Swann Chemical Company
The Swann Chemical Company was an American chemical company started by Theodore Swann, described by one historian as "a flamboyant Birmingham mogul and New South industrialist." Swann Chemical first operated a chemical manufacturing plant in Anniston, Alabama where PCBs Polychlorinated biphenyls (PCBs) are highly carcinogenic chemical compounds, formerly used in industrial and consumer products, whose production was banned in the United States by the Toxic Substances Control Act in 1979 and internationally by t ... were first made on an industrial scale after development of a new process under leadership of Theodore Swann. The plant was later bought by Monsanto Industrial Chemicals Co. in 1935. The plant, just west of Anniston, had around 1,000 employees. One historian wrote that, "In many ways, the spirit of Swann Chemical became the corporate culture of Monsanto."

Theodore Swann
Theodore Swann (September 6, 1886 – February 5, 1955) was an American industrialist and early leader of the chemical industry. He was described by one historian as "a flamboyant Birmingham mogul and New South industrialist." Hailing from east Tennessee, in his early working years, Swann was a power salesman for the Alabama Power Company. He established the Federal Phosphorus Company to produce concentrated phosphoric acid, mainly for use as a concentrated fertilizer, using a novel method to produce the acid from phosphate rock by heat treatment in an electric furnace. He later established the Swann Chemical Company, focused on production of PCBs for the emergent electrical industry. Swann Chemical Company operated a chemical manufacturing plant in Anniston, Alabama where PCBs were first made on an industrial scale after development of a new process under Swann's leadership. In 1920, Swann gave his engineers the challenge of creating a process by which PCBs, up to that time very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anniston, Alabama
Anniston is the county seat of Calhoun County in Alabama and is one of two urban centers/principal cities of and included in the Anniston-Oxford Metropolitan Statistical Area. As of the 2010 census, the population of the city was 23,106. According to 2019 Census estimates, the city had a population of 21,287. Named "The Model City" by Atlanta newspaperman Henry W. Grady for its careful planning in the late 19th century, the city is situated on the slope of Blue Mountain. History Civil War Though the surrounding area was settled much earlier, the mineral resources in the area of Anniston were not exploited until the Civil War. The Confederate States of America then operated an iron furnace near present-day downtown Anniston, until it was finally destroyed by raiding Union cavalry in early 1865. Later, cast iron for sewer systems became the focus of Anniston's industrial output. Cast iron pipe, also called soil pipe, was popular until the advent of plastic pipe in the 1960s. ...

Polychlorinated Biphenyl
Polychlorinated biphenyls (PCBs) are highly carcinogenic chemical compounds, formerly used in industrial and consumer products, whose production was banned in the United States by the Toxic Substances Control Act in 1979 and internationally by the Stockholm Convention on Persistent Organic Pollutants in 2001. They are organic chlorine compounds with the formula C12 H10−''x'' Cl''x''; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment. Because of their longevity, PCBs are still widely in use, even though their manufacture has declined drastically since the 1960s, when a host of problems were identified. With the discovery of PCBs' environmental toxicity, and classification as persistent organic pollutants, their production was banned by United States federal law in 1978, and by the Stockholm Convention on Persistent Organic Pollutants in 2001.

Monsanto
The Monsanto Company () was an American agrochemical and agricultural biotechnology corporation founded in 1901 and headquartered in Creve Coeur, Missouri. Monsanto's best known product is Roundup, a glyphosate-based herbicide, developed in the 1970s. Later the company became a major producer of genetically engineered crops. In 2018, the company ranked 199th on the Fortune 500 of the largest United States corporations by revenue. Monsanto was one of four groups to introduce genes into plants in 1983, and was among the first to conduct field trials of genetically modified crops in 1987. It was one of the top 10 US chemical companies until it divested most of its chemical businesses between 1997 and 2002, through a process of mergers and spin-offs that focused the company on biotechnology. Monsanto was one of the first companies to apply the biotechnology industry business model to agriculture, using techniques developed by biotech drug companies. In this business model, compani ...

Chemical Companies Of The United States
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...
