Birth of Geologist Richard Dixon Oldham

richard-dixon-oldhamRichard Dixon Oldham, British geologist who makes the first clear identification of the separate arrivals of P-waves, S-waves and surface waves on seismograms and the first clear evidence that the Earth has a central core, is born in Dublin on July 31, 1858.

Born to Thomas Oldham, a Fellow of the Royal Society and a geologist, Oldham is educated at Rugby School and the Royal School of Mines.

In 1879 Oldham becomes an assistant-superintendent with the Geological Survey of India (GSI), working in the Himalayas. He writes about 40 publications for the Survey on geological subjects including hot springs, the geology of the Son Valley and the structure of the Himalayas and the Indo-Gangetic plain. His most famous work is in seismology. His report on the 1897 Assam earthquake goes far beyond reports of previous earthquakes. It includes a description of the Chedrang fault, with uplift up to 35 feet and reported accelerations of the ground that have exceeded the Earth’s gravitational acceleration. His most important contribution to seismology is the first clear identification of the separate arrivals of P-waves, S-waves and surface waves on seismograms. Since these observations agree with theory for elastic waves, they show that the Earth can be treated as elastic in studies of seismic waves.

In 1903, Oldham resigns from the GSI due to ill health and returns to the United Kingdom, living in Kew and various parts of Wales. In 1906 he writes a paper analyzing seismic arrival times of various recorded earthquakes. He concludes that the earth has a core and estimates its radius to be less than 0.4 times the radius of the Earth.

In 1908 Oldham is awarded the Lyell Medal, in 1911 made a Fellow of the Royal Society and from 1920 to 1922 serves as the President of the Geological Society of London.

Richard Dixon Oldham dies at Llandrindod Wells in Wales on July 15, 1936.

In 1956, the Earl of Antrim invites Brett to join the Northern Ireland Committee of the National Trust. On finding there are no books written to prepare himself for this, he resolves to write the necessary volumes. In 1957 he becomes the first chairman of the Ulster Architectural Heritage Society, founded alongside, amongst others Lady Dunleath. Brett serves as chairman for ten years and then as President from 1979 until his death.

With the National Trust he puts his legal skill to use in order to establish a public footpath along the cliffs of the North Coast of Ulster. He also sits on the board of the Irish Architectural Archive in Dublin.

In 1971, he is appointed to the board of the newly created Northern Ireland Housing Executive. He serves as Chairman for five years from 1979, during which time 50,000 dwellings are built. He is asked to compile a list of historic buildings in Jersey in 1975. In 1986, Brett becomes the first chairman of the International Fund for Ireland, established to encourage investment in Ireland.

Brett is also involved in Northern Irish politics, being chairman of the Northern Ireland Labour Party for a time. In 1981 he receives a CBE, this is followed by a Knighthood in 1990.

Brett dies on December 19, 2005. His church memorial is located along those of his family in the Comber Church of Ireland Parish Church of St. Mary, in Comber, North County Down.
