Seán (John) Sheridan

I was very shocked and saddened to hear of Sean's sudden passing. I count myself very fortunate to have gotten to know Sean during my time in UCD Engineering and will be forever grateful for his advice, encouragement, humour, friendship, and the great generosity with which he shared his time throughout all classes and projects, great or small. My deepest condolences to all of Sean's family.

Sincere Condolences to Jutta, Daniel and Sheridan family on the untimely demise of Sean. I will never forget the warmth and affection that he showed all these years. He will be deeply missed. May his soul rest in peace.

My very deepest sympathies to Jutta, son and all of Sean’s family. I was very saddened to hear of Sean’s sudden passing. Sean was a true friend and colleague with a brilliant mind and unstinting good humour. His office was always open and he never wavered from an opportunity to discuss technical or philosophical issues on research and College topics of mutual interest. I will miss him greatly as one of the most authentic gentlemen within UCD Engineering. A tragic loss; rest in peace Sean.

On behalf of UCD Students’ Union, I would like to express my sincere condolences to the family and loved ones of Professor Sheridan. John was filled with light and cared deeply about the students of UCD. May he rest in peace.

John always reminds me of all the virtues of his generation, gentleness, decency, generosity, and most importantly, passion for life and research. He never hesitated to give guidance and support to those in need, and encouraged people with the utmost enthusiasm and kindness.
May he rest in peace.

So sad and shocked to hear of Sean's untimely death. We met him through our son when he was in UCD. Sean was such an inspiration for his students and kept up the contact long after graduation and into the workplace. Sincere condolences to his wife and son and all his loved ones on their great loss. May Sean rest in heavenly peace.

I was deeply saddened to learn of Seán’s untimely death. As well as being a very good friend and an outstanding researcher and teacher, Seán was a warm, witty and generous colleague whose infectious good humour and kindness lifted the spirits of everyone who came into contact with him. He was, in every sense of the word, a true gentleman. UCD will not be the same without him. My sincere condolences to his family. Ar dheis Dé go raibh a anam.

My sincere condolences to Jutta and Daniel and all the Sheridan family on the loss of your beloved Seán. He was a great colleague with a wonderful sense of humour. Also, Seán was a great teacher of students at all levels, and a leader in the academic arena. I will miss him, particularly in the mornings over coffee in the Engineering Common Room, where the “craic was mighty”. May he Rest in Peace.

Sincere sympathy to Máire and all the Sheridan family at this very sad time. May Seán's gentle soul rest in peace.

Deepest sympathy to Maire and extended Sheridan family on the sudden death of Sean. May he rest in peace

John was a gent, one of the good guys. His laugh would boom down the hall in the engineering building in UCD. You'd smile every time you'd see him. Sincere condolences to the Sheridan family. RIP.

Sincere sympathies to all the Sheridan family.
I was one of his undergrad students back in 2008/2009, “Photonics”! I admit, I never understood the lectures but I loved attending them because of him! He was always making little funny comments and jokes and I would take notes of them for later when I study for the exam to cheer me up!
The day before the final exam, he gave me a little piece of advice: “don’t marry anyone from academia. They’re too broke! He’ll just take you to the next paid conference for the honeymoon! That’s why I took my wife to Australia for our honeymoon!” And that’s the last thing I remember of him. ❤️
He was an amazing man. He will be truly missed. May he rest in peace.

Deepest sympathy to the Sheridan family & extended families on the sad & sudden passing of Sean. R.I.P.

My sincere sympathy to the Sheridan family on your sudden and sad loss. Sean was a classmate in St Patricks and St Gerald's as well as a neighbour in Saleen. We attended each others birthday parties and my late Mam, Marie gave Sean a lift to school every morning. Thoughts and prayers are with you all at this sad time. RIP Sean.

I will miss Seán so much. His "good morning chief", "take good care of yourself man" and his funny stories would always make my day brighter. Seán was one of the most beautiful persons I have met. He could 'read' me from a mile away and he would always ask me whether there was something he could do to help me out.
Sincere condolences to the Sheridan family.

We wish to express our deep sympathies to Lily & family, & Jutta & Daniel on the sudden & untimely death of Sean, you are in our thoughts and prayers at this sad time, May Sean Rest in Peace.

Sincere sympathy to Lily and Family on the sad passing of Sean, may he rest in peace.

Seán was the best colleague you could ask for. A highly accomplished researcher and educator, but at the heart of it all was a fantastic person. He always wanted the best for his students and colleagues and was incredibly supportive towards them. I always enjoyed meeting him on the corridor on his way to make one of his many cups of tea. “Chief”, “Another day another dollar”, “No rest for the wicked” were his more common phrases, as well as bemoaning Mayo’s latest failure to beat the Dubs. The UCD Engineering staff common room will be an emptier place without him. Gone but never forgotten.
May he rest in peace.
Deepest sympathies to Jutta, Daniel, Lily, Maire, Louise, Tom, Michael and the entire Sheridan family.

To Jutta, Danny and the extended family - my thoughts are with you during this very sad time. I only met Sean recently but from the few meetings we had and from Jutta's stories, it was obvious what a special man he was and how much he will be missed by everyone. I would have loved to get to know him better.

Jutta and Daniel and the Sheridan family, my deepest sympathy to you at this sad time. Séan will be deeply missed at UCD and around the Engineering building. I will remember him for his warmth, his kindness and his care for his students and how he always found a way to bring his family into a conversation with pride and affection. RIP Séan.

My heartfelt condolences to Jutta, Daniel, and all of the Sheridan family.

Dear Lily and all the Sheridan extended family my sincere sympathy to you all on the loss of Sean.May Sean now rest in eternal peace.

Deepest sympathies to the Sheridan Family on Seán's untimely passing. He had a deep commitment to his students and was always a great advocate for them. He will be missed. May he rest in peace.

To Sean's family: so sorry for your loss. He was a magnificent person - sharp, warm, down to earth, funny, and above all caring. I'm sure he's up there somewhere shining his lasers down on us all.

Jutta and Daniel, my deepest sympathy to you and your extended family at this very sad time. Seán was a wonderful colleague and always generous with his time, advice, and a kind word or a joke. He was thoughtful and considerate of all, and I will remember him with great respect and affection.

RIP Seán

I am deeply shocked and saddened to hear of John's untimely demise. In his passing away, the optics community lost an outstanding scholar and a passionate teacher, The void left by his passing away will be felt by his colleagues, friends, admirers, and students for a long time to come. I had the privilege to have known him for many years and interact with him in person and through correspondence. He was always ready to help and share his knowledge freely. John had a great sense of humor and his laughter was infectious. His conversations with me revealed that he was very much interested in Indian history. I will deeply miss you, John.
My deepest condolences to the bereaved family. May he rest in peace!

My deepest sympathies to all of Sean's family and friends on his sudden passing.

I bumped into Sean (or JTS as he signed off with on email) regularly in the staff room in the Engineering building. He was such a gentleman; always with a smile on his face and up for a chat and a joke (and always managed to get Mayo into the conversation!). He will be missed.

May he rest in peace.

Sean was a caring human being, and good friend, and a leader. I am grateful for his friendship. Heartfelt condolences to Jutta and Danny and the entire family.

My deepest condolences to Jutta and Daniel and all of Seán's family.

Our deepest sympathy to Jutta, Daniel, Lily, Michael, Maura, Louise,Tom, and all Seans extended Family and friends. Thinking of you all at this difficult time. May he rest in peace.

Jutta and Daniel,

My deepest sympathies to you both on Seán’s passing. He was such an important mentor and friend to me. He said yes with a hearty laugh to a crazy idea when many others were saying no. That led to the development of a technology that has made a real change in an industry far apart from his own.

His generosity, kindness, wit, intelligence, loyalty and deep love and respect for his family, and especially both of you, will persist in the hearts and minds of all his colleagues and friends. I am blessed to have known him and have benefitted from his friendship and mentorship.

You are in my thoughts and prayers at this difficult time. He truly was an amazing human.

RIP Seán

Deepest sympathies to Jutta, Michael and all of Sean's Family and extended Family at this time.

He will be missed by everyone who had the honour of knowing him. Rest in peace Sean.

Deepest sympathies to the Sheridan family. Remembering Sean fondly, always such a kind and bright presence in UCD Engineering.

We worked together only once, but I will remember him forever. My sincere condolences to all those who knew and loved Sean. May Sean rest in Peace.

Sincere sympathies to Jutta, Daniel & family, on Sean's sudden passing.

Even though I only knew him a couple of months, as a new staff member of the Engineering & Architecture College staff, he was always there for me while his humour & straight talking was unique and reassuring.
