JOHN D. ROCKEFELLER

John Davison Rockefeller

1839–1937 · American

role:Industrialist; founder of Standard Oil

nationality:American

connection:Rockefeller was among the prominent public figures who took up and endorsed Fletcher's mastication doctrine, advising slow and thorough chewing ('Fletcherize') in place of gobbling food. The association is recorded in histories of the fad, including the Christen medical-history review (1997), and was widely reported in the period. He appears here as an endorser whose public standing lent the doctrine visibility, not as a clinical subject; his own long life (he died in 1937 at ninety-seven) was popularly attached to such habits but is not evidence that mastication extends life.

confirmed:yes

NOTES

John D. Rockefeller (1839-1937) appears in this case as a prominent endorser of Fletcherism. The founder of Standard Oil publicly recommended slow, thorough chewing, and the verb “to Fletcherize” was attached to his counsel against gobbling food. The endorsement mattered to the doctrine the way Kant’s letter mattered to Hufeland’s macrobiotics: it lent the prestige of a famous name to a regimen that had no controlled-outcome evidence for its central health claims. Rockefeller’s exceptional longevity was sometimes cited in support of the habit, but a single long life is a testimonial, not a demonstration that the regimen prolongs life.
