Fred Warren McLafferty (May 11, 1923 − December 26, 2021) was an American chemist known for his work in mass spectrometry. He is best known for the McLafferty rearrangement reaction that was observed with mass spectrometry.{{cite journal | author = F. W. McLafferty| title = Mass Spectrometric Analysis.

Early life and education

Fred McLafferty was born in Evanston, Illinois in 1923, but attended grade school in Omaha, Nebraska, graduating from Omaha North High School in 1940.{{cite journal |author=Gross ML |title=Focus in honor of Fred McLafferty, 2003 Distinguished Contribution awardee, for the discovery of the "McLafferty Rearrangement" |journal=J. Am. Soc. Mass Spectrom. |volume=15 |issue=7 |pages=951–5 |year=2004 |pmid=15234352 |doi=10.1016/j.jasms.2004.05.009|doi-access=free |bibcode=2004JASMS..15..951G }} The urgent requirements of World War II accelerated his undergraduate studies at the University of Nebraska; he obtained his B.S. degree in 1943 and thereafter entered the US armed forces. He served in western Europe during the invasion of Germany and was awarded the Combat Infantryman Badge, a Purple Heart, five Bronze Star Medals and a Presidential Unit Citation.{{cite book|first=Michael A. |last=Grayson|title=Fred W. McLafferty, Transcript of Interviews Conducted by Michael A. Grayson at Cornell University Ithaca, New York on 22 and 23 January 2007 |date=23 January 2007 |url=https://oh.sciencehistory.org/sites/default/files/mclafferty_fw_0352_full.pdf|place=Philadelphia, PA|publisher=Chemical Heritage Foundation }}

He returned to the University of Nebraska in late 1945 and completed his M.S. degree in 1947. He went on to work under William Miller at Cornell University where he earned his Ph.D. in 1950. He went on to a postdoctoral researcher position at the University of Iowa with R.L. Shriner.

Dow Chemical

He took a position at Dow Chemical in Midland, Michigan in 1950 and was in charge of mass spectrometry and gas chromatography from 1950 to 1956. In 1953–1956, he started collecting reference mass spectra whenever the instruments were not in use.{{Cite journal |last=McLafferty |first=Fred W. |date=2011-07-19 |title=A Century of Progress in Molecular Mass Spectrometry |url=https://www.annualreviews.org/doi/10.1146/annurev-anchem-061010-114018 |journal=Annual Review of Analytical Chemistry |language=en |volume=4 |issue=1 |pages=1–22 |doi=10.1146/annurev-anchem-061010-114018 |pmid=21351881 |bibcode=2011ARAC....4....1M |issn=1936-1327|url-access=subscription }}

In 1956, he became the Director of Dow's Eastern Research Lab in Framingham, Massachusetts. During this time, he developed the first GC-MS instruments and analyzed the company's reference collection of spectra he himself founded. This allowed him to work out techniques for determining the structure of organic molecules by mass spectrometry, most notably in the discovery of what is now known as the McLafferty rearrangement.{{cite journal|last=McLafferty|first=F.W.|title=Mass Spectrometric Analysis.

Academic career

From 1964 to 1968, he was Professor of Chemistry at Purdue University.{{Cite web|title=Fred W.

W. Debye Professor of Chemistry. He was elected to the United States National Academy of Sciences in 1982.{{Cite web|title=Fred W.
