Jay Keystone, Canada, 1995 – 1997

Jay KeystoneOn September 3, 2019, the travel and tropical medicine world lost a charismatic teacher and outstanding clinician. Many of us first met Jay at the Zurich Conference in 1988 where he displayed to the fledgling travel medicine community his uncanny ability to teach with humor and practicality. Much later, he transformed these methods into a well-known and much loved lecture on “Teaching teachers how to teach.”

Jay practiced medicine, taught, and lived his life on his own terms. Broad smiles and rumbles of laughter were typical during his presentations. Even while ill, he continued to put enormous time and energy into crafting new material for his lectures. Bawdy cartoons and politically incorrect statements punctuated his discourse, and while the occasional listener may have felt insulted, one realized that beneath this visage was someone who deeply loved his fellow man, no matter who they were, or from where they came.

The scientific community will miss this great professional. Jay was a Professor of Medicine at the University of Toronto, and for many years, the Director of the Tropical Medicine Unit at the Toronto General Hospital. Well known to have made hospital rounds on roller blades, “The General” was always his second home. One could find large stuffed animals and other mementos in his office from his many travels and from grateful patients. Later, Jay became the Director of the Toronto Medisys Travel Health Clinic and continued to see patients until just a few weeks prior to his death. Loved by his patients and respected by his fellow clinicians, Jay was always available for consultations. Many know the literature, but Jay was one of those rare physicians who was able to expertly and compassionately combine the science with the art.

As President of the ISTM from 1995-1997, he strengthened it with foresight and wisdom. He consolidated what the founders had initiated. All who practice travel medicine know “The Keystone,” the textbook in which he has been senior editor for all 4 editions. For his scientific contributions, he was awarded the Ben Kean Medal by the American Society of Tropical Medicine and Hygiene, and more recently was appointed to the Order of Canada. Earlier this year, Jay was awarded the Distinguished Fellow recognition of our Society. When he learned of the award, he gave a characteristic response, “What does it mean?....money, sex, fame?”

Above all, Jay was a family man. Some may recall his many lectures profiling his 5 children and their mother, Donna Keystone, referring to their escapades, and his desire to find them partners by tagging a phone number to their pictures. But the more recent highlight of his personal life occurred 10 years ago with his marriage to Margaret Keystone (nee Mascarenhas). Margaret, a native of Tanzania, and of Tanzanian and Goan background, made her way to Canada on her own in 1990. In 2008, while working, she and Jay met, finding both romance and friendship. There for support during Jay’s first bout with life threatening cancer requiring a bone marrow transplant, Margaret has been the strength that carried him forward. Together they shared the many joys of worldwide and armchair travel, as well as the intimacy of a private and loving home life.

Lastly, all those who had the opportunity to collaborate with Jay within the leadership of the Society, in its committees, meetings, updates, or elsewhere, know that we have lost not only an exceptional colleague and mentor, but also a dear friend, one whom we could turn to at any time for warmth, as well as invaluable and sound advice.

Frank von Sonnenburg, Germany, 2007 – 2009

Frank von Sonnenburg We are saddened by the death of Frank von Sonnenburg, MD, MPH, PhD, on August 21, 2020, after a relatively brief struggle with a brain cancer. Frank’s passing marks the loss of a loyal and longstanding ISTM leader and friend.

Frank was a Professor in Infectious Diseases and Tropical Medicine at the Ludwig-Maximilians-University of Munich. He had worked extensively in developing countries on a variety of infectious diseases projects, in public health at the WHO and elsewhere, and on vaccine clinical trials. Among many activities at ISTM, Frank served as CISTM7 Chair in Innsbruck, Austria in 2001, Secretary-Treasurer from 1997-2005, President from 2007-2009, and GeoSentinel Munich Site Director since 1995.

Frank led our Society in major achievements. He contributed greatly to organizing CISTMs in Europe that were not only scientific successes, but also convivial get-togethers and with his exceptional flair for numbers they provided a foundation for the financial success of the Society. He had a vision of a global Society in which peers from industrialized countries around the world would bring together colleagues from lower resource settings to develop travel medicine and travel health in their home countries.

Hans Nothdurft, medical school classmate and life-long good friend of Frank, remarked that Frank mellowed from his early-career radical viewpoints about health care, but continued to dedicate the focus of his work to vaccination as a crucial component of good health for all. Frank was a sincere and inspiring colleague.

Frank was also down-to-earth and keenly supported junior colleagues. As a fledgling travel medicine provider, Lin Chen had written to Frank to learn about Borrelia burgdorferi sensu lato in Europe. Although they had never met, Frank answered promptly and expertly with pertinent and valuable knowledge. In GeoSentinel, he constantly pushed for distributing reimbursements to his whole team and for different members on his team to co-author papers. Frank’s assertive but never arrogant nature, his willingness to respond to curiosity, and his support for junior colleagues have led to decades of fond memories for all who knew him.

Frank was a founding site director of GeoSentinel, making Munich one of the first sites outside North America, and from the start one of the largest and most diverse contributors to the network. Frank worked tirelessly from the beginning to update data collection, moving from using fax machines to web-based data entry. Frank later made a tremendous personal effort to more effectively integrate Munich’s huge and complex clinical operation with the Network. As a rare clinician with strong programming skills, he pioneered the use of electronic medical record templates to auto-populate the GeoSentinel database from the invaluable trove of clinical information gathered at his site – a task the rest of us still only dream about accomplishing one day. As co-members of the Data Quality Working Group since its inception, Michael Libman remembers with fondness innumerable days, meetings, meals, and wine-infused evenings dissecting, arguing, and laughing (sometimes quite hysterically) over data conundrums which always spilled over into stories and contemplation of work and life in general. Frank’s extensive clinical knowledge was essential in designing and improving the quality of our entire database. Michael notes that his devotion to GeoSentinel meant that his proposals and opinions were profuse, but always constructive and relevant, delivered with conviction and enthusiasm, and although we all debated a great deal, the result was always for the benefit of our projects.

All of us who spent time with Frank quickly realized that he had that rare balance between being opinionated, devoted, compassionate, and fun – a balance which pushed us all forward, while always enjoying the work and our time together. His joie-de-vivre was manifested by the extraordinary opening parties he organized at Innsbruck in 2001 and Budapest in 2009, which live on in ISTM lore. His compassion is recalled by David Freedman whose son was hospitalized in Munich a few years ago during a summer internship; Frank’s first words when David phoned him on a Sunday were, “don’t worry, I’m going to the hospital right now to check on things”. Frank exemplified what being part of the ISTM family means.

On behalf of ISTM leaders, we send our deepest sympathies to Frank’s wife Angelika and their sons. We remember warmly a passionate man, and with his heart always in the right place despite a few rough edges which were the evidence of his commitment. A man who greatly influenced travel medicine, GeoSentinel and global health. We will miss his expansive persona, his invaluable ideas, his drive and vision for ISTM and GeoSentinel, and the ever-present twinkle in his eyes!

In memory of Frank, you may wish to consider a donation to the ISTM Foundation.

Sincerely,
Lin Chen, ISTM President, with contributions from:

Alan J. Magill, United States of America, 2009 – 2011

Alan Magill One of Alan Magill's close friends, a doctor whom he had known since medical school, called me on Saturday, September 19th, to tell me that Alan had died that morning. He said that Alan had gone to a gym with his daughter to work out, and when they were driving home, a few blocks from their house, Alan suddenly pulled the car over to the curb, set the parking brake, and collapsed onto the steering wheel. His daughter, a recent college graduate, had the presence of mind—she was a Magill—to call 911, then pull Alan out of the car onto the street and start cardiopulmonary resuscitation. By chance, the first car to come upon the scene was driven by a doctor, who stopped to help. However, Alan never regained a cardiac rhythm.

I like to think about Alan in his last few seconds, suddenly aware that something was terribly wrong, but only thinking about his daughter's safety, steering the car skillfully to a stop—and setting the parking brake—before he lost consciousness. This seems so typical of Alan Magill—his presence of mind, coming up with a plan, and thinking only of others.

I first met Alan in 1994, when I invited him to speak at a Medicine for Adventure Travel conference in Jackson Hole, Wyoming. I didn't know him, and hadn't heard him speak, so I was nervous about putting him on the program, but he was well recommended by a friend of mine who knew him well. It always seemed so ironic, in retrospect, to have been hesitant to put Alan Magill on a program. He proved to be the clearest, warmest, most insightful speaker that one could hope to see. This was Alan's first foray into travel medicine, as he was a researcher for the U.S. army at the time, working in malaria and leischmaniasis.

Alan was an avid outdoors person, who raced bicycles in Europe while he was stationed there in the 1980s, skied for a U.S. army ski team, and climbed mountains, including ascents of Denali in Alaska, and a first ascent of a mountain in Tibet. He and his family often did long backpacking trips. He loved coming to Jackson Hole, and we went rock climbing together and road biking each time he came. When he was considering retiring from the army, he and his wife, Janiine, seriously looked into moving to Jackson Hole. Instead, Alan ended up taking a job at the Gates Foundation, as the head of their malaria eradication program. When he took that job, he had to choose between accepting a position as the head of infectious diseases at a major university, or the less certain path of working for a foundation. I urged him to go to the Gates Foundation where the potential for leaving a lasting legacy, befitting his great talents and potential, could be more easily realized.

Unlike a number of army researchers that I have worked with, Alan was active duty in the military, and was deployed to war zones in emergencies. I remember his vivid description to me of the massive array of invading forces that streamed across the desert from Kuwait into Iraq—which evoked Star Wars movies in his mind—when the U.S. invaded that country in 2003. Alan was there to counteract potential biologic warfare weapons that it was feared that the Iraqis might deploy.

In the wake of Alan's untimely death—he was only sixty-one years old—I've never seen an outpouring of such universally admiring praise, not just for his research ability, but for every aspect of his life and personality. Those who worked with him are in awe of his leadership ability, which will remain legendary: he quietly could steer any organization in the right direction, and inspire everyone with the attitude that problems can be solved. At meetings he was often the last to speak, and when he did he summed up the often contentious discussion with an insight that steered everyone in the right direction. Everything that I know about running meetings and trying to provide leadership I learned from Alan Magill.

Alan became the president of ISTM in 2009. He oversaw a difficult and somewhat painful change as the ISTM transitioned from operating out of an employee's home, to hiring an executive director and creating a designated ISTM office in Atlanta. Whom to hire, where to put the office (on which continent), and many other aspects were contentious from the beginning. Under Alan's watch, all of these problems got solved, one by one, and he never shied away from the difficult decision or the difficult phone call.

However, what I will remember most about Alan were his intellectual abilities. Unlike anyone else I knew, Alan would look at what we knew about travel or tropical medicine and ask how it was that we came to know that. He was not content to repeat what had been published in a textbook or journal. For example, Alan decided to look into how we treated P vivax malaria. It turned out that there were no studies to support the dosage and efficacy of primaquine; the duration of treatment had been based on the duration of the boat trip home from the Pacific at the end of World War II. Alan performed this historical evaluation on many different diseases, and it would be a fitting legacy to him if we could all remember to ask ourselves, “How do we know that this is true?” His example led me to discover that the entire calculation of the risk of hepatitis B in travelers was based on one study in missionaries to Africa in the 1950's.

Alan was devoted to his family above all, and they carried out many adventurous trips together. His wife, Janiine, was also in the U.S. army. Trained as a pediatrician, she supervised clinical trials for much of her career, then when they moved to Seattle, joined the Children's Hospital of the University of Washington as a pediatric oncologist. Alan's daughters are both college graduates, and pursuing careers that help other people. They were energetic children, and one time at a party at my house in Jackson Hole, someone came in to say that there were two young girls running around outside with burning sticks. Without even looking up, Alan said, “Those would be mine.”

I can't think of anyone else in my life who was so universally loved and admired. Alan never said anything bad about anyone, a trait that we could all learn from. He never tried to avoid the difficult decision or task. When he took on the challenge of trying to eliminate malaria from the world, one automatically assumed that if anyone could design such a program, it would be Alan. Sadly, I think it is genuinely true that the time frame for eliminating malaria in the world will probably be set back by the loss of his leadership and vision. He enthusiastically embraced the mission statement that I created for my presidency of ISTM, in that “the ideal form of travel medicine would be the kind that makes it unnecessary.” If there's no malaria in the world, there's no need to discuss malaria prophylaxis.

Alan treated everyone in his life the same way, with kindness and directness, whether they were patients, colleagues in other countries, friends, or family. There was never a dumb question around Alan. Everyone counted Alan as a friend, and as a resource for any difficult tropical medicine question. As the editor of Hunter's Tropical Medicine, Alan's knowledge of tropical medicine became even more encyclopedic. I called him last year to ask him about a patient who had been in Panama and had three weeks of fatigue, minor respiratory symptoms, and a fever every night at 7:00 p.m. He didn't readily know what he had, but he said, “You know, histoplasmosis was discovered in Panama. Has he been in a cave?” I went back to the patient and asked him, and he said that he had spent an hour exploring a cave looking for exotic insects. Histoplasmosis proved to be the diagnosis.

I want to share what Jay Keystone, another former president of ISTM, wrote to me upon hearing of Alan's death. Jay has recently been awarded the Order of Canada for his lifetime work in travel and tropical medicine, yet he credits Alan as being one of his greatest teachers: Alan was a brilliant teacher, the best that I have ever had the pleasure to learn from. He had the ability to simplify difficult concepts and to present them in a way that was both understandable and memorable. He will be missed, but his legacy as an outstanding educator, leader and caring human being will remain far beyond his too short life.

For all of us in travel or tropical medicine, we need to carry Alan's legacy forward as much as we can, remembering to treat everyone with kindness, to question what we know, to look things up, and to teach others when we can. I can't imagine anyone in medicine who was a more inspiring teacher and friend than Alan Magill.
