William Coblentz, US physicist C015 / 3286
William Coblentz (1873-1962), US physicist and astronomer with a spectroscope in his laboratory. Coblentz is best known for his work in infrared spectroscopy. He accepted a job at the National Bureau of Standards in 1905, remaining there for the rest of his career and heading the Radiometry Division for 40 years. Coblentz began studying elements and compounds before moving on to astrophysical research. His measurements of the absorption of infrared light by numerous substances lead to the ability to identify a molecule by this property. He also measured the infrared radiation from stars, planets and nebulae and measured the day and night time temperatures of Mars surface

EDITORS COMMENTS
This print showcases the brilliant mind of William Coblentz, an esteemed physicist and astronomer from the United States. Seated in his laboratory, Coblentz is seen engrossed in his work with a spectroscope, an instrument that played a crucial role in his groundbreaking research on infrared spectroscopy. Born in 1873 and passing away in 1962, Coblentz dedicated his entire career to the National Bureau of Standards. For four decades, he led the Radiometry Division with unparalleled expertise. His scientific journey began by studying elements and compounds before venturing into astrophysical exploration. Coblentz's pioneering measurements of infrared light absorption by various substances revolutionized molecular identification techniques. Moreover, he delved into measuring infrared radiation emitted by celestial bodies such as stars, planets, and nebulae. Notably, he even determined day and night temperatures on Mars' surface—an extraordinary feat for its time. This portrait captures not only Coblentz's immense contributions to physics but also highlights his dedication as a researcher and scientist. As an influential figure within the field of astrophysics during the early 20th century, Coblentz left an indelible mark on our understanding of radiant energy. Preserved by the Library of Congress/Science Photo Library archives, this image serves as a testament to William Coblentz's enduring legacy—a true luminary whose work continues to inspire generations of scientists worldwide.
