5. Joseph Marie Jacquard (7 July 1752 – 7
August 1834) was a French weaver and
merchant. He played an important role in
the development of the earliest
programmable loom (the "Jacquard
loom"), which in turn played an important
role in the development of other
programmable machines, such as an
early version of digital compiler used
by IBM to develop the modern
day computer.

6.  Joseph Marie Jacquard was born into a conservative catholic family
in Lyon, France on 7 July 1752. He was one of nine children of Jean
Jacquard, a master weaver of Lyon, and his wife, Antoinette Rive.
 Joseph received no formal schooling and remained illiterate until he
was 13.
 His mother died in 1762, and his father died in 1772.
 Before becoming involved in the weaving of silk, Jacquard was a type-
founder, a soldier, a bleacher of straw hats, and a lime burner etc.
 On 26 July 1778, Joseph married Claudine Boichon. She was a middle-
class widow from Lyon who owned property and had a substantial dowry.
 By 1800, Joseph began inventing various devices. He invented a
treadle loom in 1800, a loom to weave fishing nets in 1803, and starting in
1804, the “Jacquard” loom, which would weave patterned silk
automatically. However, none of his inventions operated well and thus
were unsuccessful.

7.  In 1801, Jacquard exhibited his invention at the industrial exhibition
in Paris. A loom by Jacques de Vaucanson on display there suggested
various improvements in his own, which he gradually perfected to its
final state. Although his invention was fiercely opposed by the silk-
weavers, its advantages secured its general adoption, and by 1812
there were 11,000 Jacquard looms in use in France. This claim has
been challenged: Initially few Jacquard looms were sold because of
problems with the punched card mechanism. Only after 1815 — once
Jean Antoine Breton had solved the problems with the punched card
mechanism — did sales of looms increase. The loom was declared
public property in 1806, and Jacquard was rewarded with a pension
and a royalty on each machine.
 Jacquard died at Oullins, 7 August 1834. Six years later, a statue
was erected to him in Lyon, on the site where he exhibited his loom in
1801.

8. JACQUARD LOOM:-
The Jacquard machine is a device fitted
to a power loom that simplifies the
process of manufacturing textiles with
such complex patterns
as brocade, damask and matelassé. It
was invented by Joseph Marie
Jacquard in 1804. The loom was
controlled by a "chain of cards", a number
of punched cards, laced together into a
continuous sequence. Multiple rows of
holes were punched on each card, with
one complete card corresponding to one
row of the design.

9. Principle of Operation:-
Each position in the card corresponds to a "Bolus" hook,
which can either be raised or stopped dependent on whether
the hole is punched out of the card or the card is solid. The
hook raises or lowers the harness, which carries and guides
the warp thread so that the weft will either lie above or below
it. The sequence of raised and lowered threads is what
creates the pattern. Each hook can be connected to a
number of threads, allowing more than one repeat of a
pattern. A loom with a 400 hook head might have four
threads connected to each hook, resulting in a fabric that is
1600 warp ends wide with four repeats of the weave going
across.

10. This portrait of Jacquard was
woven in silk on a Jacquard
loom and required 24,000
punched cards to create (1839).
It was only produced to
order. Charles Babbage owned
one of these portraits; it inspired
him in using perforated cards in
his analytical engine. It is in the
collection of the Science
Museum in London, England.

11. The Jacquard head used replaceable punched cards to control a
sequence of operations. It is considered an important step in the history
of computing hardware. The ability to change the pattern of the loom's
weave by simply changing cards was an important conceptual precursor
to the development of computer programming and data entry. Charles
Babbage knew of Jacquard looms and planned to use cards to store
programs in his Analytical engine. In the late 19th century, Herman
Hollerith took the idea of using punched cards to store information a
step further when he created a punched card tabulating machine which
he used to input data for the 1890 U.S. Census.
Some early computers, such as the 1944 IBM Automatic Sequence
Controlled Calculator (Harvard Mark I) received program instructions
from a paper tape punched with holes, similar to Jacquard's string of
cards. Later computers executed programs from higher-speed memory,
though cards were commonly used to load the programs into memory.
Punched cards remained in use in computing up until the mid 1980s.
