George
Stephenson
(1781-1848)
George Stephenson was born on 9th June 1781at Wylam near Newcastle-upon-Tyne.
His connection with Manchester lies in his design and construction
of the railway sheds at Victoria Station in the city centre.
He grew up with a keen interest in machines and as a young man
he attended evening classes in reading and writing. In 1802 he
became a colliery engineman and married Frances Henderson. He
also did clock repairs to supplement their meagre income. In 1803,
his son Robert was born. In 1806 his wife, who had long suffered
with ill health, died of tubercolosis.
George developed an increasing interest in engines of all types;
he frequently dismantled them in order to better understand their
function and construction and by 1812 his wide practical knowledge
of engines resulted in him being employed as a colliery enginewright.
Gradually he became preoccupied with developing a locomotive;
he convinced the pit manager to allow him to work on a steam-powered
machine, and by 1814 he had constructed an early locomotive capable
of hauling thirty tons up hill at a speed of 4 mph. Over the next
five years Stephenson went on to build some sixteen engines, so
that the colliery owners were gave him the task of building a
eight mile railroad from Hetton to the River Wear at Sunderland.
In April 1821 an Act of Parliament was passed enabling one Edward
Pearse to build a "horse railway" that would link the collieries
in West Durham, Darlington and the River Tees at Stockton. Stephenson
arranged a meeting with Pease and suggested that he should consider
building a locomotive railway, and that he was the very man to
do it. Stephenson's engine, the "Blutcher", so impressed
Pearce that he offered him the post as the chief engineer of his
Stockton & Darlington company. Stephenson immediately began working
to develop iron rails at William Losh's ironworks in Newcastle.
By 1823 Pease joined one Michael Longdridge, George Stephenson
himself and his son Robert to form Robert Stephenson & Company
at Forth Street in Newcastle to become the world's first locomotive
builders. In 1822 they began work on a 15 mile track from Stockton
to Darlington. The opening of the Stockton & Darlington line on
27th September 1825, was attended by large crowds as the engine
"Locomotion" pulled 36 fully laden wagons a distance of nearly
9 miles in two hours, at times achieving speeds of 15 mph. Following
on this success, Stephenson went on to become engineer at the
Bolton & Leigh Railway, as well as chief engineer of the proposed
Liverpool & Manchester Railway (the LMR). A competition was held
to choose a suitable locomotive to work on the LMR; the winning
locomotive would be awarded £500. The competition was held at
Rainhill during October 1829 and 10 locomotives originally entered
the Rainhill Trials. However, only five turned up and two were
withdrawn with mechanical problems. In the end it was between
the "Sans Pariel", "Novelty" and the Stephenson's "Rocket" developed
by George and his son, Robert. The Rocket beat both competitors,
and the rest, as they say, is history.
The Liverpool & Manchester Railway opened on 15th September 1830,
with the prime minister, the Duke of Wellington, and many civic
dignitaries in attendance. Disaster struck as a the government
minister, William Huskisson was knocked down and killed by one
of the locomotives - the first railway fatality. However, the
success of Stephenson's engines was secure, and he went on to
be chief engineer for many other railway companies, including
the Manchester & Leeds, Birmingham & Derby, Normanton & York and
Sheffied & Rotherham. He was also responsible, along with his
son Robert, for the design and construction of the railway platform
sheds at Manchester Victoria Station.
George Stephenson continued to work on improving the quality of
the locomotives and later moved to live in Chesterfield where,
with a partner, he opened coalmines, ironworks and limestone quarries
in the area. He also owned a small farm where he experimented
in stock breeding and developing new animal foods. George Stephenson
died at Tapton House, Chesterfield on 12th August 1848.

Thomas Earnshaw |
Thomas
Earnshaw
(1749-1829)
Thomas Earnshaw was a pioneer horologist and one of several developers
of the marine chronometer. He was born in Mottram, Ashton-under-Lyne,
Lancashire, (now in the Metropolitan Borough of Tameside). Though
his youth was spent in Lancashire, he spent most of his productive
adult life working in premises at 119 High Holborn in London,
where he lived and raised his family.
In 1782 he invented the so-called spring detent chronometer escapement,
(also known as the chronometer escapement), which was to
become the standard for marine chronometers throughout the 19th
century and essentially remained unchanged to the present day.
It has only been superseded in quite recent times by quartz digital
timepieces. Earnshaw's detent escapement revolutionised portable
time-telling at sea.
His work paralleled that of his rival, John Arnold, another celebrated
London watchmaker. However, it was Earnshaw who had simplified
the design of the pocket and marine chronometers into their modern,
readily reproducible form. Both Arnold and Earnshaw had produced
chronometers for £60 and these had become commonplace by
the 1820s.
Initially, Earnshaw did not hold the patent to his invention -
this was owned by Thomas Wright because Earnshaw was unable to
afford the cost of registration.
Two Earnshaw chronometers can be found at the Royal Observatory,
placed there at the request of the Astronomer Royal, Nevil Maskelyne,
(another rival). Earnshaw's so-called No.1 chronometer had been
delivered for trials at the Royal Greenwich Observatory in February
1792, where it remained for two years until it was finally installed
by Earnshaw himself at Armagh in Northern Ireland on the 18th
August 1794, (where it remains to this day).
There were rival claims as to the origination of his timepieces,
and Earnshaw fought both of his horological rivals for more than
a decade, as well as taking on the government in order to secure
fair recognition and reward for his endeavours.
His mechanism differed from its predecessors in that it gave impulse
to the balance in one direction during a short section of its
arc, and had the advantage over Arnold's type in not requiring
oil on the escape wheel teeth.
Disillusioned, Earnshaw even published an article, "Appeal
to the Public" in 1808, in which he presented the evidence
of his invention, but even this failed to gain the recognition
he deserved.
Eventually, recognition and remuneration did come, so that in
1853 Thomas Robinson, another celebrated clock maker, wrote of
Earnshaw's clock that it was "…probably the best in
the world".
Eventually, Earnshaw's spring detent escapement was awarded £3,000
from the Board of Longitude for its contribution towards the solution
of the longitude at sea problem, and nowadays Thomas Earnshaw
ranks amongst our greatest chronometer inventors and has finally
secured his rightful place in the history of marine technology.
He died in 1829 in London, and his old premises in High Holborn
carries a Blue Plaque to mark his achievement.

Sir
Roger Bradshaigh
An antiquarian
called John Leland, in his 1540 "Itinerary", wrote:
'Mr Bradshau
(Bradshaw or Bradshaigh) hath a place callid Hawe (or Haigh)
a myle from Wigan. He hath found moche canel ... in his grounde
... very profitable to hym'.
The 'canel'
in question was the famous Haigh Cannel - the name probably derived
from 'candle' - a locally mined mineral which was an excellent
light fuel which burned with a bright flame, was easily lit and
left virtually no ash. The material was smooth, hard, and could
be worked and carved, by hand or turned on a lathe, and made into
ornaments. Its development as a material came into its own in
the early 19th Century, where its high illuminating power was
ideal for the crude domestic burners of the day, before the incandescent
gas mantle was available.
In the 16th century, Sir Roger Bradshaigh had discovered this
plentiful seam of Cannel on his estate at Haigh near Wigan. Further,
it was in a shallow depth seam just a few feet from the surface.
The deposit came to be known as "the Great Haigh Fault" and runs
alongside the the Leeds & Liverpool Canal. The shallow depth of
the Cannel meant that it was suitable for the simple surface mining
methods available at that time. It was widely used for domestic
lighting throughout the region and gradually lost favour as the
increasingly widespread use of coal gas made it obsolete.

James Hargreaves

James Hargreaves
(c.1720-1778)
James Hargreaves was born sometime around 1720 in Blackburn Lancashire.
He was largely uneducated and illiterate, and worked as a carpenter
and weaver for many years during his early life. At that time,
spinning and weaving was predominantly a small cottage industry.
Most people worked as farming communities, but kept small spinning
wheels and looms at home where they worked in the evening to add
to their meagre income. Hargreaves' invention of the Spinning
Jenny was to change all that, and would be a crucial implement
in the advancement of the Industrial revolution.
In the 1760s Hargreaves lived at Stanhill where he would develop
the concept of a whole line of spindles working off one single
wheel. By 1764 he had built a prototype machine, all hand engineered
and crafted - it would become known as the 'Spinning Jenny'. It
utilised eight spindles turned by a single wheel - spinning eight
threads at once for the same effort and in the same time that
conventional spinning could only manage one thread.
Hargreaves' invention had only ever been intended for personal
use in his home, of course, but soon others wanted to buy his
machine, and their manufacture soon began to take off as a fully
commercial enterprise. Traditional Lancashire spinners, however,
fearing being made redundant and unable to compete with the cheaper
manufacturing costs that the Jenny made possible, actually broke
into his house and destroyed his equipment.
Hargreaves had very little business sense and by the time that
he finally got round to applying for a patent on his invention
in 1770, many others had already copied the concept and consequently
Hargreaves made little or nothing from his invention. In fact,
harassed by threats, he moved away to Nottingham and set up his
own spinning mill.
Over time, improvements to his Jenny resulted in its capacity
being increased from eight to eighty threads. When he died in
1778, it is estimated that over 20,000 of Hargreaves' Spinning
Jenny machines existed in the United Kingdom, though Hargreaves
himself died in abject poverty, having failed to capitalise on
such a brilliant and revolutionary idea.
