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 gloabl warming was underway. Prof.Pollak even suggested that Irish coastal towns such as Glengariff in West Cork, or Skerries in Dublin might one day replace the seaside resorts of Southern France!

In 1950, Prof. Leo W. Pollak (Director of the School of Cosmic Physics) asked: “Is the Earth Getting Warmer?”
He pointed to early climate evidence—shifting fish, melting glaciers—and a growing consensus on global warming.

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.

Image 1. Once complete the ADH Telescope was installed in Boyden Observatory in Bloemfontein, South Africa in 1950. It was the largest Schmidt telescope in the Southern Hemisphere in the 1950s.
The 36 inch Schmidt telescope was financed by a £5,000 grant from each Armagh, Dunsink and Harvard, and was built by the Perkin-Elmer Corporation in the US.

No. 5 Merrion Square was personally selected by Taoiseach Éamon de Valera as the premises for the School of Cosmic Physics. The building had previously been owned by Dr Robert Farnan, a Dáil Deputy and family friend. Apparently the house had been a refuge for de Valera on a number of occasions when he was on the run during the War of Independence. No.5 now houses the Geophysics section of DIAS.
Receipt for the purchase of No. 5 by Dr. Robert Farnan from Lady Stokes in 1903 for £2,400. His son Patrick Farnan gifted the receipt of purchase to the DIAS archive in 2015.

In 1949 after years of painstaking restoration to the buildings, re-cataloguing of the library and an overhaul of out of date equipment, Hermann Brück head of the Astronomy section instituted monthly ‘open days’ whereby the public could visit the Observatory. The first official visitor was Éamon de Valera in January 1949, who was delighted that his cherished project of rehabilitating the observatory was a success.
Since its doors first opened to the public in the 1800’s, Dunsink Observatory has welcomed curious stargazers and continuously sought avenues for public outreach. That tradition continues under DIAS with our visitor nights. The public is welcomed to tour the main building and dome, as well as enjoy talks, demos, and weather-permitting stargazing through the historic Grubb telescope (pictured). Keep an eye out for tickets going live on the DIAS Dunsink Eventbrite page!

Dunsink Observatory was built in 1785, and is considered Ireland’s oldest scientific institution. In 1947 the DIAS Astronomy & Astrophysics section became the caretakers of Dunsink Observatory. Today Dunsink Observatory stands as a physical testament to the evolution of astronomical research and education in Ireland and across the world over more than two centuries. In 2018 Dunsink was designated by the European Physical Society as a “site of historical significance”- the first such designation in Ireland and in 2025 as part of the Astronomical Observatories of Ireland, Dunsink Observatory was added to Ireland’s tentative list for Inscription as a UNESCO World Heritage Site.

Leo W. Pollak First Head of Geophysics Section in the School of Cosmic Physics The School of Cosmic Physics comprises two main disciplines: Geophysics and Astronomy & Astrophysics. Professor Leo Pollak was appointed Director of the School and Head of the Geophysics Section in 1947. Prof Pollak’s history of strong support for the benefits of geophysical research had long been clear, in 1943 he had sent a memorandum to the Department of the Taoiseach, where he stressed the lack of training and research in geophysics, arguing that “to change this situation, not only unworthy of a cultivated and civilised nation but also injurious to its economic life, the establishment of a school for geophysics is proposed.” His vision was realised four years later with the founding of the School of Cosmic Physics and its Geophysics Section.
Hermann A. Brück First Head of Astronomy Section in the School of Cosmic Physics The School of Cosmic Physics is divided into broad sections of study, Astronomy & Astrophysics and Geophysics. In 1947, at the invitation of An Taoiseach Éamon de Valera, Prof Brück took charge as Head of the DIAS Astronomy section. After Dunsink Observatory was transferred to state ownership and attached to The Institute, Brück transformed it into a centre of modern observational technique, installing a large solar telescope and spectrograph as its principal instruments.
