the well-known firm of Messrs.
Siemens Brothers, and was recently transformed into a limited liability
company.
In 1859 William Siemens became a naturalised Englishman, and from this
time forward took an active part in the progress of English engineering
and telegraphy. He devoted a great part of his time to electrical
invention and research; and the number of telegraph apparatus of all
sorts--telegraph cables, land lines, and their accessories--which have
emanated from the Siemens Telegraph Works has been remarkable. The
engineers of this firm have been pioneers of the electric telegraph in
every quarter of the globe, both by land and sea. The most important
aerial line erected by the firm was the Indo-European telegraph line,
through Prussia, Russia, and Persia, to India. The North China cable,
the Platino-Brazileira, and the Direct United States cable, were laid
by the firm, the latter in 1874-5 So also was the French Atlantic cable,
and the two Jay Could Atlantic cables. At the time of his death the
manufacture and laying of the Bennett-Mackay Atlantic cables was in
progress at the company's works, Charlton. Some idea of the extent of
this manufactory may be gathered from the fact that it gives employment
to some 2,000 men. All branches of electrical work are followed out
in its various departments, including the construction of dynamos and
electric lamps.
On July 23, 1859, Siemens was married at St. James's, Paddington, to
Anne, the youngest daughter of Mr. Joseph Gordon, Writer to the Signet,
Edinburgh, and brother to Mr. Lewis Gordon, Professor of Engineering in
the University of Glasgow, He used to say that on March 19 of that year
he took oath and allegiance to two ladies in one day--to the Queen and
his betrothed. The marriage was a thoroughly happy one.
Although much engaged in the advancement of telegraphy, he was also
occupied with his favourite idea of regeneration. The regenerative
gas furnace, originally invented in 1848 by his brother Friedrich,
was perfected and introduced by him during many succeeding years.
The difficulties overcome in the development of this invention were
enormous, but the final triumph was complete.
The principle of this furnace consists in utilising the heat of the
products of combustion to warm up the gaseous fuel and air which
enters the furnace. This is done by making these products pass through
brickwork chambers which absorb their heat and communicate it to the gas
