24th WOC Dresden, Germany
Olaf Gruss Science Medal
For more than four decades, Olaf Gruss has made outstanding contributions to orchid science as a taxonomist, researcher, author, and judge. After studying chemistry, he pursued a career as a teacher at a vocational college while simultaneously developing an internationally respected body of scientific work in orchid taxonomy. Since beginning his orchid studies in 1980, he has established internationally recognized expertise in the genera Phragmipedium, Paphiopedilum, and Phalaenopsis.
Olaf Gruss served for nearly twenty years as a volunteer member of the editorial team of Die Orchidee, the journal of the German Orchid Society. He is the author of numerous books and scientific papers published throughout Europe, North America, South America, and Asia. His research has significantly advanced the understanding of orchid taxonomy, nomenclature, and species diversity, particularly within the orchid floras of Southeast Asia and South America.
His work has focused especially on genera that had previously received comparatively little scientific attention, including Phragmipedium and later Phalaenopsis and Paphiopedilum. In addition to documenting species, he has made important contributions to the study and classification of orchid hybrids, recognising their significance in horticulture and breeding. Working independently and in collaboration with fellow researchers, Olaf Gruss has described numerous new orchid species, varieties, and forms across several important genera, including Paphiopedilum, Phalaenopsis, Coelogyne, and Phragmipedium.
He has also documented and published the breeding achievements of internationally renowned orchid breeders, including Henry Wallbrunn (USA), Marcel Lecoufle (France), and Franz Glanz (Germany), thereby preserving an important record of modern orchid hybridization.
Through an extensive body of published research and decades of dedicated scholarship, Olaf Gruss has made enduring contributions to orchid science. His work has benefited both professional botanists and orchid enthusiasts worldwide and has left a lasting legacy in the understanding, classification, and appreciation of orchids.
Mr. Philippe Lecoufle Horticulture Medal
Mr. Philippe Lecoufle is among Europe's most distinguished orchid growers, breeders, and exhibitors, and he has devoted his career to advancing orchid horticulture and promoting public appreciation of orchids worldwide. As the fourth-generation leader of Vacherot & Lecoufle, the world's oldest continuously family-operated orchid nursery, Mr. Lecoufle has carried on a tradition of excellence dating back to the nursery's founding in 1886.
After studying in England and receiving horticultural training in the United States and Germany, Mr. Lecoufle joined the family business in the 1980s and assumed its leadership in 1994. Under his direction, the nursery has remained at the forefront of orchid cultivation, breeding, and exhibition. The company played a pioneering role in developing orchid mericloning, helping make orchid cultivation more accessible worldwide. Its internationally recognized collections of Cattleyas and Paphiopedilums were designated National Collections by the French Conservatory of Specialized Vegetable Collections.
A renowned exhibitor and educator, Mr. Lecoufle has shared his expertise through workshops, publications, and major orchid exhibitions across Europe and at numerous World Orchid Conferences. His lifelong commitment to excellence has had a lasting impact on orchid horticulture and education worldwide.
Mr. Bernd Treder, Dr. Norbert Dank, and the Deutsche Orchideen-Gesellschaft (D.O.G.) Service Medal
The World Orchid Conference Trust recognizes Mr. Bernd Treder, Dr. Norbert Dank, and the Deutsche Orchideen-Gesellschaft (D.O.G.) for their exceptional service to the World Orchid Conference and the international orchid community. Founded in 1906, the D.O.G. is one of the world's largest orchid societies, representing thousands of amateur growers, professional horticulturists, and botanists dedicated to advancing orchid knowledge and appreciation.
Under the leadership of Mr. Treder, President of the D.O.G., the society secured the right to host the 24th World Orchid Conference in Dresden. Following the successful bid, a dedicated organizing committee was formed, with Dr. Dank serving as Project Manager and coordinating the planning and delivery of this major international event.
The organization of the 24th World Orchid Conference is particularly noteworthy because it has been undertaken entirely by an amateur orchid society. Despite having only two years to prepare, rather than the customary three, the organizing team has demonstrated remarkable commitment, professionalism, and collaboration in bringing the conference to fruition.
Through their dedication and leadership, Mr. Treder, Dr. Dank, and the D.O.G. Organizing Committee have made an outstanding contribution to the World Orchid Conference's continued success, vitality, and international spirit.
Dr. Dennis Whigham Conservation Medal
Dr. Dennis Whigham has been a pioneering leader in orchid conservation and research for more than three decades. As a Distinguished Emeritus Scientist at the Smithsonian Environmental Research Center, Dr. Whigham has integrated ecological research with practical conservation initiatives, transforming the protection of native orchids throughout North America.
Dr. Whigham's work has focused on elucidating the complex relationships among orchids, their habitats, and their mycorrhizal fungal partners. By integrating ecological science with conservation practice, he helped establish a comprehensive framework for orchid conservation and habitat management.
Among Dr. Whigham's most significant achievements was founding the North American Orchid Conservation Center (NAOCC), a collaborative network that now includes more than sixty institutional partners. Under his leadership, NAOCC has become a leading force in orchid conservation, research, education, and public outreach across the continent. IN 2025, Dennis was awarded the Philip E. Keenan Award from the American Orchid Society in recognition of the conservation efforts of his laboratory and their NAOCC collaborators.
Author of more than 250 peer-reviewed scientific papers, co-editor of eleven books, and co-author of the 2026 publication – Native Orchids of the United States and Canada, Dr. Whigham has inspired generations of researchers and conservationists. His dedication has profoundly and enduringly shaped orchid conservation worldwide.
