HENRY See also:PERKIN (1838-1907)
, See also:English chemist, was See also:born in See also:London on the 12th of See also:March 1838
.
From an See also:early See also:age he determined to adopt See also:chemistry as his profession, although his See also:father, who was a builder, would have preferred him to be an architect
.
Attending the See also:City of London School he devoted all his spare See also:- TIME (0. Eng. Lima, cf. Icel. timi, Swed. timme, hour, Dan. time; from the root also seen in " tide," properly the time of between the flow and ebb of the sea, cf. O. Eng. getidan, to happen, " even-tide," &c.; it is not directly related to Lat. tempus)

time to chemistry, and on leaving, in 18J3, entered the Royal See also:College of Chemistry, then under the direction of A

W
.
See also:Hofmann, in whose own See also:research laboratory he was in the course of a See also:year or two promoted to be an assistant
.
Devoting his evenings to private investigations in a rough laboratory fitted up at his See also:home, See also:Perkin was fired by some remarks of Hofmann's to undertake the artificial See also:production of See also:quinine
.
In this See also:attempt he was unsuccessful, but the observations he made in the course of his experiments induced him, early in 1856, to try the effect of treating See also:aniline sulphate with bichromate of potash
.
The result was a precipitate, aniline See also:black, from which he obtained the colouring See also:matter subsequently known as aniline See also:blue or See also:mauve
.
He lost no time in bringing this substance before the managers of Pullar's dye-See also:works, See also:Perth, and they expressed a favourable See also:opinion of it, if only it should not prove too expensive in use
.
Thus encouraged, he took out a patent for his See also:process, and leaving the College of Chemistry, a boy of eighteen, he proceeded, with the aid of his father and See also:brother, to erect works at Greenford See also:Green, near See also:Harrow, for the manufacture of the newly discovered colouring matter, and by the end of 1857 the works were in operation
.
That date may therefore be reckoned as that of the See also:foundation of the See also:coal-See also:tar See also:colour See also:industry, which has since attained such important dimensions—in See also:Germany, however, rather than in See also:England, the See also:country where it originated
.
Perkin also had a large See also:share in the introduction of artificial See also:alizarin (q.v.), the red dye of the See also:madder See also:root

See also:Liebermann in 1868 pre-pared that substance synthetically from See also:anthracene, but their process was not practicable on a large See also:scale, and it was See also:left to him to patent a method that was commercially valuable
.
Thishe did in 1869, thus securing for the Greenford Green works a See also:monopoly of alizarin manufacture for several years
.
About the same time he also carried out a See also:series of investigations into kindred substances, such as anthrapurpurin
.
About 1894 he abandoned the manufacture of coal-tar See also:colours and devoted himself exclusively to research in pure chemistry, and among the discoveries he made in this See also:- FIELD (a word common to many West German languages, cf. Ger. Feld, Dutch veld, possibly cognate with O.E. f olde, the earth, and ultimately with root of the Gr. irAaror, broad)

- FIELD, WILLIAM VENTRIS FIELD, BARON (1813-1907)
field was that of the reaction known by his name, depending on the condensation of See also:aldehydes with fatty acids (see CINNAMIC See also:ACID)
.
Later still he engaged in the study of the relations between chemical constitution and rotation of the See also:plane of polarization in a magnetic field, and enunciated a See also:law expressing the variation of such rotation in bodies belonging to homologous series
.
For this See also:work he was in 1889 awarded a See also:Davy See also:medal by the Royal Society, which ten years previously had bestowed upon him a Royal medal in recognition of his investigations in the coal-tar colours
.
The Chemical Society, of which the became secretary in 1869 and See also:president in 1883, presented him with its Longstaff medal in 1889, and in 1890 he received the See also:Albert medal of the Society of Arts
.
In 1906 an See also:international celebration of the fiftieth anniversary of his invention of mauve was held in London, and in the same year he was made a See also:knight
.
He died near Harrow on the 14th of See also:July 1907
