William Murdoch - The "Scottish Edison"
(1754 - 1839)

"Ayrshire Nights Entertainment: A Descriptive Guide to the History,
Traditions, Antiquities of the County of Ayr" by John MacIntosh of Galston,

and Drennan.
William Murdoch was born in 1754 at Bell o' Mill, near Old Cumnock.
His father, who followed the combined avocations of miller, millwright,
and farmer, was
noted as the inventor of toothed circular gearing. While quite a youth,
William's inventive talents began to develop, and he is said to have contrived
a wooden horse
to go by wheels and treadles, on which he and his brother rode to school.
The invention, however, that was to introduce him to the leading mechanics
of the age was an oval lathe. The story of the lathe is this: In the year
1777 Murdoch,
then 23 years of age, set out for England with a view of bettering
his position in life, and finding his way to Birmingham, called at the
Soho Works, then the property
of Messrs Boulton & Watt, the latter of whom afterwards became
famous as the inventor of the steam engine. Mr Boulton was at hand, and
on seeing the raw youth
from Ayrshire, was attracted, curiously enough, not so much by the
young man as by fine hat he wore. "What is that hat of yours made of ?"
enquired the great
engineer. "It is made of wood," was the reply. "And who made it?";
"I made it myself." "And how?" " I turned it on my lathe," was the ready
answer. "What!" asked
Mr. Boulton in surprise, "how is it possible to turn an oval in a lathe?"
" It's quite possible," said the canny Scot, " for I made the lathe myself
that did it. On the merits
of the lathe he was immediately engaged on trial at the salary of 15shillings
per week, and he rose so rapidly to distinction that the great James Watt
began to regard
him as his "right hand man".
Though working for the firm of Boulton & Watt, he resided for the
long period of nineteen years at Redruth in Cornwall. At this place he
was married, and there he
started a foundry of his own. In memory of his stay at Redruth, a tablet
bearing the following inscription, was recently erected in his house in
Cross Street: "William
Murdoch lived in this house 1782 - 1798; made his first locomotive
here; tested it in 1784; invented gas-lighting, and used it in this house
in 1792"
During his stay in Cornwall he was chiefly engaged by the firm in the
erection of engines for the mine-owners of the district, and, as his duties
involved a large amount
of travelling from one place to another, he set himself to improve
upon his youthful idea of the wooden bicycle by constructing one to be
driven by steam. After more
than two years' application to the work he finished a model high pressure,
non-condensing locomotive steam engine, with a copper boiler and fire-box
and flue, a
spirit lamp, one double-action cylinder, two driving wheels and a steering
wheel. This model, exhibited at the great exhibition of 1851, may now be
seen in the
Birmingham Art Gallery. It ran at the rate of from six to eight miles
an hour, and was latterly fitted up with gas. Strangely enough, the man
whose name ultimately
became indissolubly associated with steam and steam engines discouraged
this attempt of Murdoch's, and declared "it would require that God should
work a miracle
to enable steam to move an engine on wheels." It may thus be fairly
allowed that Murdoch is entitled to the credit of being the inventor of
the locomotive, the fruits of
which were reaped by George Stephenson at a later period.
In 1781, Murdoch invented the famous "sun and planet", a device in mechanics
for obtaining circular motion, and also the D slide valve, simplifying
and improving
thereby the construction of steam engines. He also patented a process
for making copperas, vitriol, and different sorts of dye stuffs, paints,
&c., from coal, thus
preluding the introduction of aniline coal tar dyes, which were not
turned to practical account for fifty years afterwards. To shew the fertility
of his inventive mind, it
may be mentioned that he is the inventor of cast-iron cement, of the
oscillating cylinder for marine engines, of a stone-boring machine, and
a direct-acting blast
engine. He also suggested the transmission of letters and packages
through pneumatic tubes, constructed a pneumatic lift, utilized compressed
air to ring the bells in
his own house, and experimented in many other ways with no small degree
of success. As a benefactor of the race, his discovery of the invention
of gas-lighting
entitles him to high honour.
In his first experiments he generated the gas in an iron retort in the
back-court of his house, and conveyed it in a pipe, through a hole in the
frame of the window, to a
point near the ceiling of his room, much in the same way as it is done
still. In 1794, he asked his employers to take out a patent for his invention,
but the firm being
involved in lawsuits over Watt's own patents, declined to take up the
matter. After this Murdoch left the Soho works for a time and started a
foundry on his own
account at Cumnock, a project which he abandoned after a year, and
returned to Watt and Boulton as manager of the firm, at a salary of £1,000
per annum.
Soon after this the firm entered upon the manufacture of gas-making
plant, and the introduction of the new light began gradually to extinguish
the penny candles of the
ancients. After the death of Boulton, Murdoch became a partner in the
Soho concern, and it became under his management one of the greatest engineering
works in
the world. In 1830, he retired from the firm, and nine years later
he died in his eighty-fifth year, and was buried in Handsworth church,
beside his old friends Boulton
and Watt.
