Robert Williams Wood (May 2 ,1868 –August 11 ,1955 ) was an Americanphysicist . He was a carefulexperiment er known for his many contributions tooptics including infrared andultraviolet photography , and the liquid mirror telescope. He discredited the purported phenomenon ofN rays .Klotz (1980)] He was also a writer ofscience fiction andnonsense verse .Life
Born in
Concord, Massachusetts , Wood attendedThe Roxbury Latin School Fact|date=February 2008 and earned his bachelor's degree atHarvard University . He studied atJohns Hopkins University ,University of Chicago , in Berlin and atMIT , although he never earned a doctorate. He taught at theUniversity of Wisconsin and then moved to Johns Hopkins.http://books.nap.edu/openbook.php?record_id=2201&page=441 Robert W. Woods, National Academy of Sciences Biographical Memoirs] He was professor of experimentalphysics at Johns Hopkins from 1901 until his death. [Anon.] (2001)]His fields of interest included
Raman spectroscopy ,field emission ,optics , and the manufacture ofdiffraction grating s. The optical effect belonging to diffraction grating known as Wood's anomaly is named after him.He discovered that the darkest area of the Moon in
ultraviolet light is the Aristarchus Plateau.Fact|date=August 2007 In 1909, Wood constructed the first practicalliquid mirror astronomical telescope, formed by spinning mercury so that it forms aparaboloid al shape, and investigated its benefits and limitations.

Though the discovery of
electromagnetic radiation beyond thevisible spectrum and the development of photographic emulsions capable of recording them pre-date Wood, he was the first intentionally to produce photographs with both infrared and ultraviolet radiation.Seabrook (1941)] He developed a filter,Wood's glass , that was opaque to visible light but was transparent to ultraviolet. He used it for ultraviolet photography but also suggested its use for secret communication.Williams & Williams (2002)] He was also the first person to photograph ultravioletfluorescence . He also developed a lamp,Wood's lamp , that radiated only ultraviolet.Fact|date=August 2007 The slightly surreal glowing appearance ofdeciduous tree s in infrared photographs is called the Wood effect.

In 1915, Wood co-authored a
science fiction novel , "The Man Who Rocked the Earth", withArthur Train . [Train & Wood (1915)] . He also wrote and illustrated a book of nonsense verse, "How to Tell the Birds from the Flowers".Wood died in
Amityville, New York . [Anon.] (1980)]Honors
