Dunsink Observatory was founded in 1785 following a bequest from the Provost of Trinity College Dublin, Francis Andrews. Provost Andrews bequeathed £3,000 to establish a Professorship of Astronomy and to build an astronomical observatory. From 1792 until 1921, the Andrews Professor was the Royal Astronomer of Ireland, a title that was established by Letters Patent of King George III. According to the Statutes of the College, the Andrews Professor was required to “make regular observations of the heavenly bodies, and of the sun, moon and planets”. The holder of the Andrews Professorship was Director of Dunsink Observatory and lived and worked in Observatory House from 1785 until 1992.

Probably the most recognised scientist to hold the position was Sir William Rowan Hamilton who was appointed at the age of 21. His appointment was not without controversy as Hamilton paid little attention to his official “observational” duties, instead focussing on his research on more theoretical problems in physics, such as conical refraction, quaternions and mechanics.
Sir William Rowan Hamilton was Director of Dunsink Observatory and invented quaternions while walking along the banks of the Royal Canal.
The Andrews Professorship and Dunsink Observatory were abandoned by Trinity in 1921, but the Observatory was taken over by the Dublin Institute for Advanced Studies in 1947. The Royal Astronomer title lapsed in 1966 when TCD adopted new statutes.
The Andrews Chair was re-established as an honorary chair associated with Dunsink in 1984. An excellent description of the history of the Andrews Professorship and Dunsink Observatory by Prof. P. A. Wayman can be found in The Irish Astronomical Journal.
