supply of sulfuric acid and hydrochloric acid; and of coal from the Black Country coal fields. It was also adjacent to two different arms of the Birmingham Canal Navigations, (the BCN), one leading off the Titford Canal, so it had good transport links. Production of the red form of phosphorus, "amorphous phosphorus" was commenced by Arthur Albright in 1851, by heating white phosphorus in a sealed crucible under a vacuum. It had been discovered by Professor Schrötter, in Vienna and patented by him. However, it was explosive to make and Albright discovered a safe means of production. On 31 December 1854 Albright terminated his partnership with the Sturges; and John Edward Wilson, a merchant, joined him. In 1856 John Edward Wilson became a partner, and the new partnership was known as Albright and Wilson. In 1857 John Wilson married the sister of Rachel Albright (Albright's wife). The Sturge Brothers continued as manufacturing chemists at Birmingham, but moved their works to Stirchley; and no longer had any involvement with phosphorus. Oldbury remained the Headquarters of Albright and Wilson for most of the company's existence, eventually becoming known as the Oldbury Division. The Oldbury site was also the location of its central Research Laboratories. The business was so highly regarded in Oldbury that a new secondary school opened in the town in the 1930s was named Albright Secondary Modern School. The firm also maintained a leased London office, at Knightsbridge Green. In October 1974 it moved its Industrial Chemicals Divisional Offices, from Oldbury, to Warley. The six-storey office block, A&W House, at 210–222 Hagley Road, was originally rented for 25 years. Fifteen years later, parts of the Head Office were moved from Knightsbridge Green to A&W House. In October 1991 the Head Office moved to A&W House; and in 1997 the freehold of the building was purchased. A&W House was sold in 2001; and is now known as Quadrant West. Phosphorus and match phosphates In the early days, white phosphorus was obtained from bone ash by treating them with hydrochloric acid to produce precipitated phosphates. Then heating the meta phosphate for several days in a sealed crucible, in a retort, and distilling off phosphorus vapour, under water. Huge quantities of coal were needed for heating these retorts. The production of white phosphorus was improved by using phosphate rock and sulfuric acid instead of bone ash and hydrochloric acid; and by the use
