Jerrold Meinwald(January 16, 1927 – April 23, 2018) was an Americanchemistknown for his work onchemical ecology,a field he co-founded with his colleague and friendThomas Eisner.He was a Goldwin SmithProfessor Emeritus of ChemistryatCornell University.He was author or co-author of well over 400 scientific articles. His interest in chemistry was sparked by fireworks done with his friend Michael Cava when they were still in junior high school. Meinwald was also a music aficionado and studied flute withMarcel Moyse– the world's greatest flutist of his time.[according to whom?]

Career[edit]

Jerrold Meinwald was born in 1927 in New York City.[1]He studied chemistry at the University of Chicago where he earned his Bachelor of Science degree in 1948. He then went on toHarvard Universitywhere he obtained his Ph.D. withR.B. Woodwardin 1952. A DuPont Fellowship brought him to Cornell, where he has spent most of his subsequent career.

Series from a study by Meinwald and Eisner investigating defensive spray inChlaeniusbeetles with paper that turns dark in response to chemicals.

Since the early 1960s, he has worked, often in collaboration withThomas Eisner,on chemical signalling in animals, particularly insects and arthropods; he is regarded as one of the founders of the field of chemical ecology. A particular field of interest was the ways in which insects either use chemicals synthesised by the plants that they feed on, or use those plant chemicals as substrates from which to synthesize their own. A species on which he and Eisner published several times over decades is the mothUtetheisa ornatrix,whichcollects pyrrolizidine alkaloidsfrom its food source[2]and uses them as a deterrent to predators; the male also uses them as a pheromone[3]and passes them on in its semen to the female who uses them to make her eggs unpalatable.[2][4][5]

In analysing the constituents of plant signalling, he developed a number of retrosynthetic techniques, including theMeinwald Rearrangementwhere anepoxideis converted to acarbonylin the presence of aLewis acid;he has also performed substantial research over forty years in NMR spectroscopy.[6]and in reactions for producing chiral derivatives in order to determineabsolute configurationsof chiral molecules.[7][8]

In 1981, Meinwald became a founding member of theWorld Cultural Council.[9]He died in Ithaca on April 23, 2018, at the age of 91.[10][11]

Awards[edit]

He won theNational Medal of Sciencein 2012.[12][13][14]He was a member of theNational Academy of Sciencessince 1969, Fellow of theAmerican Academy of Arts and Sciencessince 1970, and member of theAmerican Philosophical Societysince 1987. Other notable honours:
