William Aspdin
William Aspdin entered the world on the 23rd of September 1815 in Leeds. He was the second son of Joseph Aspdin, a cement manufacturer who had secured a patent for Portland cement in 1824. This early patent created a fast-setting material used only for mortars and stuccos. William joined his father's firm at age fourteen in 1829. The family business relied heavily on this original formula for decades. A major disagreement between father and son erupted in July 1841. Joseph issued a public notice stating that William was no longer employed by the company. The notice declared that the new firm would not be responsible for any debts William incurred. Joseph also stated that William could not receive money or contract debts on behalf of the partnership. William married Jane Leadman from Barnsley on the 28th of December 1841. No members of either family attended their wedding ceremony.
Aspdin established a manufacturing plant at Rotherhithe in southeast London during 1843. Workers there soon produced a cement that caused a sensation among users in London. He modified his father's formulation by increasing the limestone content significantly. Burning the mixture much hotter yielded a slow-setting product with high strength. This new substance proved suitable for use in concrete construction projects. It was substantially more expensive to produce due to extra fuel costs. Hard clinker required difficult grinding processes that added to expenses. Aspdin did not take out a patent for this discovery. He refused to give it a new name despite its distinct mineralogical properties. Instead he attempted to keep the details of his methods secret. He sometimes claimed the product was covered by his father's existing patent.
William emerged from his office when each newly loaded kiln was ready for firing. He would scatter handfuls of brightly coloured crystals over the raw mix. This act gave the impression that special properties resulted from an unidentified magic ingredient. The goal was to create false impressions of secret ingredients within the process. His rival Isaac Charles Johnson succeeded in creating a similar product for J. B. White & Co.'s nearby Swanscombe plant in 1845. Aspdin never patented his method or disclosed how he achieved these results. Courland documents evidence of both forgery and embezzlement regarding his business practices. One of the most preposterous claims involved Marc Isambard Brunel using his father's cement. William asserted that the older formula helped create the Thames Tunnel in London. Modern analysis shows this claim to be entirely false.
Aspdin contracted several partnerships to finance his operations throughout the 1840s. He acquired the Parker and Wyatt plant at Northfleet creek, Kent under the name Maude, Jones & Aspdin. Manufacturing operations moved there in 1846. He sold out his share of the Northfleet plant in 1852. Financial chaos plagued his career as he went bankrupt at least twice. Angry creditors pursued him at each relocation across England. His history of financial missteps suggests he may have been inept and dishonest. Aspdin made a number of claims which have since been shown to be false. These included trading on his father's name and reputation repeatedly. The courts did not hesitate to identify him as a con man based on available evidence. He faced constant legal pressure from those owed money by his failing businesses.
William set up in Gateshead, County Durham as Aspdin, Ord & Co after leaving Northfleet. In 1857 he sold out again and moved to Germany. From 1860 he established cement plants at Altona and Lagerdorf. These became the first plants to make modern Portland cement outside the UK. G Hägermann documented this expansion in Dokumente zur Entstehungsgeschichte des Portland Zement published in January 1970. He died at Itzehoe near Hamburg on the 11th of April 1864. The Northfleet plant continued making Portland cement on a small scale until taken over by APCM in 1900. The Gateshead plant was bought by I. C. Johnson and operated until 1911. Both sites eventually shut down following acquisition by Blue Circle. William left behind a legacy of innovation mixed with significant controversy regarding his honesty.
