Robert William Wood (1868-1955) was an American physicist and inventor who made significant contributions to the field of optics and photography. He is best known for his work on ultraviolet photography, which allowed him to capture images of objects that were invisible to the naked eye.
Wood was born in Concord, Massachusetts, on May 2, 1868. He graduated from Harvard University in 1891 with a degree in physics. After graduation, he worked as a research assistant to Albert Michelson, who was one of the world’s leading physicists at the time.
In 1896, Wood was appointed as a professor of experimental physics at the University of Wisconsin. He remained at the university for the rest of his career, retiring in 1938.
Wood was a prolific inventor, and he held over 200 patents. His inventions included the Wood’s lamp, which is still used today to detect skin diseases and other medical conditions. He also invented the Wood’s filter, which is used to block out ultraviolet light.
In addition to his work on optics and photography, Wood also made significant contributions to the field of acoustics. He invented the Wood’s horn, which is a type of loudspeaker that is still used today.
Wood was a member of the National Academy of Sciences and the American Philosophical Society. He received the Franklin Medal from the Franklin Institute in 1938.
Wood died in Madison, Wisconsin, on August 11, 1955. He is considered to be one of the most important physicists of the 20th century.
Wood’s Work on Ultraviolet Photography
Wood’s work on ultraviolet photography began in the early 1900s. At the time, ultraviolet light was known to be invisible to the human eye. However, Wood discovered that he could capture images of objects that were invisible to the naked eye by using a special camera that was equipped with a Wood’s filter.
Wood’s ultraviolet photographs were groundbreaking. They allowed scientists to see the world in a new way. For example, Wood was able to use ultraviolet photography to capture images of the structure of atoms and molecules. He was also able to use ultraviolet photography to detect forgeries and to identify criminals.
Wood’s work on ultraviolet photography had a profound impact on the field of science. It opened up new possibilities for research and discovery.
Wood’s Other Inventions
In addition to his work on ultraviolet photography, Wood also invented a number of other important devices. These include:
- The Wood’s lamp: The Wood’s lamp is a type of ultraviolet lamp that is used to detect skin diseases and other medical conditions. The lamp emits ultraviolet light that causes the affected areas of the skin to glow.
- The Wood’s filter: The Wood’s filter is a type of optical filter that blocks out ultraviolet light. The filter is used in a variety of applications, including photography, microscopy, and medicine.
- The Wood’s horn: The Wood’s horn is a type of loudspeaker that is still used today. The horn is designed to amplify sound waves and to direct them in a specific direction.
Wood’s inventions have had a major impact on the fields of science, medicine, and engineering.
