Wallace Carothers

On February 21, 1936, he married Helen Everett Sweetman of Wilmington, Delaware. A daughter, Jane, was born November 27, 1937, after the death of Carothers.

Carothers committed suicide on April 29, 1937. In 1937, his sister had died suddenly and this loss cast him into a depression, which ultimately resulted into his suicide.

Carothers was born on April 27, 1937 in Burlington, Iowa. Wallace carothers was the first scientist in the family.

His father, Ira Hume Carothers, taught at a country school. Later he entered the field of commercial education and for forty-five years engaged himself in that type of work as teacher and vice-president in the Capital City Commercial College, Des Moines, Iowa.

His mother, Mary Evalina McMullin of Burlington, Iowa, exerted a powerful influence and guidance in the earlier years of Carothers’s life.

Carothers was especially devoted to his sister, Isobel. Her death in January, 1936, was a shock to him and he was never able to reconcile himself completely to her loss.

Carothers was the oldest of four children. His education began in the public schools of Des Moines, Iowa, where his parents moved when he was just five. In 1914 he graduated from the North High School. As a growing boy he had zest for work as well as play. He enjoyed tools and mechanical things and spent much time in experimenting.

He entered Tarkio College, Tarkio, Missouri, in September, 1915, to pursue a scientific course, and simultaneously accepted a position of an assistant in the Commercial Department.

He continued in this capacity for two years and then was made an assistant in English, although he had specialized in chemistry from the time he entered college.

During the World War the head of the department of chemistry, Dr. Arthur M. Pardee, was called to another institution, and Tarkio College found it impossible to secure a fully equipped teacher of chemistry. Carothers, who previously had taken all of the chemistry courses offered, was appointed to take over the instruction.

Leaving Tarkio College in 1920 with his bachelor of science degree, he enrolled in the chemistry department of the University of Illinois where he completed the requirements for the master of arts degree in the summer of 1921.

His former instructor at Tarkio College, then head of the chemistry department at the University of South Dakota, desired a young instructor to handle courses in analytical and physical chemistry and was fortunate in securing Carothers for this position during the year, 1921-1922.

It was his discovery that it was possible to add hydrogen chloride to monovinylacetylene with formation of 2-chloro-i, 3-butadiene, called chloroprene. This substance is analogous structurally to isoprene but polymerizes several hundreds of times more rapidly and leads to a product much superior to all previously known synthetic rubbers. Carothers' work laid the foundation for the development by other chemists and by chemical engineers of the du Pont Company of the commercial product which has found wide industrial use and which is marketed as neoprene.

He investigated the means by which polymers structurally analogous to cellulose and silk could be prepared, and synthesized a large number. These materials constituted the first completely synthetic fibres with a degree of strength, orientation, and pliability comparable with natural fibres. This investigation led du Pont to set up a plant in Seaford, Delaware, which cost upwards of eight million dollars, for producing a new textile yarn to be known as nylon.
