Who is Charles J Pedersen?

Charles J Pedersen was an American organic chemist who did path-breaking work in describing methods of synthesizing crown ethers. For the same, he was awarded the Nobel Prize in Chemistry in 1987, which he shared with Donald J Cram and Jean Marie Lehn, the duo who took his work forward. Pedersen was the first DuPont scientist to won the Nobel Prize and also amongst the handful scientists who were bestowed with the award despite having no doctorate degree. Pedersen’s career as a scientist began when he studied chemical engineering at the University of Dayton in Ohio. He then completed his master’s degree from Massachusetts Institute of Technology. Though a bright student, Pedersen did not want to be supported by his father and thus dropped further studies to work. He found employment at DuPont Company, where he remained till his retirement. Unlike other scientists who usually reach the high point of their career mid-30s or early 40s, Pedersen’s magnum opus came after the age of 60. He was studying the effects of bi- and multidentate phenolic ligands on the catalytic properties of the vanadyl group, VO when he accidentally found unknown crystals of a by-product. Fascinated by the same, he studied further, little knowing that it would lead to a new chapter in chemistry. He discovered crown ethers, a molecule containing hydrogen, carbon and oxygen atoms. It was for this discovery that he was awarded the Nobel Prize.

Childhood & Early Life

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.

Career

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

By 1940, he had established his career as a chemist, excelling in the field of antioxidants. It was due to his scientific abilities and his know-how of the subject that he was appointed as a research associate in DuPont. It was the highest title that a DuPont researcher could obtain then. The post gave him the ability to choose his own projects.

In the late 1940s and early 1950s, Pedersen’s scientific interest became varied. He became interested in the photochemistry of some new phthalocyanine adducts and of quinoneimine dioxides. He developed polymerization initiators and also made some novel polymers.

In 1957, when Organic Chemicals Department at DuPont divided between two departments, Elastomers and Orchem, Pedersen chose the former. Thus, he worked at the Experimental Station where the Elastomers Department was based for the next ten years.

After a short stint of investigation in hydrocarbon polymers, in 1960, Pedersen returned to investigations in coordination chemistry. He studied the effects of bi- and multidentate phenolic ligands on the catalytic properties of the vanadyl group, VO.

It was while studying the complexes of vanadyl ion VO that one of the experiments led to the formation of an unexpected small quantity of unknown white crystals. Intrigued by the by-product, he studied it later identifying it as dibenzo18-crown-6, first crown ether.

He dedicated the last nine years of his life in the study of crown ethers, an unexplored region of chemistry. In 1967, he published two works which have become classics today. Through the work, he described the methods of synthesizing crown ethers (cyclic polyethers). The donut shaped molecules were the first in the series of extraordinary compounds that formed stable structures with alkali metal ions.

He retired from DuPont in 1969. Post retirement, he took a break from science to indulge in various hobbies including gardening, fishing, poetry and so on.

Major Works

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.

Awards & Achievements

In 1987, Pedersen was felicitated with the Nobel Prize in Chemistry for his work on the development and use of molecules with structure specific interactions of high sensitivity. He shared the prize with Donald Cram and Jean-Marie Lehn who expanded upon his original discoveries.

He also received a medal of excellence by the DuPont Company.

Personal Life & Legacy

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.

Trivia

Pedersen was one of the few people who were felicitated with a Nobel Prize in the science without having a Ph.D.
