Naming of Seismometers
One of the seismometers was christened "Allód" an ancient name of the Irish God of the sea. Allód was a winning entry in the seismometer naming competition, suggested by Coláiste Phobail Cholmicille in Donegal.

In 1950, Prof Leo W. Pollak, Director of the School of Cosmic Physics gave a public lecture in UCD, entitled ‘Is the Earth Getting Warmer?’
He outlined early evidence of a changing climate, from the effects of warming latitudes on fish migration, to glacier decay, and noted the growing scientific consensus that global warming was underway.

The ADH Telescope operated in South Africa until 1980.
Though the working life of the ADH telescope is now over, its memory remains. It made significant contributions to Southern Hemisphere astronomy, in particular to studies of the Magenellic Clouds, Galactic Structure and southern Milky Way. Today original pieces of the telescope, as well as original photographic plates are on display at DIAS Dunsink Observatory.

The ADH telescope was used to study faint stars in the Magenellic Cloud & Orion Nebula, as well as search for evidence of a black hole in the centre of our galaxy using early electronic detectors.

The ADH was the brainchild of Harvard Observatory Director, Harlow Shapley who fortuitously met Taoiseach Eamon de Valera at Shannon Airport in 1948, whilst marooned due to fog. Shapley introduced himself and proceeded to discuss ideas for the reopening of Dunsink and the joint telescope project with Harvard and Armagh Observatory.

The ADH Telescope
In 1950 the ADH Telescope was installed in Boyden Observatory in Bloemfontein, South Africa. It was the largest Schmidt telescope in the Southern Hemisphere in the 1950s. The 36 inch Schmidt telescope was built by the Perkin-Elmer Corporation in the US, financed by a £5,000 grant from each Armagh, Dunsink and Harvard

The Armagh-Dunsink-Harvard Agreement
In 1948 DIAS Dunsink was central to the first ever inter-governmental agreement between the two parts of Ireland, and the first international agreement to operate a shared observing facility in the southern hemisphere. This pioneering collaboration linked Armagh and Dunsink Observatory with Harvard University under an agreement to build and operate a large Schmidt telescope at the Boyden Observatory in South Africa.

In 1960, John L. Synge, Senior Professor at the DIAS School of Theoretical Physics, published ‘Relativity: The General Theory’, a seminal text that became a standard reference on Einstein’s theory. Renowned for its clarity and depth, the book shaped international research and teaching, reaffirming DIAS as a leading world centre for research in general relativity.

Through its early international collaborations, DIAS strengthened Ireland’s academic standing by introducing expertise and methods that would have taken fair longer to develop domestically alone. The following slides highlight some of DIAS' collaborations in France, Italy, Austria and Sweden.
