==Description==
"1872 William Stevens Squire (1834–1906) of Dunn, Squire and Co, initially at Stratford in Essex, formed the company Squire, Chapman & Co. with Mr Spencer Chapman, premises at North Woolwich Rd, Silvertown, as makers of sulphuric acid[1]. Squire took his assistant Rudolph Messel with him to the new business.
Messel developed a process for the manufacture of fuming sulphuric acid, which was in great demand as a raw material in the dyestuffs industry. The key to the process was the combination of pure sulphur dioxide and oxygen gases using a platinized pumice catalyst. The process was patented by Squire in 1875." http://www.gracesguide.co.uk/Spencer_Chapman_and_Messel 

I can't really find any information on when they stopped manufacturing at this location. According to the Times, after the merger sometime in 1964-1966 to form Berk Spencer Acids, a new works was going to be built at Stratford. http://find.galegroup.com/ttda/infomark.do?&source=gale&prodId=TTDA&userGroupName=usaskmain&tabID=T003&docPage=article&searchType=BasicSearchForm&docId=CS369583759&type=multipage&contentSet=LTO&version=1.0
