Charles J Pedersen

Charles J. Pedersen tied the nuptial knot with Susan Ault in late 1940s. The couple settled in the town of Salem, New Jersey.

In 1983, he was diagnosed with myeloma. The condition left him increasingly frail and weak. He breathed his last on October 26, 1989 in Salem, New Jersey.

Charles J Pedersen was born on October 3, 1904, in Busan on the coast of south eastern Korea, to Breder Pedersen and Takino Yasui. His father was a Norwegian while his mother was Japanese.

At the age of eight, young Pedersen along with his family shifted to Nagasaki, Japan. Therein, he enrolled at a convent school. Two years later, he moved to Yokohama where he enrolled at an international school, St Joseph College.

Upon completing his early studies, Pedersen moved to United States where he studied chemical engineering at the University of Dayton in Ohio. He gained his Bachelor’s degree from the University of Dayton.

Following his bachelor’s degree, Pedersen gained admission at the Massachusetts Institute of Technology. From there, he received a master’s degree in organic chemistry. Despite being coaxed by his professor James F Norris, Pedersen did not pursue a doctorate degree and instead started a career because he did not want to remain a burden on his father anymore.

In 1927, Pedersen was employed by DuPont Company in Wilmington, Delaware upon the recommendation of his professor Norris. At DuPont, Pedersen was directed to research at the Chambers Work’s Jackson Laboratory by William S Calcott. He remained at DuPont for his entire 42 years career as a chemist, 32 years at Jackson Laboratory and last 10 years at the Experimental Station.

During his initial days as a scientist, Pedersen was asked to work on a series of typical problems. His earliest accomplishment was an improvement in the making of tetraethyl lead. The discovery had great commercial impact attached to it.

Later, he began to search for oil-solvable precipitants for copper. It was while working on the project that he found the first good metal deactivator for petroleum products, gasoline, oils and rubber.

It was following his discovery of the metal deactivator that Pedersen developed a great interest in the effects of various ligands on the catalytic properties of copper and the transition elements. As such, he continued to work in the field for several years.

Following his work on the catalytic properties of copper, he next found his interest in the oxidative degradation of the substrates that he was working on, such as petroleum products and rubber

The high point in Pedersen’s career came in 1960s when he discovered crown ethers, a family of ring-shaped molecules that have the ability to bind certain metallic atoms in the middle of the ring. Consequently, the metallic atoms could be released in organic compounds to incite a chemical reaction. Prior to the discovery of crown ethers, the possibility for bringing about chemical reactions in laboratories and creating chemical compounds by releasing metallic atoms in organic compounds was impractical.
