Dr. Rex Dark

I have only just learned (19th January 2023) with very great sadness of the death of my friend Dr. Rex Dark. May he rest in peace and rise in glory. Sincere condolences to his brother Michael and his family.
Rex Dark was a Christian gentleman, one of the most brilliant mathematicians ever to work in Ireland, and loved and respected by his many students in Galway. He was generous to an unbelievable degree and exceedingly helpful to me mathematically since I first met him many years ago. Yet he was incredibly modest about his achievements and wore his learning very lightly.
Farewell dear Rex until we meet again in Heaven.

Condolences to the family of the late Rex Dark, great lecturer and colleague. May he rest in peace.

I am saddened to learn of Rex's death. He was a much valued colleague and friend. A world - class mathematician, Rex had also an extraordinary range of interests and abilities. He was a wonderful asset to the mathematics department, to the College and to the community at large. Personally he was courteous and had a quiet sense of humour which I recall as always pleasant and timely. I offer my sincere condolences to Rex's brother Michael and his extended family, and also to the many who became his good friends. May he rest in peace.

I was very saddened to hear of Rex’s passing. He was a great lecturer and, in spite of his modesty, an inspiring figure. I enjoyed chatting to him on the Connemara mountains and at Groups in Galway conferences. My sympathies to his friends and family, especially his brother Michael.

Sincere condolences to Michael, family and friends. Rex is well remembered by former members of UCG Mountaineering Club and Galway Mountain Rescue Team.

Sad news that Rex has died, saw him in Galway only recently. Condolences to his family.

Rex was a great colleague. His humility, quiet humour, kindness and erudition will be missed.

I was enthralled by the depth of Dr. Dark's mathematical knowledge and his boundless ability to put it across during my time 73-77 in UCG. In later years we met at a railway station, exchanged numbers and planned to meet.....alas...made a profound and lasting impact.

Sympathies to Michael and extended family on the passing of Rex. May he Rest in Peace. .

I was saddened to learn of Rex's death. A fine colleague, of innate courtesy and with a wry sense of humour, he will be remembered with fondness by all who came to know him during his years in Galway.

A great educator during my time in UCG in the late 70's. He made it easy to understand the subject with his patience and dedication to all his students. A ''Gentleman and a Scholar''. May he RIP.

Sincere condolences to Rex’s family and colleagues on his sad and sudden passing. I have very fond memories of Rex during my time at UCG in the 80’s. I particularly remember his sense of humour, his impeccable dress sense and his folding bicycle! Needless to say, his advanced algebra lectures were most enjoyable too. May he rest in peace.

With deepest sympathy to Michael and the extended family at this sad time. I am very sorry to learn of Rex’s death. He was the quintessential gentleman, always courteous and impeccably dressed. His boundless energy during lectures and perpetual good humour are among my abiding memories of my years in UCG. May Rex rest in peace

I knew Rex through many years of IMS and DIAS meetings. He was a loyal supporter of the Irish Mathematical Society and a dedicated committee member, always willing to help out. As mentioned many times before, his affable, genial manner and his humility made him beloved by everyone. May he rest in eternal peace. He will be greatly missed in the world of mathematics in Ireland and abroad.

Sorry to see that Rex Dark has died. He lectured me in 2002 and was a great guy, really encouraging and kind. Very dapper and well turned out for 9am class!
May he rest in peace.

RIP Rex and my condolences to his brother and family. A class gentleman and scholar. Perhaps,
our loss, he was not President of UCG.

Deepest sympathy to Michael and family on Rex's sudden death.
A fine man and a life well-lived, gone now to his eternal reward.
May his gentle soul rest in peace.

Sincere sympathy to Rex's family and friends on his passing. May he rest in peace.

Condolences to Rex's family, we met Rex through hill-walking and he was a familiar figure flying past our house on the bike on his way to and from work. May he rest in peace.

My sincerest sympathy to Rex's family on the death of Rex.

May his gentle soul rest in peace.

Sincere sympathy to Michael and the Dark family on the untimely death of Rex a real gentleman.

Sad news that Rex has died, a fantastic lecturer, great communication skills and really made Maths sing. He could see things in a way that others could not and was a decent man who helped both the very able and less able students.
Ar dheis Dé agus Mhuire go raibh a anam uilig.

My deepest condolences to Rex's family and friends on their sudden and sad loss. He was held in the highest esteem by all his colleagues in the Department of Mathematics, and indeed throughout the College. I have vivid memories of his first lecture to the 1st year class in October 1973. He was very helpful to junior colleagues and very generous with his time. Sad to think such a brilliant mathematical mind has ceased. Ave atque vale.

Where to start with Rex, an extraordinary person, and a sometime chorister many years ago. His contribution to church and community extended beyond city and county and travelled with him wherever he was, Galway, France and latterly Mayo. Sincere condolences to his family of whom he spoke so warmly.

Very sad news, condolences to Rex's family and friends. Rex was a kind and helpful colleague when I first arrived to work at NUIG in the nineties. I remember, even in my first year in Galway, being invited to a get together at his house in Moycullen. Even after his retirement, he came regularly to maths seminars in Aras De Brun. Thinking of this, and the many times I saw him cycling in to the University from Moycullen on his bike - I think the phrase "mens sana in corpore sano" is very apt. May he rest in peace.

So sorry to hear of Rex's death. I (Michael) had offices in the same building: the one & only Áras de Brún. Always lovely to meet Rex. A scholar & a gentleman; mathematician, Francophile & more besides. Only heard good things about his lectures to generations of Maths students in UCG/NUIG. May be rest in peace. Michael and Máire O'Connell, Galway

Sincere condolences to Rex's family and friends. His efforts and his insights, as well as his kindness, had a big influence on several generations of maths students in Galway, including me back in the 1990s. I had the good fortune to know him subsequently as a colleague. He was loved and appreciated by all who encountered him, and he is remembered with affection and gratitude.

Dr Dark was my project supervisor during my final year. He was always courteous and encouraging. He had a quirky sense of fun and humour. I was proud and lucky to be his student. A gentleman, may he rest in peace.

Deepest condolences to Rex’s family on his death . May his good soul rest in peace…. A scholar and a gentleman .

We are very sad to learn of the loss of our colleague and friend Rex Dark.
We last met him in June this year in Ischia (Naples, Italy) during the Ischia Group Theory Conference, he gave a wonderful talk, clear and pleasant as always.
Our deepest condolences to the family!

My sincere sympathy to the Dark family as they mourn the loss of Dr Rex Dark… I remember him so well as an amazing teacher when I was in UCG!!(1975)! He had such a clear and distinct voice … rest in peace .

Sincere condolences to Rex's brother on his recent passing. A character here in Moycullen and is sadly missed. RIP Rex.

Condolences to the family on your loss. Always a great Maths lecture to attend.
May Rex rest in peace

A great educator and personality during my undergraduate days in UCG. May he rest in peace.

May you rest in peace DR Dark Yours was the only name I really remembered from all my lecturer’s,a brilliant maths lecturer,so understanding and always willing to give extra time .Sincere condolences to his brother and extended family.

Shocked to read that Rex has died. Condolences to his family, friends and former colleagues in the Maths Dept, I met him on campus just a few weeks ago. I knew him from when I worked in the Botany Dept in the same building and he was an engaging and popular lecturer with first-year students in particular as he eased their transition to third-level studies. Friendly and at ease with everyone - from the Mountaineering Club, Meitheal an Rothar (his was the first folding bike I ever saw) and St Nick’s Choir - he was a complete gentleman.

We were shocked and saddened to hear of Rex’s passing. He was a great friend of ours and a wonderful colleague of Arny’s. For 23 years, we were privileged to work, eat, travel, converse, and laugh with Rex. During the pandemic, Arny spoke with Rex on the phone every week or two, always on Monday at 3:00pm Westport time. We will miss his quiet humor, cheerful demeanor, and brilliant mind. Our condolences to his brother and family, who brought him great joy.

I was an Engineering student in UCG in the early 1990’s and took Dr Dark’s maths class in 1st and 2nd year. In first year I thought he was teaching the “easy” part of the maths course. It was only in 2nd year when he taught a different part of the course that I realised he was just a brilliant lecturer who made it easy to understand the subject. He was so enthusiastic in class, always a joy to listen to him. At this stage I have forgotten a lot about my time in UCG but I haven’t forgotten him. Rest in peace Dr Rex. Condolences to his family.

So sorry to learn that Rex has died. In NUIG he was respected as a true gentleman, knowledgeable, kind, courteous and considerate. Always clean-cut and impeccably attired, he rode daily on his bicycle twixt Moycullen and University in fair weather or foul – his great yellow rain-cape in the distance signalling his approach. Sincere sympathy to his brother Michael and extended family. May he rest in peace.

Sincere Sympathy to family and friends . Thank you Sir for making maths so easy to understand. May you rest in peace .

So sorry to read of his passing
He was an excellent lecturer to us in 70's and very kind man.
God rest him now, and grant him the reward for a life well lived.

My sympathies to his brother and family. As many others have said, Rex was a true gentleman. He was also a pleasure to work with.

So sorry to hear that Rex has died. Condolences to his brother and family. I met him only 6 weeks ago in Westport while out walking and he appeared hale and hearty. We worked closely together in St. Nicholas Collegiate Church in Galway where he was Treasurer for 6 years and I was Secretary of the Select Vestry. He was meticulous in everything that he did, always good humoured and more than willing to go the extra mile to make sure all was correct He also sang with the choir and was a member of the Lamplighters - a drama group with links to the parish. When he moved to Westport the familiar figure of him cycling his bike into the University in his yellow raincoat was missed by many in Moycullen. Rest in peace dear Rex.

So sorry to hear this sad news. A thoroughly engaging lecturer and a gentleman.

Sincere sympathy to Michael and extended family on the death of Rex.
He was a conscientious, very kind academic and thorough gentleman.
Suaimhneas ar a anam uasal.

What a clever man he was. Rex made mathematics look so easy. Who could forget his multiplication of massive matrices and the resulting simultaneous equations in the freezing cold H Block prefabs. RIP Dr Dark and thank you.

I offer my condolence to Michael and the extended family on the passing of Dr. Rex. I remember his calming presence as an invigilator in the Aula. May his gentle soul Rest In Peace.
