Jesse Francis McClendon (December 21, 1880 – November 22, 1976) was an American chemist, zoologist and physiologist. He is remembered today mainly for the first pH measurement of human stomach ''in situ''. Jesse F. McClendon made substantial contributions in a variety of fields, including invertebrate zoology, nutrition, life processes of cell membranes, the importance of pH control,〔''McClendon J. F.''

McClendon tested the healthfulness of hamburgers by putting a University of Minnesota medical student on only hamburgers and water diet for 13 weeks.〔(An unusual hamburger experiment is part of the University of Minnesota's dietary research annals.

First time he married in 1911 and had two children in this marriage. Second time McClendon married in 1936. He died on November 22, 1976 in Harleysville, Pennsylvania.

''Bulletin American Museum of Natural History. Vol. XXII, 1906, p. 119.〕 Then he received a Ph.D. in zoology from the University of Pennsylvania in 1906. 1907–1910: McClendon taught biology at Randolph-Macon College, then zoology at the University of Missouri. 1910–1914: McClendon was Assistant, Instructor in histology and embryology of the Weill Cornell Medical College of Cornell University.〔(Cornell University Information Database. )〕 He investigated frog blastomeres.〔 ''Pynes Ch.

In the Laboratory McClendon realized some pioneer researches: Low iodine-goiter relationship;〔''McClendon J. F.'' The distribution of iodine with special reference to goiter.
