Charles LapworthFRSFGS was an English geologist who pioneered faunal analysis using index fossils and identified the Ordovician period.
Biography
Charles Lapworth was born at Faringdon in Berkshire the son of James Lapworth. He was trained as a teacher at the Culham Diocesan Training College near Abingdon, Oxfordshire. He moved to the Scottish border region, where he investigated the previously little-known fossil fauna of the area. There in 1869 he married Janet, daughter of Galashiels schoolmaster Walter Sanderson and stayed in the area. Eventually, through patient mapping and innovative use of index fossil analysis, based on a sequence exposed at Dob's Linn, Lapworth showed that what was thought to be a thick sequence of Silurian rocks was in fact a much thinner series of rocks repeated by faulting and folding. He completed this pioneering research in the Southern Uplands while employed as a schoolmaster for 11 years at the Episcopal Church school, Galashiels. He then studied geology and became in 1875 an assistant at Madras College in St Andrews, Fife, and then in 1881 the first professor of geology at Mason Science College, later the University of Birmingham, where he taught until his retirement. He is best known for pioneering faunal analysis of Silurian beds by means of index fossils, especially graptolites, and his proposal that the beds between the Cambrian beds of north Wales and the Silurian beds of South Wales should be assigned to a new geological period: the Ordovician. This proposal resolved a long running controversy which began when Roderick Murchison and Adam Sedgwick argued over the relative ages of the strata in question. Lapworth received numerous awards for his research work, while for teaching he used the English Midlands as a setting for demonstrating the fieldwork techniques he had pioneered in his own research. Following his researches in the Southern Uplands Charles Lapworth also devoted time to mapping near Durness in Scotland's northwest highlands and was first to propose the controversial theory that here older rocks were found lying above younger, suggesting complex folding or faulting as a cause. Later Peach and Horne were dispatched to the area and their monumental memoir proved Lapworth correct. In the English Midlands his research involved important work in Shropshire and the demonstration that Cambrian rocks underlay the Carboniferous rocks between Nuneaton and Atherstone. He died on 13 March 1920 and is buried in Lodge Hill Cemetery near Birmingham.
Family
He married Janet Sanderson in 1869. His son Arthur Lapworth became a renowned chemist and his son Herbert a civil engineer, engineering geologist, stratigrapher and palaeontologist.
Papers relating to Charles Lapworth can be found at the University of Birmingham Special Collections. The University of Birmingham also maintains the Lapworth Museum of Geology within the Aston Webb building on the main Edgbaston campus. The Lapworth Archive, housed in the museum, contains a remarkably complete record of all areas of his research work and teaching.
