William Congreve
Sir 'William Congreve' was Born
May 20 1772, the son of the Comptroller of the Royal Laboratories at the
Royal Arsenal,
Lt. General Sir William Congreve. He was raised in
Kent,
England, educated at
Singlewell School and educated in law at
Trinity College, Cambridge. He was an
English inventor and
rocket artillery pioneer distinguished for his development and deployment of
Congreve rockets. Congreve died in
Toulouse, France on
May 16,
1828.
Congreve Rockets
After the use of
iron-cased
gunpowder rockets by
Tipu Sultan in
India against British troops during the later
Anglo-Mysore Wars, Congreve was inspired to work on similar devices for use by the British military. The Royal Arsenal's first demonstration of solid fuel rockets was in
1805 when he considered his work sufficiently advanced to engage in two
Royal Navy-run attacks on the French fleet at
Boulogne, France, one that year and one the next. Parliament authorized Congreve to form two rocket companies for the army in
1809. Congreve subsequently commanded one of these at the
Battle of Leipzig in
1813.
Congreve rockets were used for the remainder of the
Napoleonic Wars, as well as the
War of 1812 -- the "rockets' red glare" in the
American national anthem describes their firing at
Fort McHenry during the latter conflict. They remained in the arsenal of the United Kingdom until the 1850s. Congreve was awarded the honorary rank of
Lieutenant colonel in
1811 and was often referred to as "Colonel Congreve."
Other inventions
Besides his rockets, Congreve was a prolific (if indifferently successful)
inventor for the remainder of his life. Congreve invented a
gun-
recoil mounting, a
time-
fuze, a rocket
parachute attachment, a
hydropneumatic canal lock and
sluice (
1813), a
perpetual motion machine, a process of
colour printing (
1821) which was widely used in
Germany, a new form of
steam engine, and a method of consuming
smoke (which was applied at the
Royal Laboratory). He also took out
patents for a
clock in which time was measured by a
ball rolling on an
inclined
plane; for protecting
buildings against
fire; inlaying and combining
metals; un
forgeable
bank note paper; a method of killing
whales by means of rockets; improvements in the manufacture of
gunpowder;
stereotype plates;
fireworks; and
gas meters. Congreve was named as comptroller of the Royal Laboratory at Woolwich from 1814 until his death. (Congreve's father
Sir William Congreve had also held the same post.)
Congreve's unsuccessful perpetual motion scheme involved an endless band which should raise more water by its
capillary action on one side than on the other. He used capillary action of fluids that would disobey the law of never rising above their own level, so to produce a continual ascent and overflow. The device had an inclined plane over
pulleys. At the top and bottom, there travelled an endless band of
sponge, a bed, and, over this, again an endless band of heavy
weights jointed together. The whole stood over the surface of still
water. The capillary action raised the water, whereas the same thing could not happen in the part, since the weights would squeeze the water out. Hence, it was heavier than the other; but as "we know that if it were the same weight, there would be
equilibrium, if the heavy chain be also
uniform". Therefore the extra weight of it would cause the chain to move round in the direction of the arrow, and this would go on, supposedly, continually.
Publications
In 1804 Congreve published ''A concise account of the origin and progress of the rocket system''. Publication of ''A Concise Account of the Origin and Progress of the Rocket System'' by William Congreve was in 1807.
[1] In 1814 Congreve published ''The details of the rocket system''. In 1827 ''The Congreve Rocket System'' was published in London. His other publications were: ''An Elementary Treatise on the Mounting of Naval Ordnance'' (1812); ''A Description of the Hydropneumatical Lock'' (1815); ''A New Principle of Steam-Engine'' (1819); ''Resumption of Cash Payments'' (1819) and ''Systems of Currency'' (1819).
