Jack Dunn Trop, born on May 17, 1900, in the bustling city of New York, was the only son in a large family of seven children. In 1928, he married Sylvia Warshawski, and together they created a family, later welcoming their beloved son, Jules Trop, into the world.

Trop began his career in the motion picture industry in 1920 and quickly made a name for himself as a writer, director, and producer. Throughout his career, he produced several notable films, including Keep Going (1926), Riders of Vengeance (1928), Outlaw’s Highway (1934), Chloe, Love is Calling You (1934), In Old Mexico (1938), Pride of the West (1938), Bar 20 Justice (1938), Heart of Arizona (1938), Heritage of the Desert (1939), Silver on the Stage (1939), Old MacDonald’s Farm (1951), and The Secret of Magic Island (1964). He is perhaps best remembered for his significant role in creating the iconic Hopalong Cassidy series, a milestone in film history that resonates with audiences today.

At just 27 years old, Trop found himself grappling with severe health issues that seemed insurmountable. He became determined to understand what was happening within his body. However, each visit to a physician only deepened his confusion. One doctor diagnosed him with sinusitis; another suggested rheumatism. Others pointed towards flat feet, chronic catarrh, constipation, or even heart disease. 

Caught in this cycle of contradictory medical opinions, Trop felt increasingly trapped and uncertain about his future. Each appointment left him more disheartened as if his world was closing in around him. The relentless ambiguity and lack of definitive answers bore down on him, leading him into a profound state of despair that seemed endless. His journey highlighted the urgent need for clarity in healthcare, making it clear that understanding one’s health is vital not just for recovery but for a brighter, hopeful future.

In his book You Don’t Have to Be Sick!, Trop reflects on his experience with brutal honesty, noting that he was fortunate they didn’t remove more of him. They did, however, remove his tonsils, excise cartilage from his nose, and prescribe him heavy doses of drugs. But, instead of finding relief, his condition only worsened. This cycle of treatments that led to no discernible improvement deepened his frustration and yearning for answers, driving him to search desperately for clarity, healing, and, above all, hope.

Through the introduction of a friend, Trop embarked on a transformative health journey under the care of Dr. H. William Baum, a naturopath and physiotherapist to whom he would forever be deeply grateful. For nearly two years, Trop benefited from Dr. Baum’s holistic and comprehensive approach to healing. His treatment regimen included two colonic irrigations per week, consistent chiropractic adjustments, and a diverse array of therapies designed to revitalize both body and mind. These therapies ranged from electrical applications and invigorating massages to soothing steam sessions with hot water and Epsom salts, as well as refreshing ice-cold hip baths and sitz baths.

In addition to these physical treatments, Trop adopted a transformative dietary plan under Dr. Baum’s guidance. This diet eliminated refined foods and significantly reduced concentrated starches while including meat. Other therapies included diathermy, infrared heat, and exposure to artificial sun lamps—all aimed at accelerating his recovery, enhancing his vitality, and restoring his overall well-being. This comprehensive and personalized approach was pivotal in Trop’s healing process, offering him not just physical relief but also a renewed sense of hope and well-being.

Trop avidly immersed himself in the transformative works of renowned health pioneers such as William Howard Hay, Friedrich Eduard Bilz, Dr. Vincenz Prießnitz, Adolph Just, Dr. Benedict Lust, Bernarr Macfadden, and Dr. John Harvey Kellogg. Their groundbreaking ideas fueled his enthusiasm and deepened his commitment to holistic health. He became an ardent supporter of various health lecturers who, through their wisdom and teachings, inspired countless others to adopt a healthier lifestyle.

Thanks to Dr. Baum’s rigorous regimen, Trop saw significant improvements in his health, primarily due to the profound lifestyle changes he implemented. He reduced his intake of refined foods, committed to regular exercise, and embraced the restorative power of sunshine, rest, and sleep. These changes, along with his dedication to Dr. Baum’s guidance, were instrumental in his recovery.

However, despite these positive shifts, Trop faced challenges in fully embracing the naturopathic approach. He struggled with quitting smoking and eliminating meat products from his diet, even as he adopted other health principles. These lingering obstacles underscored the complexity of his journey, but they also reflected his ongoing dedication to improving his health, even when faced with personal challenges.

Trop lost around forty pounds, making significant strides toward better health and well-being. Along this transformative journey, he crossed paths with Dr. Benedict Lust, who introduced him to an unconventional treatment: sitting in ice-cold water. “It stimulates the bowels,” Dr. Lust claimed, offering it as a remedy for digestive health. While Trop initially embraced this idea, he later came to believe that this emphasis on “curing” the body through intense, stimulating methods was a key reason why nature cure practitioners and natural hygienists often diverged in their approaches to health.

As Trop began to distance himself from traditional allopathic medicine, he pursued further education in naturopathy and nature cure. He attended and eventually graduated from reputable naturopathic and nature cure schools, gaining valuable insights into holistic health practices. However, he found these programs, much like the broader naturopathic movement, still caught in a cycle of stimulation—focused on quick fixes rather than foundational, sustainable health principles. Trop concluded that actual progress in health care could only be achieved by embracing the core principles of natural hygiene, which emphasize balance, prevention, and the body’s innate ability to heal without reliance on artificial stimuli.

In 1942, Trop made a pivotal decision to further support his newfound commitment to health by opening a health food store, The Vitamaster, on West 50th Street in New York City. This became more than just a business venture—it was a turning point in his wellness journey. Here, Trop met Symon Gould, a regular customer and second-hand book dealer, who introduced him to the powerful concept of Natural Hygiene. Symon’s collection of books provided Trop with invaluable resources, sparking his deep interest in this holistic approach to health.

Trop eagerly immersed himself in the works of influential health pioneers such as Rev. Dr. Sylvester Graham, Dr. Isaac Jennings, Dr. Russell Thacker Trall, Dr. William Alcott, Dr. Thomas Nichols, Mary Gove Nichols, and Dr. Felix Oswald.  These figures laid the groundwork for many of the principles he came to embrace. 

Among them, Dr. Herbert M. Shelton stood out as a particularly exceptional modern interpreter of natural hygiene. Shelton’s profound insights and clear articulation of the principles of health and healing have significantly shaped contemporary understanding in the field, making him a key influence on Trop’s evolving approach to wellness.

Through these writings, Trop began to understand and embrace the comprehensive health principles promoted by Natural Hygiene. Adopting a vegetarian lifestyle was one of the first steps in his transformation. Over time, he fully integrated the life-enhancing practices of Natural Hygiene into his daily routine, setting him on a path toward optimal health and well-being.

In 1944, Jack Dunn Trop and Irving Davidson formed a small yet passionate group that met regularly in the office of an insurance agent named Norman Osborn. They called themselves the New York Natural Hygiene Society. While their membership was modest, their commitment to the principles of Natural Hygiene was unwavering. One day, during a conversation, Trop proposed an exciting idea to Irving: why not expand their efforts and create a national organization? He was inspired by the memory of a national Natural Hygiene Society that had existed in the 1840s, and he saw an opportunity to revive and build upon that legacy.

The two of them drafted a letter to Dr. Herbert M. Shelton, the leading modern advocate of Natural Hygiene, suggesting the creation of a national society. Shelton responded enthusiastically, offering his expertise and financial support: “Okay. If you do, I’ll finance it and manage all the organizational tasks.” This marked a pivotal moment in the movement’s history, setting the stage for establishing a more extensive and influential network dedicated to the principles of Natural Hygiene. With Dr. Shelton’s guidance and resources, their vision began to take shape, laying the foundation for a national movement that would inspire countless individuals to embrace healthier, more holistic lifestyles.

The core goals and aspirations of the American Natural Hygiene Society were rooted in education rather than in healing or the practice of medical arts. The Society’s primary mission was to teach individuals how to live healthily and naturally. Jack Dunn Trop often suggested that a more fitting name for what Natural Hygiene truly represents would be “Normal Living.” He believed the term “Hygiene” could easily mislead people into thinking it was limited to basic health practices, such as dental care or personal cleanliness. In his view, this did not fully capture the breadth of the movement’s emphasis on holistic health and natural living.

Trop’s argument for a more precise nomenclature reflected a more profound vision for the American Natural Hygienic Society’s role in the US. This vision came to fruition in 1999 when the board voted to change the name to the National Health Association, better aligning with the Society’s commitment to holistic education and the promotion of overall well-being. The name change not only clarified the purpose of the organization but also reinforced its dedication to guiding individuals toward healthier, more balanced lives through education rather than simply focusing on health practices in isolation.

Throughout his career, Jack Dunn Trop envisioned creating influential films highlighting the transformative benefits of fasting, believing it would deeply resonate with audiences. In collaboration with R. J. Cheatham, he devised an ambitious plan to produce a series of six films, each focused on a fundamental aspect of health—rest, exercise, sunshine, the mind, fasting, and the significance of food. Their vision was to offer viewers a comprehensive exploration of these essential topics, empowering them to adopt healthier lifestyles.

However, despite their passion and dedication, funding proved to be a constant obstacle, preventing these impactful projects from coming to fruition. Although they could not bring the films to life, Trop’s commitment to spreading the principles of Natural Hygiene and holistic health remained unwavering, and his vision for educating the public through film continued to inspire those around him.

However, one of Trop’s most remarkable achievements was the creation of The Greatest Adventure. This groundbreaking historical film chronicled the inspiring stories of individuals whose lives were transformed through the principles of Natural Hygiene. The film, which quickly became a classic, was the first to focus on health and wellness in a profound and cinematic way. Drawing upon insights from his influential book Help Yourself to Health, the movie The Greatest Adventure honored the pioneering work of health reformers such as Dr. Russell Thacker Trall, Dr. Isaac Jennings, and Reverend Dr. Sylvester Graham. The film’s compelling narrative captured the universal human quest for health, vitality, and happiness, resonating deeply with audiences who sought inspiration and guidance to health in their own lives.

Trop believed that the ideal hygienist embodied lean strength, agility, and flexibility—traits that symbolize physical health, an open mind, compassion, self-love, profound love for humanity, and genuine tolerance. He argued that these characteristics were essential for achieving true health, which he defined as the purity of mind, body, and soul, all striving toward the highest levels of wellness. Trop often drew upon the wisdom of the Bible, which clearly articulates this principle: “Honor the temple which is thy body and keep it holy.” To Trop, embracing these values was more than just a personal choice—it was a path to holistic well-being, a way of living that nurtured the whole person, fostering balance and harmony in every aspect of life.

Trop firmly believed that we should avoid getting trapped in the mindset of merely combating diseases or relying too heavily on medical terminology. While he acknowledged the importance of caring for those suffering and needing help, he argued that such concerns should be distinct from the core principles of Natural Hygiene.

At the heart of Natural Hygiene is the understanding that health begins with removing the root causes of illness. True health can be restored if the body’s vital forces remain intact and are not irreversibly depleted. This philosophy is about treating symptoms and empowering the body to heal by addressing the underlying imbalances. Trop emphasized that this approach—focused on prevention and nurturing vitality—must be the foundation of what we teach, practice, and advocate in the ANHS to pursue holistic wellness.

Trop had the honor of serving as president of the ANHS from 1981 to 1982. Still, he often reflected that the most rewarding and enlightening experiences of his journey with Natural Hygiene came from attending the annual conventions. These gatherings offered a rare and profound opportunity to immerse oneself fully in the principles of Natural Hygiene. Trop cherished the chance to experience meals that exemplified the ideal human diet, connect with a global community of like-minded individuals, attend thought-provoking classes and lectures from esteemed educators, and build new friendships and long-lasting relationships.

In Trop’s view, the conventions provided an unparalleled week of striving for health and normalcy, where the heart and mind united in transformative ways. The sense of camaraderie, inspiration, and shared commitment to wellness was something he deeply valued. Remarkably, he only missed a few conventions in his entire life—a testament to the immense significance he placed on these unforgettable, life-enhancing experiences. For Trop, these gatherings were not just events but milestones in a lifelong journey toward holistic well-being.

Trop was an exceptionally prolific writer who made lasting contributions to the field of health through his work as the Editor of Health Science magazine from 1980 to 1985. His influence extended beyond his editorial role, with his notable book A Gift of Love: The Hopewood Story (1971), which compellingly chronicles the inspiring journey of 86 war orphans. Under the care of L.O. Bailey and Madge Cockburn, these children thrived on a natural diet, illustrating the transformative power of nutrition and holistic care. For over a decade, the adult children from the Hopewood Youth Development Center enriched ANHS conventions with their heartfelt testimonials, serving as living examples of the book’s message.

In addition to A Gift of Love, Trop wrote several impactful works, including Please Don’t Smoke in Our House and You Don’t Have to Be Sick. Trop reinforced his unwavering commitment to promoting health, wellness, and natural living through these books. His writings were not just informative but also a call to action, urging readers to take charge of their health and well-being. Trop’s literary legacy continues to inspire and guide those on the path to holistic health.

Trop’s contributions to Natural Hygiene, health education, and the wellness movement were immeasurable.

Jack Trop’s contributions to the Society were truly immeasurable. He was a tireless advocate for a life of balance, promoting not just physical health but mental and emotional well-being as well. He viewed health as the purity of the mind, body, and soul, with each element working harmoniously to achieve optimal wellness. A co-founder of ANHS, Jack wore every conceivable hat—and did so with remarkable dedication and excellence. Over more than four decades, he managed numerous annual conferences, served on the Board of Directors and Executive Committee, and held a term as President. He also co-founded and chaired the Natural Hygiene Press, co-edited the Society’s best-selling Fasting Can Save Your Life, and authored his own influential primer, You Don’t Have to Be Sick. A dynamic presence at conferences and seminars, Jack was a frequent lecturer, a prolific contributor to ANHS journals, and a long-time editor of Health Science magazine. His film, The Greatest Adventure, introduced thousands to the principles of Natural Hygiene.

More than his titles and achievements, Jack lived the lifestyle he championed. His commitment went far beyond dietary discipline—though he followed a strict vegetarian diet without exception. Those who knew him well recall that, for Jack, food was almost an afterthought. His real focus was living a life of balance, integrity, and purpose, embodying the very essence of Natural Hygiene in both word and deed.

Jack Dunn Trop passed on May 16, 1992, at the age of 91. His teachings and legacy continue to inspire generations of health enthusiasts and practitioners who are dedicated to living in alignment with nature.

HYGIENE – THE TRUE SCIENCE OF HEALTH

Quote: The dictionary gives us the following definitions: 

SCIENCE: Knowledge gained and verified by exact observation and correct thinking. 

HYGIENE: The science that relates to the preservation of Health.

Medicine, accurately defined embraces all of the arts of healing. The allopaths, who are generally known as medical doctors, use drugs as their mainstay. They have arrogantly allocated to themselves the all embracing word “medicine.. However, an examination of the principles of the father of medicine, Hippocrates, indicates that the drugging fraternity have travelled far afield from the path that he espoused, but that the Hygienists have hewn ever more closely to the Hippocratic oath. The drug healers are merely a small decaying branch of the healing arts which has for almost two thousand years tried to overshadow the true tree of health, which is Hygiene.

Hygiene teaches the Law of Life. It uses ONLY those agencies in disease which the body needs at all times to maintain itself in health. It has no miracle medicines. However, it does have Eight Magic Watchwords Of Health.

These Eight keys that unlock the door of most of what makes life worth-while are not mysterious and for the most part they cost little. Here they are, AIR, WATER, FOOD, REST, SLEEP, EXERCISE, FASTING and THOUGHT.

The proper use of these eight elements constitutes the science of hygiene.

From the 1949 Conference Program
