Ernest Dorsey, US physicist C016 / 4566
Noah Ernest Dorsey (1873-1959), US physicist and measurement scientist. Dorsey obtained his doctorate from Johns Hopkins University (1897). He joined the National Bureau of Standards (now the National Institute of Standards and Technology) in 1903, working there until his retirement in 1943. His main work was on radioactivity and X-rays. Here, he is examining the freezing point of water. Dorsey showed that impurities and chemicals in water can make it possible to cool samples (seen here) far below the standard freezing point before they froze. Photographed on 9 August 1938, at a laboratory in Washington DC, USA

EDITORS COMMENTS
This print captures the brilliant mind of Noah Ernest Dorsey, a renowned American physicist and measurement scientist. Taken in 1938 at a laboratory in Washington DC, USA, the image showcases Dorsey engrossed in his groundbreaking research on the freezing point of water. Dorsey's pioneering work focused on radioactivity and X-rays, but it was his investigation into the properties of water that truly captivated scientists worldwide. In this snapshot frozen in time, we witness Dorsey examining samples of water cooled well below its standard freezing point before solidification occurs. His revolutionary findings revealed how impurities and chemicals present in water can alter its behavior under extreme conditions. Having obtained his doctorate from Johns Hopkins University in 1897, Dorsey dedicated four decades to the National Bureau of Standards (now known as the National Institute of Standards and Technology). A true trailblazer in physical chemistry and metrology, he pushed boundaries with his meticulous experiments and unwavering dedication to scientific advancement. As we gaze upon this remarkable photograph, we are reminded not only of Dorsey's immense contributions to physics but also of the countless unsung heroes who have shaped our understanding of the world around us. This image serves as a testament to human curiosity and perseverance—a timeless reminder that progress is born from relentless exploration.
