compound. Izatt's work on molecular recognition was greatly influenced by his interaction with Pedersen. In Izatt's last visit with Pedersen prior to his death in 1988 he found a personal letter written by Pedersen that stated, “Most men achieve ‘Immortality’ through their progeny. I have no child of my own. Possibly, the crown ethers will serve, in a small way, to mark my footprint on earth” and Izatt believing this too shares Pedersen's message. Donald J. Cram Cram shared the 1987 Nobel Prize in Chemistry with Pedersen but expanding on Pedersen's monumental discovery in macrocyclic chemistry of crown ethers. Pedersen's work was in two-dimensional structures but Cram was able to synthesize similar molecules in three-dimensional space. Cram's synthesis of these three-dimensional molecules provided large gains in the production of enzymes made in labs as these structures have selectivity based on complementary structures. Jean-Marie Lehn Lehn was the other scientist who shared the Nobel Prize in Chemistry with Pedersen and was fundamental in starting the field of Supramolecular chemistry. Lehn's work specifically identified in his recognition for the Nobel Prize was in his work on cryptands. Miscellaneous research Although minimal research has been conducted on this compound, Pedersen observed that it had potential to work as a deactivator for copper. Nevertheless, it was the first of the many metal deactivators, which function by converting an inactive complex from an otherwise catalytic metal ion. Personal life Pedersen was married to Susan J. Ault in 1947 and the couple then moved to Salem, New Jersey, where they resided until Ault died on February 8, 1983, at 72 years old. 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. Shortly thereafter, he was awarded a medal for excellence by the DuPont Research Fellows. He died on 26 October 1989 in Salem, New Jersey. Legacy Following Pedersen's breakthrough in realizing his accidental product and structure of dibenzo-18-crown-6, huge advancements have been made in the fields of macrocyclic and supramolecular chemistry. Pedersen devoted the rest of his research career to studying these molecules and started one of the largest growths recently seen in a specific field of chemistry. This growth in Pedersen's field of work following his momentous discovery for macrocyclic compounds can be seen in the work of the 2016 Nobel Prize winner in Chemistry for molecular motors
