Birth of Physicist Daniel Joseph Bradley

Daniel Joseph Bradley, physicist and Emeritus Professor of Optical Electronics at Trinity College, Dublin, is born on January 18, 1928 in Derry, County Londonderry, Northern Ireland.

Bradley is one of four surviving children of John and Margaret Bradley, Lecky Road, Derry. He leaves school to work as a telegraph boy but returns to education at St. Columb’s College. Following training as a teacher at St. Mary’s Training College, Belfast, he qualifies in 1947. While teaching in a primary school in Derry he studies for a degree in mathematics as an external student of the University of London, and is awarded a degree in 1953.

Moving to London where he teaches mathematics in a grammar school, Bradley decides to register for an evening course at Birkbeck College. His first choice is mathematics but as he already has a degree in the subject the admissions staff suggests that he study physics. In 1957, after four years of part-time study, he is awarded a Bachelor of Science degree in physics by Birkbeck, achieving the highest marks in his final exams in the University of London overall. He next joins Royal Holloway College as an assistant lecturer and simultaneously enrolls as a PhD student, working on Fabry–Pérot interferometer etalon-based high-resolution spectroscopy supervised by Samuel Tolansky. He receives a PhD in 1961.

Bradley is a pioneer of laser physics, and his work on the development of ultra-fast pulsed lasers adds a new and vitally important element to the capabilities of this new type of light source. In particular, working on dye lasers, he produces pulses of light as short as one picosecond (one picosecond is to a second as a second is to 31,800 years). His work paves the way for the completely new field of non-linear optical interactions. In addition, he inspires a new generation of laser scientists in Ireland and the UK, many of whom are international leaders in their fields.

Appointed to a lectureship in the physics department at Imperial College London, Bradley sets up a research programme in UV solar spectroscopy using rocket technology to reach high altitudes.

In 1963 Bradley begins work in laser physics but returns to Royal Holloway College as a reader one year later. In 1966 he is appointed professor and head of department at Queen’s University, Belfast. There he quickly establishes a space research group of international standing to do high-resolution solar spectroscopy. He attracts significant funding from a variety of agencies, allowing him to build his department into one of the world’s leading laser research centres, involving a total of 65 scientists. However, he leaves Belfast because of fears for his family’s safety as political violence escalates in the early 1970s amidst The Troubles.

Bradley returns to Imperial College London in 1973 to a chair in laser physics and heads a group in optical physics, laser physics and space optics. He is head of the Physics department from 1976 to 1980 but is frustrated by cutbacks and a rule governing the ratio of senior to junior positions, one consequence of which is that he is unable to maintain a long-established chair in optical design. He is also critical of the college administration’s handling of some departmental grant applications. He resigns in 1980 and moves to Dublin.

Among Bradley’s many lasting contributions to laser research in the UK is the setting up of one of the world’s leading research facilities for laser research, the Central Laser Facility at the Rutherford Appleton Laboratory (RAL).

Arriving at Trinity College, Dublin, Bradley decides the time is ripe to move on from laser research and development into laser applications. In 1982, with Dr. John Kelly, a chemist, and Dr. David McConnell, a geneticist, he forms a team which wins funding for a project using laser techniques to explore the structure of organic molecules like DNA and proteins. Unfortunately, however, his work at Trinity is cut short by ill health and he retires in 1984. His research on semiconductor lasers is carried on and this work on developing widely tuneable lasers for optical communications systems continues.

A member of the Royal Irish Academy, Bradley is Fellow Emeritus of Trinity College Dublin, and holds fellowships of the Royal Society, The Optical Society of America and Institute of Physics. Through time the ravages of his illness restricts his travelling and eventually he is cared for in a residential home in Dublin, where he passes away on February 7, 2010.

Magee College Opens in Derry, County Londonderry

magee-college-1870Magee College opens on October 10, 1865 as a Presbyterian Christian arts and theological college in Derry, County Londonderry, Northern Ireland. Since 1953, it has had no religious affiliation and provides a broad range of undergraduate and postgraduate academic degree programmes in disciplines ranging from business, law, social work, creative arts & technologies, cinematic arts, design, computer science and computer games to psychology and nursing.

The Magee Campus gains its name from Martha Magee, the widow of a Presbyterian minister, who, in 1845, bequeathed £20,000 to the Presbyterian Church in Ireland to found a college for theology and the arts. It opens in 1865 primarily as a theological college, but accepts students from all denominations to study a variety of subjects. It is a college of the Royal University of Ireland from 1880 and later becomes associated with Trinity College, Dublin when the Royal University is dissolved in 1909 and replaced by the National University of Ireland.

During World War II, the college is taken over by the Admiralty for Royal NavyRoyal Navy operational use, becoming with Ebrington Barracks (HMS Ferret), a major facility in the Battle of the Atlantic. A 2013 BBC report describes a secret major control bunker, later buried beneath the lawns of the college. From 1941 this bunker, part of Base One Europe, together with similar bunkers in Derby House, Liverpool and Whitehall is used to control one million Allied personnel and fight the Nazi U-boat threat.

In 1953, Magee Theological College separates from the remainder of the college, eventually moving to Belfast in a 1978 merger that forms Union Theological College. Also in 1953, Magee College breaks its ties with Dublin and becomes Magee University College. It is hoped by groups led by the University for Derry Committee that this university college would become Northern Ireland’s second university after Queen’s University Belfast. However, in the 1960s, following the recommendations in The Lockwood Report by Sir John Lockwood, Master of Birkbeck College, London and former Vice-Chancellor of the University of London, the Parliament of Northern Ireland makes a controversial decision to pass it over in favour of a new university in Coleraine. Instead it is incorporated into the two-campus New University of Ulster in 1969. The next fourteen years see the college halve in size, while development focuses on the main Coleraine campus.

In 1984, the New University merges with the Ulster Polytechnic, and Magee becomes the early focus of development of a new four-campus university, the University of Ulster. Student and faculty numbers recover and grow rapidly over the next ten to fifteen years, accompanied by numerous construction projects. Magee grows from just 273 students in 1984 to over 4,000 undergraduates in 2012. In 2012, the University continues to lobby the Northern Ireland Executive for an additional 1,000 full-time undergraduate places, leading to 6,000 students at Magee in 2017.

On September 14, 2013 Magee hosts, for the first time on the island of Ireland, the 23rd International Loebner Prize Contest in Artificial Intelligence based on the Turing test proposed by the renowned British computer scientist Alan Turing in 1950. Turing also works on cracking the Enigma machine code at Bletchley Park which is instrumental in the Battle of the Atlantic.

In October 2014 the University of Ulster is rebranded as Ulster University.
