Joseph Regenstein
Joseph Regenstein (1889 – 1957) was probably the son of Martin R. (* 1874 in Pasing near Munich – 1909 in Chicago) and Theodore Regensteiners nephew.Gudrun Azar et al. 'Ins Licht gerückt. Jüdische Lebenswege im Münchner Westen'. München 2008, page 159-160 He was an American industrialist whose philanthropy benefited the city of Chicago, especially the University of Chicago, where the Regenstein Library is named in his memory. As head of Arvey Corp., Regenstein made many innovations in the paper, plastic and chemical fields. In 1931, Regenstein formed a business with his cousin, Julius Hyman, the Velsicol Chemical Corporation that manufactured several chlorinated insecticides including Dieldrin, Aldrin, Chlordane and Heptachlor which were the focus of Rachel Carson's book ''Silent Spring''. Regenstein and Hyman would later fall out when Hyman set up an independent business in Colorado to manufacture insecticides at the Rocky Mountain Arsenal. Numerous lawsuits follo ...

He had an older brother Siegfried (1866-1927) founder of the Automobilwerk Pasing near Munich. Theodore lost his mother age 3 and his stepmother Bertha, mother of Martin (?-1909 in Chicago) and Otto (1877-1941 in Kaunas) became a determining factor in bringing about his emigration in 1884 (he was age 15) to the USA. His father was the founder of the Albert Regensteiner Mechanische Schuhfabrik - Export - Engros in Pasing near Munich. Theodore R. established himself in Chicago where he joined the printing and publishing business. He is known for inventing the four-color lithographic press in 1894 when he requested an extra black plate in addition to the three traditional primaries for the printing of the Christmas issue of Century Magazine.

Rachel Carson
Rachel Louise Carson (May 27, 1907 – April 14, 1964) was an American marine biologist, writer, and conservationist whose influential book ''Silent Spring'' (1962) and other writings are credited with advancing the global environmental movement. Carson began her career as an aquatic biologist in the U.S. Bureau of Fisheries, and became a full-time nature writer in the 1950s. Her widely praised 1951 bestseller '' The Sea Around Us'' won her a U.S. National Book Award, recognition as a gifted writer and financial security. Her next book, ''The Edge of the Sea'', and the reissued version of her first book, '' Under the Sea Wind'', were also bestsellers. This sea trilogy explores the whole of ocean life from the shores to the depths. Late in the 1950s, Carson turned her attention to conservation, especially some problems she believed were caused by synthetic pesticides. The result was the book ''Silent Spring'' (1962), which brought environmental concerns to an unprecedente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rocky Mountain Arsenal
The Rocky Mountain Arsenal was a United States chemical weapons manufacturing center located in the Denver Metropolitan Area in Commerce City, Colorado. The site was completed December 1942, operated by the United States Army throughout the later 20th century and was controversial among local residents until its closure in 1992. Much of the site is now protected as the Rocky Mountain Arsenal National Wildlife Refuge. History After the attack on Pearl Harbor and the United States entered World War II, the U.S. Army began looking for land to create a chemical manufacturing center. Located just north of Denver, in Commerce City and close to the Stapleton Airport, the U.S. Army purchased . The location was ideal, not only because of the proximity to the airport, but because of the geographic features of the site, it was less likely to be attacked. The Rocky Mountain Arsenal manufactured chemical weapons including mustard gas, napalm, white phosphorus, lewisite, chlorine gas, and sar ...

Silent Spring
''Silent Spring'' is an environmental science book by Rachel Carson. Published on September 27, 1962, the book documented the environmental harm caused by the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly. In the late 1950s, Carson began to work on environmental conservation, especially environmental problems that she believed were caused by synthetic pesticides. The result of her research was ''Silent Spring'', which brought environmental concerns to the American public. The book was met with fierce opposition by chemical companies, but it swayed public opinion and led to a reversal in U.S. pesticide policy, a nationwide ban on DDT for agricultural uses, and an environmental movement that led to the creation of the U.S. Environmental Protection Agency.Paull, John (2013"The Rachel Carson Letters and the Making of Silent Spring", Sage Open, 3 ( ...

Heptachlor
Heptachlor is an organochlorine compound that was used as an insecticide. Usually sold as a white or tan powder, heptachlor is one of the cyclodiene insecticides. In 1962, Rachel Carson's ''Silent Spring'' questioned the safety of heptachlor and other chlorinated insecticides. Due to its highly stable structure, heptachlor can persist in the environment for decades. In the United States, the Environmental Protection Agency has limited the sale of heptachlor products to the specific application of fire ant control in underground transformers. The amount that can be present in different foods is regulated.Robert L. Metcalf "Insect Control" in ''Ullmann’s Encyclopedia of Industrial Chemistry'', Wiley-VCH, Weinheim, 2002. Synthesis Analogous to the synthesis of other cyclodienes, heptachlor is produced via the Diels-Alder reaction of hexachlorocyclopentadiene and cyclopentadiene. The resulting adduct is chlorinated followed by treatment with hydrogen chloride in nitromethane i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chlordane
Chlordane, or chlordan, is an organochlorine compound that was used as a pesticide. It is a white solid. In the United States, chlordane was used for termite-treatment of approximately 30 million homes until it was banned in 1988. Chlordane was banned 10 years earlier for food crops like Maize, corn and citrus, and on lawns and domestic gardens.Robert L. Metcalf "Insect Control" in ''Ullmann’s Encyclopedia of Industrial Chemistry'', Wiley-VCH, Weinheim, 2002. Like other chlorinated cyclodiene insecticides, chlordane is classified as an persistent organic pollutants, organic pollutant hazardous for human health. It is resistant to degradation in the environment and in humans/animals and readily accumulates in lipids (fats) of humans and animals.Agency for Toxic Substances & Disease Registry (ATSDR). Toxic Substances Portal: Chlordane. Last updated September, 2010 [online]. Available at URL: http://www.atsdr.cdc.gov/substances/toxsubstance.asp?toxid=62 Exposure to the compoun ...

Aldrin
Aldrin is an organochlorine insecticide that was widely used until the 1990s, when it was banned in most countries. Aldrin is a member of the so-called "classic organochlorines" (COC) group of pesticides. COCs enjoyed a very sharp rise in popularity during and after The Second World War. Other noteworthy examples of COCs include DDT. After research showed that organochlorines can be highly toxic to the ecosystem through bioaccumulation, most were banned from use. It is a colourless solid. Before the ban, it was heavily used as a pesticide to treat seed and soil. Aldrin and related "cyclodiene" pesticides (a term for pesticides derived from Hexachlorocyclopentadiene) became notorious as persistent organic pollutants.Robert L. Metcalf "Insect Control" in Ullmann’s Encyclopedia of Industrial Chemistry" Wiley-VCH, Weinheim, 2002. Structure & Reactivity The structure formula of aldrin is C12H8Cl6. The molecule has a molecular weight of 364.896 g/mol. The melting point of aldrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
