Charles John Pedersen (October 3, 1904 – October 26, 1989) was an American organic chemist best known for describing methods of synthesizing crown ethers. Crown ethers are heterocyclic Chemical compounds that consist of a ring containing several Ether groups Events 42 BC - First Battle of Philippi: Triumvirs Mark Antony and Octavian fight an indecisive battle with Caesar's Year 1904 ( MCMIV) was a Leap year starting on Friday (link will display calendar of the Gregorian calendar (or a Leap year starting on Events 740 - An Earthquake strikes Constantinople, causing much damage and death Year 1989 ( MCMLXXXIX) was a Common year starting on Sunday (link displays 1989 Gregorian calendar) The United States of America —commonly referred to as the Organic chemistry is a discipline within Chemistry which involves the scientific study of the structure properties composition reactions, and preparation Crown ethers are heterocyclic Chemical compounds that consist of a ring containing several Ether groups He was awarded the Nobel Prize in Chemistry in 1987. The Nobel Prize in Chemistry (Nobelpriset i kemi is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of Chemistry. Year 1987 ( MCMLXXXVII) was a Common year starting on Thursday (link displays 1987 Gregorian calendar) His Japanese first name was Yoshio (良男?). in modern times usually consist of a Family name ( Surname) followed by a Given name.
Born in Pusan, Korean peninsula to a Norwegian father and a Japanese mother, in 1904, Pedersen came to the United States in 1922 to study chemical engineering at the University of Dayton in Ohio.

As part of the Great Lakes region, Ohio has long been a cultural and geographical crossroads After receiving a bachelor's degree, he went to the Massachusetts Institute of Technology where he received a master's degree in organic chemistry. A bachelor's degree is usually an Undergraduate Academic degree awarded for a course or major that generally lasts for three four or in some cases and Although his professors encouraged him to pursue a Ph.D. at MIT, Pedersen decided to start his career instead, partially because he no longer wanted to be supported by his father.

In 1927, Pedersen began working at du Pont where he would remain for the next 42 years, retiring at the age of 65. E I du Pont de Nemours and Company (,) is an American chemical company that was founded in July 1802 as a Gunpowder mill by Eleuthère Irénée At du Pont, his work resulted in 25 papers and 65 patents. In 1967 he published two works that are now considered classics;[1] they describe the methods of synthesizing crown ethers (cyclic polyethers). Crown ethers are heterocyclic Chemical compounds that consist of a ring containing several Ether groups [2] The donut-shaped molecules were the first in a series of extraordinary compounds that form stable structures with alkali metal ions. Trends The alkali metals show a number of trends when moving down the group - for instance decreasing electronegativity increasing reactivity and decreasing melting and boiling An ion is an Atom or Molecule which has lost or gained one or more Valence electrons giving it a positive or negative electrical charge In 1987 he shared the Nobel Prize in Chemistry with Donald Cram and Jean-Marie Lehn for his work in this area; Cram and Lehn expanded upon his original discoveries. Donald James Cram (April 22 1919 &ndash June 17 2001 was an American chemist who shared the 1987 Nobel Prize in Chemistry with Jean-Marie Jean-Marie Lehn (born September 30, 1939) is a French Chemist.
Pedersen was diagnosed with myeloma in 1983, and though he was becoming increasingly frail, he traveled to Stockholm to accept the Nobel Prize in late 1987. Multiple myeloma (also known as MM, myeloma, plasma cell myeloma, or as Kahler's disease after Otto Kahler) is a type of ('stɔkhɔlm is Sweden 's Capital and its largest City. It is the site of the national Swedish government, the parliament, and the Shortly thereafter, he was awarded a medal for excellence by the du Pont Research Fellows.
