His post graduate training was undertaken in Birmingham in general practice initially and subsequently in Ophthalmology. He was appointed to the Mater Hospital and Richmond Hospitals Dublin in 1975. His energy was boundless and his enthusiasm was infectious. He had great interest in-patient care and was readily available to colleagues and trainees in particular, who he enjoyed teaching and mentoring. Peter took a keen interest in their examinations and surgical training, developed many research projects and encouraged the trainees to present at national and international meetings. It is fitting that he was appointed as Professor of Ophthalmology to University College Dublin and the Mater Hospital Dublin in 1982. He developed the Mater Eye department with a number of Consultant appointments each with a sub-specialty interest, forging strong links with Temple Street and the Beaumont Hospitals. Peter co-authored of *Neuro-ophthalmology* which was published in 1998. He established the first EBO diploma examination in Milan in 1995 to enable recognition of European training as he strongly supported the European Board of Ophthalmology and the harmonisation of training in Europe.

He was a co-founder of the British Isles Neuro-ophthalmology (BINOC) club with Bruce Noble in1984. All attendees were required to present a paper. Peter organised the third meeting in Ireland which was the first of several meetings held in this country. Peter was always at the centre of the discussions and is remembered for his gentle wit and great scholarship. BINOC meets annually and is attended by distinguished neuro-ophthalmologists from the US and Europe and has brought great fellowship and support to all attendees. Peter was President of the Irish College of Ophthalmology in 1993-95. He was a champion golfer and a member of Dun Laoghaire golf club all his life and he enjoyed sailing.
