quevedo had established that a machine could proceed by trial and error, in contrast with current belief–“at least when the rules that have to be followed in trial and error are precisely known...”--Dictionary of Scientific Biography, vol 13, pp 431-2.
The first appearance of the chess playing machine to appear in English seems to have been in the Scientific American Supplement, November 6, 1915, pp 296-298 (appearing with seven photographs of inventions three of which are for the chess machine, and four schemtics all of which pertain to the chess machine): "Torres and His Remarkable Automatic Devices, He Would Substitute Machinery for the Human Mind".
His superb creation, which he called "El Ajedrecista"7 ("the Chess Player") was an electromechanical device which pitted an endgame between a King/King-rook, and was fully and completely hand's-free functional. A later version attempted an improvement on this magnificent machine using magnets.
The machine was exhibited and demonstrated in 1951 by Torres' son, Gonzala, showing how the machine worked to the inventor of cybnertics, the big-brained Norbert Wiener. A photograph of the meeting appears in the Eames' great book, The Computer Perspective, though I downloaded this image (below) from Cybnertic Zoo:

This is a group of materials from the estate of Ralph Mullendore (see below), an early and integral team member of the electronic computation section of the U.S. Bureau of the Census, who was responsible for the installation and maintenance of the UNIVAC there, at Census. The papers are on their way to a history of computer science section at the library at North Carolina State University where they will hopefully be enjoyed by any and all who have an interest in the early stages of the maintenance and tinkerings on America's first commercial computer. It should be remembered that the hands of the man who wrote all of these notes were the same hands that worked on this monumentally important machine, the first of its kind in existence.
I thought for a moment that the Oxford English Dictionary had been scooped in identifying the earliest usage of the term "super computer" when I saw this newspaper article in the wonderful book by Charles and Ray Eames called A Computer Perspective (Harvard University Press, 1973). The article refers to an unidentified machine at Columbia University in a March 1, 1920 article, which would beat the first use found by the OED in 1927 (see below) by seven years. So, I checked this out a little, and latched onto a reference to Dr. Ben D. Wood as the director of the Statistical Bureau at Columbia, and found that this event didn't happen until June 19291.
And so the Eameses got this one wrong, or the editor did, or the proof reader, or the typesetter. So instead of being 1920, this is at the very least second-half 1929, some two years or so past the first use identified by the OED. It is also possible that this might be 1931/2. Still, this was very early for using the term, and the article is interesting.
More can be found on the machine (which was probably the "Columbia Machine", which as also known as the "Statistical Calculator" and the "Difference Tabulator", and with some affection "the Packard". A very good appraisal of this machine can be found at the Columbia University site for computing history at Columbia, http://www.columbia.edu/cu/computinghistory/packard.html

The UNIVAC (Universal Automatic Computer) was the first commercially-available electronic computer, and the first computer to handle both numeric and alphabetic information, produced by Remington Rand, and came into working service at the Bureau of the Census in 1951. It was designed by John Mauchly and Pres Eckert Jr, who also worked together in the design and construction of the first digital computer, the Electronic Numerical Integrator and Computer (the famous ENIAC). The UNIVAC was a Big Boy: 25x50', with 5,600 tubes, and 18,000 crystal diodes--given its workhorse nature and general success, by 1957 there were 46 UNIVACs in operation.
The following are working block diagrams of sections of the UNIVAC, produced by some sort of early offset process in 1950, slightly before the computer came to its working life. I have a number of sections of the computer represented in this way, but not the entire machine--but what is here may be of interest to historians of computer science.

The moment that I saw this image1 of (what I think is) the 8086 processor I thought of its great visual similarities to one of the greatest engineering works of the 16th century, so much so that with a little imagination, the older work seems a pentimento of the newer. This microprocessor--which in 1979 was a vast leap forward in development--looks like an architectural/engineering plan: large objects being hauled into place by legions of workers with wooden cranes, giant winches and mammoth rope, a fantastical display of concerted effort on a gargantuan scale. It is, or was, in fact an enormous leap in hardware engineering, a micro-mammoth advancement.
This older, pentimento image is a plan for moving of the great 500,000-pound Egyptian obelisk (carved during the reign of Nebkaure Amenemhet II, 1992-1985 BCE, and originally standing in the Temple of the Sun at Heliopolis) at the Vatican.
The engraving appearedinDomenico Fontana's masterpiece Della trasporatione dell’obelisco Vaticano…(published in Rome by Bassa in 1590) and illustrated one of the greatest engineering feats of the Renaissance. Moving this enormous and relatively delicate object (from the Circus Nero, where it was placed by the emperor Caligula in 37 ACE, to St. Peter’s Piazza del Popolo, 50 years or so before it would be more enveloped by Bernini’s flying wings) took years of (very) careful planning and months of motion and movement, not to mention an extra month to get everything into place and slowly raise the obelisk into its final position. Fontana had to be cautious and correct, and he was, performing a not-so-minor miracle of pre-industrial magic to move the priceless 250-ton iconic relic and place it perfectly down in the center of Christianity. That must have been one hot Roman summer, especially for Fontana.
I can easily see the similarities in Fontana's work and that of Intel. Here, in a photograph of the 16k bit random access memory chip (via Mostek Corporation) I can see a vast palace at the top of the picture, with a long, columned entrance with manicured gardens on either side. The image offers an elevation and a plan--that is, the top and bottom images of the buildings are seen in a deeply oblique view, while the central part of the image is a straight-out plan. At least that's what I see, its imaginative possibilities more appealing than the physical realities (though that's where the extraordinary value is/was).

Alfred Barlow wrote a splendid history of weaving1 in 1878, and in that book's later pages--and I suspect much overcome with the recent developments in the electrical field (not the least of which were the newly-invented light bulb and telephone)--Mr. Barlow waxes considerably on the application of electricity to the Jacquard process.
He writes,"It is scarcely to be wondered at that men acquainted with the application of electricity to telegraphy and other purposes should have believed it equally serviceable in some of the operations of weaving. As it might be expected, the Jacquard apparatus seemed to offer and excellent opportunity for the needles [reading the holes ion the loom punch cards] to be worked, not by the direct pressure of a card, but by the connecxion of a series of electro-magnets."
Amd then this bombshell: "By this means it was believed that paper may be substituted fir the cards, and the magnets might operate upon the needles through the perforations in the paper, or by passing a current of electricity through the medium of a metallic conducting surface on a sheet of paper or cloth representing the design to be woven, and thereby acting without the use or need of perforations." (Pages 424-5)
It was certainly a capital idea. Barlow may have been referencing the work of Alexander Bain and his punched-tape telegraph of 1841, though he does not mention him specifically. Barlow does mention several inventors from the 1850's who managed to make improvements with electricity in Jacquard-style machines, though none with the great effectiveness which he described here. The real, great advancement in computation waited for quite some time, even beyond the great innovations of Herman Hollerith (who began his tabulating successes in the 1880's, coming into international recognition with his work on the 1890 U.S. Census). But Barlow's imagination here is quite full, and just a little beyond his time.

The document ("Computer Requirements/Statistics Branch/Fort Detrick Maryland") is handwritten by the former chief statistician around 1957, and in five tight pages outlines the basic necessities for the needs of computing facilities at the fort. The document mentions two machines in particular, the "409-2" (with is the Remington Rand 409-2, an ENIAC style machine, produced in 1952) and the UNIVAC 120 (which is a release of the 409-2, done in 1953).
I'm sharing this little stash of computer memorabilia (dated from 1949-1954) because in its age it is so, well, "fresh"and new and uncomplicated--and that's because it was, relative to what we experience now. In 1954 there about 10,000 people working in the field of computing; 61 years later the growth in involvement of people working in the field is perhaps three orders of magnitude--the growth in the sheer volume of printed and digitally-circulated material is probably somewhere on the order of the differences between post-Gutenberg European printing and the printing industry in the year 1990. The changes are spectacular, and they seem to be so much more appreciable when one looks at the foundation efforts from the early years, some of which can be seen and represented in documents like those that follow.
First up is this computer-printed list of attendees for "Dinner Honoring Seminar on Computation, IBM Homestead, December 8, 1949. It is a hand-stapled, four-page list with some big names in the history of computing including Brillouin, Eckert, Grosch, Hamming, Tukey, Yowell, and others.
The next document is the draft consideration for the Constitution of the ACM and is a 3-page cover later dated July 1953 regarding the voting on the new Constitution and also on officers of the ACM. It also details printing costs and distribution of the Proceedings, and other associated housekeeping, including a 3-page offset-printed ballot for voting on the Constitution.
The small $25 miracle/godsend to number crunchers everywhere was this small, nine-place, sliding-digit chain-adder mechanical calculator, set in nickel-plated metal, and which we see in this fantastic and half-bizarre ad in Illustrirte Zeitung for June 1922. The instrument was about eight inches long and came in its owns hard case, and was a very good instrument for the lowish-end market. The add of course is fantastic. ("Die Erloesung" could I guess be transliterated as "Deliverance!" from the drudgery of making calculations by hand.)
Earlier in this blog I posted a magnificent illustration of the fabulous new comptometer adding/calculating machine, here. I wanted to include this unusually designed ad for the machine somewhere on the blog before I lost it (again), and so here it is:
In my experience the use of diagonal black-and-white lines like this for illustration or advertisements was really very uncommon.
The first exposure of the American public in general to a "personal computer" may have been in this issue1 of the Scientific American for November 1950--an article called "Simple Simon" by Edmund Berkeley. ( Berkeley also wrote a book called Giant Brains, which seems to me to be the first mass-consumption book--written in terns for the general public--on how the computer works, and the design of "how a machine will think". Berkeley looks at the MIT Differential Analyzer #2, the Moore School ENIAC, Bell Labs' General-Purpose Relay Calculator, and the IBM Automatic Sequence-Controlled Calculator.)
The Simon was a five-hole paper tape (which was its data entry and memory) 2-bit storage relay-based computer that could use numbers from 0 to 3. It was extremely limited, but it worked, and it was real. And affordable. And a baseline for things to come.
Berkeley introduced the idea for Simon in Giant Brains:
"We shall now consider how we can design a very simple machine that will think.. Let us call it Simon, because of its predecessor, Simple Simon... Simon is so simple and so small in fact that it could be built to fill up less space than a grocery-store box; about four cubic feet....It may seem that a simple model of a mechanical brain like Simon is of no great practical use. On the contrary, Simon has the same use in instruction as a set of simple chemical experiments has: to stimulate thinking and understanding, and to produce training and skill. A training course on mechanical brains could very well include the construction of a simple model mechanical brain, as an exercise..."--Edmund Berkeley, in Giant Brains, 1949, p. 22
In the Scientific American paper Berkeley introduced the machine and how it functioned; he also described three three outcomes for Simon:
First: "Simon itself can grow. It possess all the essentials of a mechanical brain..."
Second: "It is likely to stimulate the building of other small mechanical brains. Perhaps the simplicity and relatively low cost of such machines may make them attractive to amateurs as the radio set and the small telescope." [The "low cost" in 1951 was $600--equal to about $3000 today.]
Third: "It may stimulate thought and discussion on the philosophical and social implications of machines that handle information..."
Berkeley finishes the three-page article with the following paragraph, looking into the not-too-distant future:
"Some day we may even have small computers in our homes, drawing their energy from electric-power lines like refrigerators or radios ... They may recall facts for us that we would have trouble remembering. They may calculate accounts and income taxes. Schoolboys with homework may seek their help. They may even run through and list combinations of possibilities that we need to consider in making important decisions. We may find the future full of mechanical brains working about us."
Scientific American in that same year published another early computer effort of high marks: the great Claude Shannon's "A Chess-Playing Machine." This is the first (and popular) appearance of Shannon's technical paper (which would appear a month later in the Philosophical Magazine), and it is the earliest appearance of an attempt to understand the necessities of a computer for playing a game of chess.
The most influential book in the young life of Alan Turing is said to be What Every Child Should Know Library--it is a six volume work1, and it seems as though the volume of interest was Natural Wonders Edwin Tenney Brewster2 printed in 1912 (and 1927, 1928, and 1939). David Newton3 believes that Turing's fascination with the book was in part due to a statement by Brewster discussing the machine aspects of the human body. Andrew Hodges in his own biography of Turing (Alan Turing, the Enigma) wrote elegantly that the joy in the book was Turing finding that "such a knowledge of 'science' could exist", which is a great and arching statement and also as broad as it was concise, and poetic.
I'm going to side with poetry on this one. And I do so because of the extraordinary structure of the book and its lovely chapter headings, the table of contents as elegant as a poem itself. They are an invitation to wonder, these thoughtfully prodding and engaging statements, and I can easily see how a creative child could react very positively to them.
JF Ptak Science Books Post 2321 A Post called "Computer Art, 1949", revisited and much expanded
This is a great example of an exactly-what-is-this object, something that seems to be one thing, then the other, but then neither.
I'm not sure how to investigate this right off-hand, but I think that there is a special category in the history of art, subcat history of art and technology, subcat history of computer art, subcat using the technical aspects of the computer in art. The image above comes from the front cover of one of the early issues of the "new" Physics Today magazine (volume 2, number 10), in October 1949--it is the artwork of Paul Bond, who created this portrait of a juggler "on a matrix sheet used for plotting computor [sic] plug board diagrams", and is one of 11 such images. So, while not computer art--artwork generated by the computer--it is artwork using items designed to operate the computer, a sort of very early computer-material montage. (It would be in the first-time-ish category, but I can't say this with any surety--it is however very very early for what it is.)
It reminds me in a way of a magazine article using the illustration of a photograph--it was in the curious category of the first time an image of a photograph was published, that is to say it was a woodcut of a photograph though not the photograph itself. This appeared in Golding Bird's series of articles, "A Treatise on Photogenic Drawing", which was five papers found and bound in the London-published journal, The Mirror. and were extremely works on the new science of photography, appearing in issues from April 20-May 25, 1839. The image appears on page 241 (issue no. 945, Saturday April 20) and displays this first image of a photogenic drawing, which was the first publication of an image produced by any sort of photographic process. (The process here is the 'sun picture" , a photographic process, making this the first published "photographic" image, but really it is more like the first publication of a photographic image that was produced via woodcut. It predates the first mass-published photograph by four years and the first (entirely) photographically illustrated book (The Pencil of Nature ) by six years.)
Our computer artwork illustrates an interesting article ("Modern Computing") by pioneers R.D. Richtmyer and N.C. Metropolis . Richtmyer/Metropolis have a very sober approach to the computer--and mostly speaking about the ENIAC--and address its romance, possibilities, and seemingly (to me) most of all "a need for defining the limits of computing machine operation, as well as its promise". In effect, the authors really only address the known quantities of computing capacity in 1949, and even though tempted by looking into the future, they really do not. Their vision of the future is very pragmatic, and so far as speaking to future applications of the machine they choose the very Bartlebian philosophy and chose not to: they conclude "by their very nature, these applications are not easy to foresee, and perhaps, therefore, this is the point at which this discussion should close", preferring to watch the beautiful and complex whirlwind in a thicket from the outside.
There have been much earlier images of automated steam-driven robots with some sort of calculating brain, and images of imaginative computer-like objects, and stretching back into the 18th century, so the idea of creativity and thinking and human-like qualities made by things constructed of metal and wood with a power source of steam or electricity and so on was well-established, though lurking in deep-background. Art made with the computer seems to come a fair bit later than this issue, later still than what might be considered the first art generated via the computer (which were images made from manipulating an oscilloscope) in 1952. This was the work of Ben F. Laposky (1914-2000) an Iowan and mathematician/draftsman and former sign-painter who took long time exposure photographs of waves motions on a cathode ray oscilloscope with sine wave generators and found beauty in them. His work was first exhibited at the Sanford Museum in Cherokee, Iowa, in 1952, as "Oscillons or Electronic Abstractions"1 --hundreds of other shows would follow.2 One of the earliest appearances in print of the oscillons is in Scripta Mathematica, Sept-Dec, 1952, pp 305 (and then somewhat later in Design, May 1953).
Among the earliest computer-generated art--that is, art made via an automatic process input by humans by created by the machine--was created and noted by A. Michael Noll (b. 1939) with an IBM 7094 and described as "computer art" in "an August 1962 technical memorandum"3. Noll has written extensively (and interestingly! and early) on human/computer interfaces including computers and dance, fourth dimensional imaging, and much else4, including a fabulous comparative study of an original Mondrian and a computer-generated alternative5. (Noll is today widely recognized as one of the first in the field of digital art and 3-D animation.)

In any event, I think at the very least that the Bond artwork is very curious, interesting, and probably very early for what it is.

2. "Electronic Abstractions are a new kind of abstract art. They are beautiful design compositions formed by the combination of electrical wave forms as displayed on a cathode-ray oscilloscope. The exhibit consists of 50 photographs of these patterns . A wide variety of shapes and textures is included. The patterns all have an abstract quality, yet retain a geometrical precision . They are related to various mathematical curves, the intricate tracings of the geometric lathes and pendulum patterns, but show possibilities far beyond these sources of design."—Sanford Museum, Gallery notes for Electronic Abstractions, 1952 (Wiki) For a good appreciation of Laposky, see Alison Drain, "Laposky's Lights Make Visual Music" in Symmetry 4/3, pp 32-33.

This is a general report on the origin, development and status of the Hagelin "cryptographers"--a word used here to describe the physical machines (rather than the people working on codes). After his father invested in Aktiebolget Cryptograph, Boris C.W. Hagelin (1892-1983) took over ht leadership of the company in 1925, producing several fine models of encoding crypto machines, using Arthur Scherbius' (as in the "Scherbius Principle", 1878-1929) rotor designs, some of which were marketed under the name "Enigma" (models of which were purchaed by the Wehrmacht in 1926 and modified for heavy use in the '30's and through WWII). The company produced 140,000 units during WWII (while headquartered in the U.S) and is still in business today as Crypto AG, in Zug, Switzerland.
(The Hagelin Cryptographers, an Analysis. Stamped CONFIDENTIAL, mimeographed in New York, by Ericsson Telephone, 1942.)
Sections in the document include "Models Built at Express Demand of the French Authorities", "Evolution of Hand Cryptographer Type C-362", "Hagelin Cryptographer Models" (BC-38 and C-362), "Methods of Operation", "Superiority of Hagelin Cryptographers over Competing Makes", and others, including a final section "How to Sell Cryptographers". There is a mention of the "Enigma" machine on page 14, which is limited to mentioning that it is not sold outside of Germany. Although the Swiss firm founded by Boris Hagelin has manufactured, and continues to manufacture, many kinds of cipher machines, the words "Hagelin machine" will normally inspire thoughts of their unique lug and pin based machines.
