Ellsworth Dougherty
Ellsworth C. Dougherty (July 21, 1921 – 1965) was a biologist who was first to study the nematode worm '' Caenorhabditis elegans'' in the laboratory, with Victor Nigon Victor Marc Nigon (born 11 October 1920 in Metz, France, died 5 July 2015) was a biologist who was first to study the nematode worm ''Caenorhabditis elegans'' in the laboratory, with Ellsworth Dougherty, in the 1940s. Jean-Louis Brun, a student of ..., in the 1940s. He did most of his studies and medical work in California. Tributes Mount Dougherty is a mountain range in Antarctica named after Ellsworth Dougherty. The specific epithet given to the nematode species '' Caenorhabditis doughertyi'' is also a tribute to E. Dougherty.

Caenorhabditis Elegans
''Caenorhabditis elegans'' () is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek ''caeno-'' (recent), ''rhabditis'' (rod-like) and Latin ''elegans'' (elegant). In 1900, Maupas initially named it '' Rhabditides elegans.'' Osche placed it in the subgenus ''Caenorhabditis'' in 1952, and in 1955, Dougherty raised ''Caenorhabditis'' to the status of genus. ''C. elegans'' is an unsegmented pseudocoelomate and lacks respiratory or circulatory systems. Most of these nematodes are hermaphrodites and a few are males. Males have specialised tails for mating that include spicules. In 1963, Sydney Brenner proposed research into ''C. elegans,'' primarily in the area of neuronal development. In 1974, he began research into the molecular and developmental biology of ''C. elegans'', which has since been extensively used as a model organism. It was the first mult ...

Victor Nigon
Victor Marc Nigon (born 11 October 1920 in Metz, France, died 5 July 2015) was a biologist who was first to study the nematode worm ''Caenorhabditis elegans'' in the laboratory, with Ellsworth Dougherty, in the 1940s. Jean-Louis Brun, a student of Nigon, continued experiments on the 'Bergerac' variety of ''C. elegans''. The specific epithet given to the nematode species ''Caenorhabditis nigoni'' is a tribute to Victor Nigon. Victor Nigon has filed for some patents to protect their inventions, which have already been granted by the United States Patent and Trademark Office (USPTO).

Mount Dougherty
Mount Dougherty is a mountain, high, between Mount Sandved and Mount Cara on the main north–south ridge in the northern part of the Queen Elizabeth Range. It was mapped by the United States Geological Survey from tellurometer surveys and Navy air photos, 1960–62, and was named by the Advisory Committee on Antarctic Names for Ellsworth C. Dougherty, a United States Antarctic Research Program biologist at McMurdo Sound McMurdo Sound is a sound in Antarctica. It is the southernmost navigable body of water in the world, and is about from the South Pole. Captain James Clark Ross discovered the sound in February 1841, and named it after Lt. Archibald McMurdo ..., 1959–60 and 1961–62. References Mountains of the Ross Dependency Shackleton Coast {{ShackletonCoast-geo-stub ...

Caenorhabditis Doughertyi
''Caenorhabditis doughertyi'' is a species of nematodes in the genus ''Caenorhabditis''. Prior to 2014, it was referred to as ''C. sp. 10'' JU1333 wild isolate was collected from rotting cacao fruits in Kerala, India in 2007.

History Of Research On Caenorhabditis Elegans
The nematode worm '' Caenorhabditis elegans'' was first studied in the laboratory by Victor Nigon and Ellsworth Dougherty in the 1940s, but came to prominence after being adopted by Sydney Brenner in 1963 as a model organism for the study of developmental biology using genetics. In 1974, Brenner published the results of his first genetic screen, which isolated hundreds of mutants with morphological and functional phenotypes, such as being uncoordinated. In the 1980s, John Sulston and co-workers identified the lineage of all 959 cells in the adult hermaphrodite, the first genes were cloned, and the physical map began to be constructed. In 1998, the worm became the first multi-cellular organism to have its genome sequenced. Notable research using ''C. elegans'' includes the discoveries of caspases, RNA interference, and microRNAs. Six scientists have won the Nobel prize for their work on ''C. elegans''. Early research ''C. elegans'' was first described in 1900 by Émile Maupas ...
