1. MEN BEHIND THE COMPUTER

2. THE FATHER OF COMPUTER
CHARLES BABBAGE (1791 – 1871)
 In 1812 or 1813 he made a small calculator that
could perform certain mathematical computations to
eight decimals.
 During the mid-1830s Babbage developed plans for
the Analytical Engine, the forerunner of the
modern digital computer.
 In 1843 Babbage’s friend mathematician Ada
Lovelace translated a French paper about the
Analytical Engine and, in her own annotations,
published how it could perform a sequence of
calculations, the first computer program.
 Babbage’s design was forgotten until his
unpublished notebooks were discovered in 1937

3. The Difference Engine.
The completed portion of Charles Babbage's Difference Engine,
1832. This advanced calculator was intended to produce
logarithm tables used in navigation. The value of numbers was
represented by the positions of the toothed wheels marked with
decimal numbers.

4. FATHER OF MOODERN TECHNOLOGY
ALAN TURING (1912 – 1954)
 British mathematician and logician, who made major
contributions to mathematics, cryptanalysis, logic,
philosophy, and mathematical biology and also to the new
areas later named computer science, cognitive science,
artificial intelligence, and artificial life.
 In 1936 Turing and Church independently showed that, in
general, the Entscheidungsproblem problem has no
resolution, proving that no consistent formal system of
arithmetic has an effective decision method.
 In 1942 Turing also devised the first systematic method
for breaking messages encrypted by the sophisticated
German cipher machine that the British called “Tunny.”

5. TURING THE GENIUS
 In 1945, the war over,
Turing was recruited
to the National
Physical Laboratory
(NPL) in London to
create an electronic
computer. His design
for the Automatic
Computing Engine (ACE)
was the first complete
specification of an
electronic stored-
program all-purpose
digital computer.
 Turing was a founding
father of artificial
intelligence and of
modern cognitive
science. Turing
proposed what
subsequently became
known as the Turing
test as a criterion
for whether an
artificial computer
is thinking (1950).

6. THE TURING MACHINE
 A Turing machine is a mathematical model of
computation that defines an abstract machine, which
manipulates symbols on a strip of tape according to
a table of rules.
 Invented in 1936 by Alan Turing, who called it an
a-machine. With this model, Turing was able to
answer two questions in the negative: Does a
machine exist that can determine whether any
arbitrary machine on its tape is "circular";
similarly, does a machine exist that can determine
whether any arbitrary machine on its tape ever
prints a given symbol. Thus by providing a
mathematical description of a very simple device
capable of arbitrary computations, he was able to
prove properties of computation in general—and in
particular, the uncomputability of the
Entscheidungsproblem ("decision problem").

7. PIONEER OF PARALLEL PROCESSING COMPUTERS
DANNY HILLIS (1956 – still alive)
 Is an American inventor, entrepreneur, scientist, and
writer who is particularly known for his work in
computer science.
 Hillis has founded a number of creative technology
companies, most notable Thinking Machines Corporation,
Applied Minds, Metaweb Technologies, Applied
Proteomics,[18] and Applied Invention.
 Hillis is the recipient of numerous awards, including
the inaugural Dan David Prize for shaping and enriching
society and public life in 2002, the 1991 Spirit of
American Creativity Award for his inventions, the 1989
Grace Murray Hopper Award for his contributions to
computer science, and the 1988 Ramanujan Award for his
work in applied mathematics.

8. THE TINKERTOY MACHINE
MADE ENTIRELY OUT OF TINKERTOYS A GIFT FROM DANNY HILLIS TO GRODEN BELL
IN MAY 18, 1981. “The machine plays tic-tac-toe with the human player
giving the first move. It never loses. The game tree was generated by a
LISP program running on a PDP-10. The PDP-10 also computed the
connections of the 140 nine-input gates in the machine. The gates are
all TTL (Tinker Toy Logic). A simple three-state logic is used to
represent the three possible states of a square (X-O-blank).” DANNY
HILLIS.

9. THE MOUSE MAN
DOUGLAS ENGELBART (1925 – 2013)
 a pioneer in the design of interactive
computer environments best known for inventing
the computer mouse in 1964.
 In the early 1960s, Engelbart founded SRI
International's Augmentation Research Center
in Palo Alto in an effort to further research
information processing and computer-sharing
tools and methods.
 Engelbart designed and was the primary
developer of the oN-Line System, also known as
NLS, a revolutionary computer-sharing system.
 In 1964, Engelbart conceptualized and created
the first design for the computer mouse.

10. The mouse was just a tiny piece of a much
larger project, started in 1962, aimed at
augmenting human intellect (see a 1968
paper for the project).. There were
several devices then in use, or being
considered for use: the light pen,
joysticks, etc. The authors however were
looking for the best and the most
efficient device.

11. At the time of the invention of the
mouse, Engelbart had already been
exploring possible ways for people
to increase their capability to
solve complex problems for almost a
dozen years. Engelbart and William
(Bill) English (a colleague of
Engelbart and the maker of the
mouse) envisioned problem-solvers
using computer-aided working
stations to augment their efforts.
They required the ability to
interact with information displays
using some sort of device to move a
cursor around the screen

12. YVES BEHAR (1967)
 Swiss-born industrial designer and founder of
design and branding firm Fuseproject.
 Some of his works were put on display in museums
modern art, including his original Jawbone
headset for mobile devices where he was chief
designer and his Teflon-coated water-repellant
cashmere windbreaker
 In 2012 SodaStream International teamed with
to introduce Source, a new home soda machine
designed with a special emphasis on
 In June 2012, Yves Behar and Ouya partnered to
create an open, hackable game platform.
FUSION MAN

13. Béhar’s design for the XO-3 tablet, a rugged energy-
efficient sub-$100 computer, it did boast 512 megabytes of
RAM, a Wi-Fi antenna, a peel-off silicone protective
covering, and an optional solar panel for recharging in
sunlight—features that significantly improved its
durability and utility. The XO-3 was the successor of the
original, award-winning XO laptop, the cover of which
Béhar had also designed.
