he earliest origins of Lincoln can be traced to the remains of an Iron Age settlement of round wooden dwellings (which were discovered by archaeologists in 1972) that have been dated to the 1st century BC. This settlement was built by a deep pool (the modern Brayford Pool) in the River Witham at the foot of a large hill (on which the Normans later built Lincoln Cathedral and Lincoln Castle) . The origins of the name Lincoln probably come from this period, when the settlement is thought to have been named in the Brythonic language of Iron Age Britain's Celtic inhabitants as Lindon "The Pool"[5], presumably referring to the Brayford Pool. (This early name was subsequently Latinised in the Roman period to Lindum. Later, the designation colonia "settlement, colony" was added — see below — and the combined name Lindum colonia was taken into Old English as something like Lincoln, the modern name of the city.) It is not possible to know how big this original settlement was as its remains are now buried deep beneath the later Roman and medieval ruins, as well as the modern city of Lincoln. [edit] Roman history: Lindum Colonia Newport Arch Newport Arch Main article: Lindum Colonia The Romans conquered this part of Britain in AD 48 and shortly afterwards built a legionary fortress high on a hill overlooking the natural lake formed by the widening of the River Witham (the modern day Brayford Pool) and at the northern end of the Fosse Way Roman road (A46). The Celtic name Lindon was subsequently Latinized to Lindum and given the title Colonia when it was converted into a settlement for army veterans. Lindum Colonia was shortened on the tongues of the later, English speakers, to become 'Lincoln'. The conversion to a colonia was made when the legion moved on to York (Eboracum) in AD 71. Lindum colonia or more fully, Colonia Domitiana Lindensium, after its founder Domitian, was established within the walls of the hilltop fortress with the addition of an extension of about equal area, down the hillside to the waterside below. It became a major flourishing settlement, accessible from the sea both through the River Trent and through the River Witham, and was even the provincial capital of Flavia Caesariensis when the province of Britannia Inferior was subdivided in the early 4th century, but then it and its waterways fell into decline. By the close of the 5th century the city was largely deserted, although some occupation continued under a Praefectus Civitatis, for Saint Paulinus visited a man of this office in Lincoln in AD 629.

History Polyvinyl chloride was accidentally discovered on at least two different occasions in the 19th century, first in 1835 by Henri Victor Regnault and in 1872 by Eugen Baumann. On both occasions, the polymer appeared as a white solid inside flasks of vinyl chloride that had been left exposed to sunlight. In the early 20th century, the Russian chemist Ivan Ostromislensky and Fritz Klatte of the German chemical company Griesheim-Elektron both attempted to use PVC (polyvinyl chloride) in commercial products, but difficulties in processing the rigid, sometimes brittle polymer blocked their efforts. In 1926, Waldo Semon and the B.F. Goodrich Company developed a method to plasticize PVC by blending it with various additives. The result was a more flexible and more easily-processed material that soon achieved widespread commercial use.
