Obituary


"It's tough to make predictions, especially about the future" - Yogi Berra

Stephan was first and foremost a loving husband to Madeleine for over 54 years, a wonderful father to Patrick and Christian, a warm grandfather to Lily, Ivy, and Otto and dependable friend to countless people.

After earning his medical degree in Germany and PhD from the University of Edinburgh, Professor Stephan Strobel became a pioneering immunologist at UCL and Great Ormond Street Hospital, whose groundbreaking research on oral tolerance to food antigens transformed our understanding of food allergies and autoimmune diseases. Professor Strobel has published 200 research papers that were cited over 8,800 times (and counting) and co-edited the Great Ormond Street Handbook on Paediatrics.

When he retired on health grounds 17 years ago, Stephan, together with his wife Madeleine, decided to devote their time to their shared passion of sailing on their Bowman 40; Easy Rider. In addition to sailing extensively throughout Europe (to stay close to medical care), Stephan and Madeleine co-edited two editions of the highly acclaimed Corsica and North Sardinia pilot book published by Imray in collaboration with the RCC Pilotage Foundation. Stephan and Madeleine also served for 4 years as Honorary Stewards of the RCC and their last dinner was just a short month before he passed away.

Stephan will be sorely missed but not forgotten.

Career


Stephan earned his medical degree (MD) in Germany at Universitätsklinikum Frankfurt and obtained a PhD from the University of Edinburgh.

Stephan became a distinguished professor at the University College London's Institute of Child Health and served as a clinician at Great Ormond Street Hospital for Children. He specialized in pediatric immunology and clinical immunology and became a prominent researcher in the field of immunology, particularly in oral tolerance and food allergies.

Research Focus and Contributions
Professor Strobel was a pioneer in the study of oral tolerance to food antigens, which became a major area of his research and in which he made significant contributions to understanding immunological mechanisms in food allergies and autoimmune diseases.
He published groundbreaking work on how exposure to mucosal antigens can lead to immunological tolerance and extensively studied mechanisms of allergic reactions and immunoregulation. His research has been highly influential.  Stephan published over 200 research papers throughout his career with his publications being cited over 8,800 times

Academic Achievements and Recognition
He was awarded honorary membership of the Royal College of Physicians (MRCP Hon), became a Fellow of the Royal College of Physicians (FRCP) and a Fellow of the Royal College of Paediatrics and Child Health (FRCPCH). Stephan also co-authored important position papers for the European Academy of Allergology and Clinical Immunology (EAACI)

Later Career
Later in his career, Stephan was appointed Emeritus Professor of Paediatrics and Clinical Immunology at the University of Plymouth and continued as Honorary Professor of Paediatrics and Clinical Immunology at University College London Institute of Child Health. More recently he co-edited the highly respected "Great Ormond Street Handbook of Paediatrics," which has been described as "the best paediatric book" by the British Medical Association

Throughout his career, Professor Strobel made significant contributions to the fields of pediatric and clinical immunology, particularly through his pioneering work on oral tolerance and food allergies. His research has helped shape our understanding of immunological mechanisms and has influenced treatment approaches for allergic and autoimmune diseases.

It is with great sadness that we learned of this amazing man’s passing . Over dinner today we were discussing brilliant doctors and of course Stephan was mentioned . When googling we were shocked to find he was no longer with us . Stephen looked after our son Simon for many years at GOSH after the amputation of his leg due to serious infection . He was a gifted and exceptional doctor who steered us through many storms with patience kindness and a witty sense of humour . He will be sorely missed by many families like ours who always need that “rock” in their life on whom they can depend to keep their loved ones safe . Our condolences to his family and colleagues . With love from the Pole family x

Dr Strobel looked after my very young son when we were referred down to GOSH from Liverpool in 1988. He had a complicated immunological problem and for me as a young mum, with another child left at home, I was very anxious. Dr Strobel was incredible, spending hours back and forth the ward. He was so kind and reassuring and thought it hysterical that I was sleeping just off the ward on a shelf in an old linen cupboards, with another mum sleeping opposite me. My son is now 40 years old , married with two small children and , most importantly, very healthy. I will never forget this doctor ❤️

Completely out of the blue, for some unknown reason whilst browsing on my computer I decided to Google Stephan to see what he was up to these days. I was very shocked and saddened to read that he has very recently passed away. I knew him when I worked for him for several years at the Institute of Child Health, most notably as the administrator for the MSc in Clinical Paediatrics.
My sincere condolences go to Madeleine and family.

I was very lucky indeed to have worked with and for such a delightful, kind, interesting and talented man.
We worked hard and we had a lot of fun in the Institute of Child Health Dean’s office.
Stephan’s twinkly sense of humour was a key part of that.
Stephan was a family man and I remember how emotional he became when telling me of a success in his family.
He was a special person and a role model for us all.

I knew Stephan for thirty years as a neighbour and friend. What I admired most about him was that everything flowed from his cheerful and solid core: his broad smile, his obvious love for Madeleine, his innate wisdom that made him the ‘grandfather of the gardens’, his curiosity about people, science, medicine, music, music technology- everything really. I was grateful to him for encouraging me in my medical career and always being interested in my family. I was in awe of the fortitude, courage and team work he and Madeleine showed with the ocean sailing trips in ‘Easy Rider’ and loved reading their blogs and their book. Most recently, it felt important to get Stephan’s blessing of a new relationship, such was my respect for his judgement. Of course, he gave it, and we have all enjoyed some happy dinners together in the last few years – and we look forward to more with Madeleine although we will keenly miss Stephan’s lovely presence.
Herr Dr Dr Professor Professor Strobel, we will never forget you.

It was with great sadness that I learned of Stephan's passing. I first met him when he arrived at the Institute of Child Health and Great Ormond Street Hospital whilst I was still a junior doctor. I remember him as being a kind and caring clinician. He was always interested in what his peers and juniors were doing and always supportive and encouraging. Stephan was an excellent teacher and his record in this sphere, including the GOSH Handbook, is an important part of his legacy alongside his considerable research achievements.
I am sorry that I will not be able to attend the memorial service but my thoughts and sympathies will be with Madeleine and the family.

I have very nice memories of Stephan from his time working in the Immunobiology Unit at the Institute of Child Health, which I joined in 1997. Our last contact was during Covid lockdown, when he emailed me to check how I was doing in those difficult times and he mentioned he was going to be editing the third edition of the GOSH Handbook of Paediatrics. I will not be able to attend the service but offer my condolences to Madeleine and the family. Stephan had a great smile and sense of humour and leaves a great legacy.

Als Lebenspartnerin und Ehefrau des mittleren der drei Strobelbrüder trauere ich nun um meinen Schwager Stephan. Er hat damals in 1997/98 die Therapie von Thomas überwacht, konnte ihm aber nicht helfen. Als mein späterer Freund und Lebenspartner in 2023 ebenfalls an Bauchspeicheldrüsenkrebs erkrankte, analysierte er für mich die Arztberichte. Dafür war ich ihm sehr dankbar.
Ich denke an Stephan als einen sehr kommunikativen Gesprächspartner, er war in allen Themen zuhause, Wir sprachen oft über den Sport, er übers Segeln, ich übers Segelfliegen. Seine humorvolle Art wird mir fehlen.
Ich wünsche Madeleine, Patrick und Christian mit Familie viel Kraft, das Geschehene zu verarbeiten und bin in Gedanken bei Euch. Alles Liebe

Dear Stephan, how I miss you. But reading all the comments and loving messages above, I realize how important you were not just to close friends but to the world in general. You saved lives, you worked tirelessly for others' benefit, and you also enjoyed your own life to the hilt, with the sly humour that others have appreciated. You moved through life with such grace and modesty that until I read some of your colleagues' comments, I didn't quite realise what a brilliant and influential physician and scientist you were.
With love always from a former Great Ormond Street baby (class of 1942) Ros

It was a real shock to hear of Stephan’s passing. He always seemed so alive, with a life full of experience but ready for new adventures. To us neighbours he was a considerate, sympathetic presence, which we shall much miss. Ein echt sanfter Mann.

Wonderful looking at the photos, such happy memories to treasure. Stephan was so kind, generous and a wonderful sense of humour, the twinkle in his eye with such a straight face when teasing- never to be forgotten xxx

We are so lucky to have counted Stephan and Madeleine as very dear friends and neighbours for almost thirty years. Stephan’s impish humour, his good sense and his wise advice enriched our lives. We and our children will not forget.

Stephan will always hold a very special place in my heart, he was such a unique person, who welcomed me into his professional arms at the Institute and was always there for me whenever I needed support professionally and at times with my personal life. He also made me work very hard and I loved every moment of our time working together! I have such fond memories of him, his kindness and his sense of humour, and how he sometimes struggled to understand my relaxed Mediterranean ways, we always had a good laugh.

I know how much he loved Madeleine and his sons, you must all be missing him so deeply.

. I will be raising a glass celebrating with you all the life of a very special man that I was blessed to have met.

I have had the great honour and joy of having Stephan as a cousin all my life, and have felt very close to him (and his beautiful Madla) particularly for the past 25 years.
Stephan was brilliant and wise but above all he was kind. I cannot count the amount of times he patiently and generously listened to me and
gave me wise medical advice about my kids when I was worried. One night, when I called him panicking when my 7 year old had swallowed a small metal duck, he just asked calmly ‘Is she breathing?’. Startled, I said yes, ‘Good’ he said, ‘then give her some porridge that will help it come out the other side’. To me, that was him, the person who always knew what to say, what to do, to steer any ship in stormy waters.
Another thing about Stephan that stays with me is his marvellous sense of humor and hisbcuriosity to learn and explore new things. We spent a marvellous Christmas day this past December. He made time to chat to each person that was there. He tried out my sons new earphones and was happily lost in the music and doing a little dance and tapping his foot as he listened to jazz and rap. My family all adore him and are enormously saddened by this tremendous loss. We will keep his wise words, his intense curiosity and his lovely open smile in our hearts forever. We accompany his brother, his beloved Madla, Patrick, Christian, Sydney, Alex and the grandkids in mourning this sad loss and celebrating his life. We keep him with us and are grateful for the marvellous memories. Thank you, Stephan. Our world is so much lesser without you here.

I write on behalf of the executive team at GOSH to offer our sincere condolences following Stephan's death.

I had the honour and the pleasure of being one of Stephan's MSc Clinical Paediatrics students back in the early 2000s. He was simply phenomenal. Those of us who were his students remember him with such admiration and fondness. It is no exaggeration to say that he was instrumental in the careers of so many of us. We were often early career paediatric registrars who desperately wanted to advanced our knowledge. So many of us then went on to do PhDs and became specialists in our fields , influenced by how Stephan shared his love of paediatrics and his wisdom of life. He was always such a gentleman and showed us how to maintain our professionalism in all that we did in service of the care of children and young people. I have thought of Stephan many times over the years in gratitude and personal reflection on his impact.

With sincere sympathy

- - und plötzlich bleiben nur die Erinnerungen: an Stephans Ernsthaftigkeit und weiten Horizont, an seinen Humor, sein junges Lächeln. Bei hohen Geburtstagen – in der Gare de Lyon, auf der Spree, in Sils Maria ... in den windigen Klippen von Newton Ferrers und schwindlig unter den süddeutschen Barockkuppeln ... Ein bloss sehr kleiner Trost, doch wenigstens ein Trost.

I’ve waited to write this, principally because I find it difficult to accept the finality of Stephan’s passing. He was clearly a great man, his work, pioneering and significant, but he was above all else, a thoroughly decent human being. He lacked any kind of hubris and had an unconditional interest in other people.

The last time Faith and I saw Stephan was at Café Oto, where we’d gone with Madeleine to see Park Jia. Thinking about it reminds us of his tremendous curiosity, his thoughtful reflections and his natural way with people, how he struck up an easy conversation with a young guy who’d come to performance alone. And also, his wry smile, which was usually accompanied by a slightly mischievous twinkle in his eye.

It has been an absolute pleasure to know him; a bright man who didn’t feel he needed to dominate a room, a calm presence and a fundamentally generous soul.

Als Ältester von uns drei Brüdern bin ich als einziger noch am Leben und trauere um meinen " kleinen" (in jeder Hinsicht
" größeren ") Bruder. Ich habe ihn an allen wichtigen Orten seines Lebens begleitet: Vom " Fischerhof " in Uelzen, über Büdingen,Gin- Gins, Frankfurt , Edinburgh,London,
Newton Ferrers, zurück nach Hampstead.Zuletzt haben wir uns wenige Wochen vor seiner Operation in Hamburg gesehen bei einem Konzert und einem Abendessen mit der ganzen Hamburger Familie.
Seine lebensbestimmende Eigenschaft war seine rundum positive und beruhigende Ausstrahlung - sein
" positive thinking ".
Für mich und meine Familie war er stets der ärztliche Ratgeber in allen nur denkbaren Situationen. Bis heute bin ich ihm dankbar für seinen Rettungseinsatz, mit dem er mich aus Italien ausfliegen ließ.
Seine positive Einstellung ließ ihn auch hoffen, daß seine geplante Operation trotz aller Risiken zu einer Verbesserung seines Zustandes führen würde. Leider trog ihn diese Hoffnung.
Ich trauere mit meiner Familie zutiefst um meinen lieben Bruder,unseren Schwager, Onkel und Großonkel. Unsere Gedanken sind bei dir, liebe Madeleine und euch, Patrick und Christian und euren Familien.

When I remember Stephan what comes to mind is that he was such a warm and welcoming uncle, with a witty sense of humor, funny dancing steps and an intelligent point of view when in need of an answer or opinion. Stephan along with Madeleine invited me along on a sail vacation to Greece, which I so fondly remember. I also recall the visit to Newton Ferrers, the New Years in La Trappistine, the many pool side family gatherings in Gingins, the visits to Gainborugh Garders. Each and every time Stephan was a reassuring man to me. These last years we had not seen much of each other, but time has not dilapidated in any way all these memories which are solidly kept in my heart. Stephan, I hope you are sailing wonderful waves. My thought to Madeleine, Patrick and Christian.

A tribute in song to Stephan and Madeleine
Listen on you tube it is beautiful
We send it with our love, thoughts and prayers

The Voyage
by Christy Moore (Lyrics)

I am a sailor, you're my first mate,
We signed on together, we coupled our fate,
Hauled up our anchor, determined not to fail,
For the hearts treasure, together we set sail.

With no maps to guide us we steered our own course,
Rode out the storms when the winds were gale force,
Sat out the doldrums in patience and hope,
Working together we learned how to cope.

Life is an ocean and love is a boat,
In troubled water that keeps us afloat,
When we started the voyage, there was just me and you-
Now gathered around us, we have our own crew.

Together we're in this relationship,
We built it with care to last the whole trip,
Our true destination's not marked on any charts;
We're navigating to the shores of the heart.

Life is an ocean and love is a boat,
In troubled water that keeps us afloat,
When we started the voyage, there was just me and you-
Now gathered around us, we have our own crew.

Life is an ocean and love is a boat,
In troubled water that keeps us afloat,
When we started the voyage, there was just me and you-
Now gathered around us, we have our own crew.

Nous avons tant partagé: des paysages, des vagues (pas trop grandes pour Suzanne et pour moi), des repas, Jim Rummy, des conversations, la famille, le monde.
Stephan et son sourire.
Ses arguments toujours solides et réfléchis.
Sa présence rassurante pour aller de l'avant.
Maintenant son absence.
Rendez-vous là-haut.

In becoming an adult and a pediatrician, I have been greatly inspired by Stephan!
Working and living with him (and Madeleine!) for four months back in 1995 has given me a good mindset.
Seeing him as an excellent doctor, teacher and researcher, a wonderful husband, father, uncle and friend- kind, creative, ambitious, determined, hard working, sometimes stubborn, a cat lover- has widened my perspective on myself and life.
Full of loving memories, your nice Nane

Stephan was an amazing and gifted clinician and researcher who sparked my interest in research when I started studying for my MSc in Clinical Paediatrics in 1998 at University College London Great Ormond Street Institute of Child Health (a course which he led for many years). He sparked off a research career for me and like him, I became a professor at University College London, following in his footsteps. We had fun together over many years, especially editing three editions of "Great Ormond Street Handbook of Paediatrics" - the latest of which is already being printed but unfortunately, he will miss the launch. Our thoughts are with Madeleine and her family at this difficult time. He will be sorely missed. May his dear soul rest in peace, Stephen Marks

Oh gosh Madeleine, such a shock to hear this news. I loved Stephan's lovely dry sense of humour, his precision and his smile. You were the perfect couple, made for each other actually. I visualise you as newly weds buying pottery in the markets of London and Edinburgh building your amazing collection and of course onboard Easy Rider. Condolences from all of us at Carswell, our thoughts are with you.

We will deeply miss your warmth, wit, brilliance and kindness.
It was only a few weeks ago that we were all exchanging stories and adventures over cheese and wine in Edinburgh, where we met over forty years ago.
Decades of walks, exhibitions, films (you introduced me to the work of John Cassavetes and many others) dinners together and long rewarding conversations.
Many years ago in a remote part of Turkey your quick thinking saved us all.
Heart warming intelligence, affection and imagination. From Lola to Felix.
With deepest sorrow and celebration of your beautiful life.
