OBITUARIES

Dr. Costa served as a professor at FOUSP for 36 years. A devoted mentor to both undergraduate and postgraduate students, he inspired generations of colleagues with his passion for teaching and unwavering commitment to the field of Oral Radiology, shaping the careers of many. In his own words, “the greatest teachers are, in essence, simple and generous people”. This feeling was reflected in every aspect of his work. Over the course of his distinguished career, Dr. Costa received numerous awards and recognitions, a testament to his lifelong dedication and impactful contributions to Oral Radiology, bearing the fruits of a life devoted to the field.

He was the director of LAPI – Laboratory for Image Analysis and Processing at FOUSP – which houses an extensive collection of 2D and 3D imaging data. He also led the research group on Image Processing and Analysis in Dentistry, certified by the Brazilian National Council for Scientific and Technological Development (CNPq). More recently, he served as the faculty advisor for FOUSP’s Interdisciplinary Digital Dentistry League (LIOD).

Dr. Costa shared his experience internationally, serving as a visiting professor at institutions including Texas A&M University Health Science Center – Baylor College of Dentistry (Dallas, 1997) and the University of California – School of Dentistry (Los Angeles, 2005). In 2013, he visited several Japanese universities (Hiroshima, Osaka, Showa) to foster academic collaborations. In 2015, he was invited as a guest researcher at Aarhus University (Denmark), later coordinating FOUSP’s international cooperation project with the same institution.

In 2020, Dr. Costa became the head of FOUSP’s postgraduate program in Oral Diagnosis, Oral Radiology, and Imaging, a position he held until April 2024. He then continued to serve as a vice-coordinator until his final days.

Within IADMFR, Dr. Costa also made significant contributions. He served as a South American Regional Director from 2001 to 2015 and was a member of the current Trust Fund Committee. He often remarked on how his roles at IADMFR opened doors to international collaborations, institutional partnerships, and lasting friendships with colleagues around the world.

Claudio was widely admired for his intelligence, good humor, optimism, and remarkable memory. He was a gifted storyteller, and those who knew him remember his empathy, integrity, and kindness - qualities he extended generously to his students, friends, colleagues, and staff. His legacy will be forever cherished with love and pride. “Claudinho”, as he was affectionately known, remains a shining example and lasting inspiration for all of us. He is, and will always be, profoundly missed.

As a final tribute, we share his own words:

“A teacher must have the clarity to understand that they are not endowed with divine powers to change others, but the mortal wisdom to bring out the best that each person has to offer.”

We send our deepest condolences to his family, friends, and all who had the privilege of knowing him.

Our heartfelt thanks to Ana Luiza Esteves Carneiro, Daniela Miranda Richarte de Andrade Salgado, Edna Alejandra Gallardo-Lopez, Francisco Haiter Neto, Jefferson Xavier de Oliveira, and Luciano Augusto Cano Martins for their invaluable contributions to the writing of this obituary. We are also deeply grateful to all who shared their reflections and memories of Claudio’s life.

Sergio Lins de Azevedo Vaz

IADMFR Latin America Regional Director (Brazil)

Prof. Lin was trained at the University of Chicago under Prof. Bob Goepp (the president of AAOMR) during 1972-1975. After finishing his resident training in Oral Pathology and Oral Radiology, Prof. Lin became an instructor at the University of Chicago for one year, and then transferred to Chicago Loyola School of dentistry as an assistant professor for 3 years. In 1979, Prof. Lin went back to Taiwan as the Dean of School of Dentistry, Kaohsiung Medical University. He was the founder of Taiwan Academy of Oral & Maxillofacial Radiology (TAOMFR) and served as the first president for 3 years (2000-2003) as well as the fourth President of TAOMFR. In 2002, Prof. Lin held the 4th ACOMFR (Asian Congress) at Kaohsiung and the participants enjoyed a successful meeting with unforgettable memories. Additionally, being acting as the 21^st IADMFR president, Prof. Lin guided TAOMFR to host the 2017 IADMFR at Kaohsiung.

Finally, we would specially pay tribute to our mentor Prof. Lin whose remarkable contribution to OMFR. Under his excellent leadership and encouragement, we have kept abreast of the fast global upsurge in technology and knowledge within the field of OMFR and appear to go beyond the barren land of OMFR in Taiwan and now are regarded as one of the vital branches of dentistry in Taiwan. The innovative and revolutionary spirit of Prof. Lin will always take root in our mind and look forwards to the marvelous prospect of OMFR in Taiwan!

Peter Norman Hirschmann was born on 20^th November 1937, to Samuel and Phyllis (née Samuels) Hirschmann. The family lived in Orpington, Kent, where Peter’s father was a medical practitioner. The outbreak of war in 1939 led to his father being called up for national service, leaving Peter, his younger brother David and their mother for the duration. Peter was a bright boy and obtained a scholarship to Sevenoaks School, from where he went on to Guy’s Hospital in London to study dentistry.

After qualifying as a dentist in 1961, Peter worked in junior hospital posts at Guy’s. He obtained his Fellowship in Dental Surgery of the Royal College of Surgeons of England in 1965. He developed a research interest in Biochemistry and studied for a master’s degree, awarded in 1967, and was successful in obtaining a three-year Medical Research Council Junior Research Fellowship to continue his work in the Biochemistry field, part of which was spent at Harvard University. It was there that he met Denise Duffy, whom he married in 1968 in Cambridge, Massachusetts. Peter returned to England with Denise, in the hopes of developing his academic career further and managed to obtain a position at the Turner Dental School at the University of Manchester. This post combined teaching and clinical work in the X-ray department, but also gave Peter some opportunities to continue with his research with colleagues in the medical school. It was fortuitous that this job opened a pathway for him into Dental Radiology, which became the professional focus for the rest of his career.

In 1978, Peter crossed the Pennines to start a new position as a Consultant at The Dental Hospital at Leeds (subsequently Leeds Dental Institute), with honorary status at Leeds University to recognise his contributions to teaching. From this point on, his ambitions in biochemistry research had to be put aside. His job included the leadership role in Radiology and clinical diagnostic dental work in the “front door” Admissions department, where Leeds folk with toothache would queue up each morning, along with patients with more esoteric conditions. This was also where undergraduate students were taught the diagnostic method and dental “first aid”. Peter could be quite strict with students, and many former undergraduates will recall his exasperated voice saying, “it’s not an X-ray, young man; it’s a radiograph!”, but his insistence on systematic history taking and using investigations appropriately gave students an outstanding start to their careers.  Peter faced some challenges from senior clinicians, who were unfamiliar with a consultant colleague who could fearlessly challenge their X-ray requests, but he had the will to stand his ground and introduce more rational use of radiology. For many years, Peter organised lunchtime educational sessions at Leeds, in which he had the ability to appear sound asleep for much of the lecture, only then to ask the most pertinent questions.

Peter served on numerous national committees and working parties that set standards for the use of X-rays in dentistry. He served as President of the British Society of Dental and Maxillofacial Radiology (BSDMFR) twice, in 1989-91 and 2001-03, the latter period overlapping his retirement from clinical practice in 2001. Peter received the Diploma of Dental Radiology (DDR) of the Royal College of Radiologists in 1985, but he was awarded a Fellowship (FRCR) without examination in 1998 as recognition for his national status and work for the College.  Peter was also one of the Expert Panel that developed the European Guidelines on Radiation Protection in Dental Radiology, published in 2004, in which his wisdom was highly valued.

In the international context, Peter is best known for his work as Editor-in-Chief of “Dentomaxillofacial Radiology”, a post he held from 1988 to 2001. According to Peter, “In retrospect, I became an editor by happenstance” when a bid to print the journal from the University of Leeds Printing Service proved to be the cheapest option. This led the then Editor-in-Chief, Stuart White, to offer Peter the position of Associate Editor. Subsequently, when Stuart White stepped down from the post four years later, Peter was the best placed person to take on the main role.  Until then, the journal was biannual and had little recognition outside the IADMFR membership. During Peter’s term of office, he steered the journal on a course to being a “Journal of Head and Neck Imaging”, managing several unexpected changes of publisher before identifying a safe harbour with the British Institute of Radiology just as he retired.  Peter had a policy of “interventionist editing”, for example by meticulously checking manuscripts for use of English, and by asking perceptive questions of authors. One colleague (MR) has remarked that “Many times he asked, ‘do you mean this, or something else?’ In other words, he explained to us what we actually meant but had not considered, not even in our own language”. The challenges of the job would have exhausted most other people, but not him. The journal was obviously close to his heart, as was apparent when his former trainee (FC) came to Leeds for the first time to look at the job. She was told to look out for a man at the train station who, rather than having a carnation in his lapel, would be holding a copy of  “Dentomaxillofacial Radiology”.

While he built a successful career in Dental and Maxillofacial Radiology, Peter had a wide range of outside interests, particularly in the Arts, Music and Architecture. He had a love of ceramics and prints in particular. One of the authors of this obituary (KH) recalls being whisked away from a BSDMFR meeting in London so that Peter could share the delights of the Chelsea Art Fair. Peter was not only a consumer of the Arts, but he was often a Patron who provided both his time and money.  Notably, he was a member of the Victorian Society from 1990 to 2014, chairing the West Yorkshire Group for a period of time. He was involved with the Leeds Philosophical and Literary Society, The Leeds Library (2008-2013) and the Friends of Bradford Art Galleries and Museums. He was an enthusiastic attender of Opera North, of which he was a Patron, and also supported other vocal and choral works. The garden at the family home in Adel, Leeds, was immaculate. Later, when he and his wife downsized to an apartment in Harrogate, Peter took on the role of caring for the communal gardens.

Apart from his professional and cultural contributions, Peter was a stimulating and cultivated person with whom to spend time. As one colleague (MR) said, “he was a gentleman, but with a twinkle in his eye when we had differences of opinion”.  Peter Hirschmann died on Monday 19^th August 2024, and laid to rest in a quiet, green place in North Yorkshire ten days later. He leaves his wife Denise, their daughters Joanne and Catherine, and grandchildren Shoshana, Dalia, Oliver and Alexander, along with many friends and former colleagues, to mourn his loss.

Thanks also to others who contributed their thoughts, memories and information about Peter’s life, including Madeleine Rohlin, David Zeidman and, especially, Denise Hirschmann.

Many of you are familiar with Dr. Hollender and his remarkable achievements. After earning his PhD in 1965 at Gothenburg, Sweden, he became the first Professor and Chair of the Oral Radiology Department at the University of Gothenburg's School of Dentistry in 1968. He held various prestigious positions, including Visiting Professor at the UCLA School of Dentistry in Los Angeles, CA, and Vice Dean and Acting Dean of the School of Dentistry at the University of Gothenburg.

Dr. Hollender's expertise in dental and maxillofacial imaging earned him international renown as one of the foremost diagnostic oral and maxillofacial radiologists. He spent nearly 30 years as a full-time faculty member at the University of Washington, where his intellectual prowess and multilingual skills facilitated collaborations with professionals worldwide.

Throughout his career, Dr. Hollender received numerous research prizes and honorary memberships, showcasing his dedication to advancing the field. In 1985 he became IADMFR honorary member. He also held leadership roles in various professional organizations, including serving as President of the American Academy of Oral and Maxillofacial Radiology (AAOMR) and the American Board of Oral and Maxillofacial Radiology (ABOMR) in the 1990s.

Dr. Hollender's legacy extends beyond his professional achievements; he was admired for his integrity, sense of humor, kindness, and genuine concern for others. His passion for DMFR left a lasting impact on the field and those fortunate enough to know him. He will be deeply missed by the IADMFR community, and his legacy will continue to inspire future generations.

Dear colleagues and friends of IADMFR &​ EADMFR,

It is with great regret that we must inform you of the sudden death of our dear colleague, Laetitia Brocklebank, formerly Senior Lecturer in Oral Radiology at the University of Glasgow Dental School until her retirement, and latterly Honorary Senior Research Fellow.

Laetitia contributed enormously to Dental and Maxillofacial Radiology, undertaking important roles in both EADMFR and IADMFR and was a Past-President of BSDMFR. Amongst many achievements, she organised the very successful 13th ICDMFR in 2001 in Glasgow. While her professional activities have been invaluable to the specialty of Dental and Maxillofacial Radiology, it is her personal qualities that we remember with special fondness today. Laetitia supported so many students and colleagues in their professional and personal lives; her kindness and friendliness to others was exceptional. She was the life and soul of many ICDMFR congress social events. We will all miss her vivacity and good humour.

We send our deepest condolences to her family and especially to her partner and colleague, Professor Paul van der Stelt.
