LightBorn in Steamboat Springs, Colorado, USA, in 1942, Dr. Richard Wayne Light graduated from Johns Hopkins University School of Medicine in 1968. In 1972, during hisresidency in respiratory medicine at Johns Hopkins, he made a groundbreaking contribution by establishing the criteria for differentiating exudative from transudative pleural effusions. These criteria, now famously known as “Light’s criteria,” remain a cornerstone in clinical practice worldwide. This remarkable achievement marked the beginning of an illustrious and pioneering career dedicated to the study of pleural diseases, a field that became his lifelong passion.Dr. Light was not only a brilliant scientist but also a man of exceptional character. He was known for histireless work ethic, creativity and humility, as well as his genuine willingness to recognize and celebrate the achievements of others. He was a mentor and a friend to many, often sharing his wisdom through his famous “five keys to professional success”: be persistent, be organized, seek out win-win situations, adapt to the environment and, most importantly, “sleep with the right person,” a piece of advice he modeled in his loving partnership with his wife, Judi. Throughout his career, Dr. Light received numerous accolades, but he was particularly proud of being awarded an honorary doctorate by the University of Lleida in 2010.In his later years, Dr. Light faced the challenges of aging and declining health with remarkable courage and resilience. Tragically, his life was cut short by an accidental fall at home, silencing a mind of extraordinary brilliance. In his characteristic humility, he might have resisted such accolades, but it is undeniable that his name is synonymous with the study of the pleura. His contributions opened new frontiers in this vital area of medicine, inspiring generations of clinicians and researchers. In a final act of generosity, Dr. Light donated his body to science, a testament to his lifelong commitment to advancing medical knowledge.It may be a long time—if ever—before the world sees another pulmonologist of Dr. Light’s caliber, combining intellectual brilliance with profound humanity. Yet his legacy endures as his work continues to guide and inspire those who follow in his footsteps.Porcel JM. Dr. Richard W. Light (1942–2021). Arch Bronconeumol. 2021;57:51.
