Editing Halstead (section)

==Evans Electroselenium Ltd==
Arthur Evans was an industrialist, engineer and businessman who began manufacture of selenium photocells in a small workshop in [[Harlow]], Essex, during the Second World War. These were of use in military applications and he was encouraged by the Government of National Unity to find larger premises and rapidly expand the business. He chose Halstead and found a site adjacent to St Andrews Church on Colchester Road. After the war, Evans Electroselenium Ltd (EEL) expanded into all types of scientific instruments which required photocells, including a flame [[photometer]], [[colorimetry|colorimeters]] and [[atomic absorption]] instruments. Later, [[electrochemistry]] instruments were added. The business was eventually bought by [[Corning Inc]] and went through several mergers and acquisitions. Today it is part of [[Siemens Healthineers]] and operates only from the former Corning-EEL site in [[Sudbury, Suffolk]]. The Halstead site was redeveloped for housing as Evans Court in tribute to the founder. The [[Science Museum, London|Science Museum]] in London holds a collection of EEL scientific instruments. Others are held in the Halstead Town Museum collection.
