Friedrich August Benjamin Puchelt (27 April 1784, Bornsdorf near Luckau – 2 June 1845, Heidelberg) was a German pathologist remembered for coining the term "perityphlitis" to describe inflammation of the right iliac fossa in 1832.

[1] From 1804 to 1808, he studied medicine at the University of Leipzig, where from 1815, he served as an associate professor of pathology and therapy.

In 1820 he attained a full professorship, relocating to Heidelberg in 1824 as a professor of pathology and as director of its polyclinic.

During the same year, he was appointed court councillor to the Grand Duchy of Baden.

[2] He provided continued editorship of Johann Samuel Ersch's "Literatur der Medicin seit der Mitte des achtzehnten Jahrhunderts bis auf die neueste Zeit" (Literature of medicine since the middle of the eighteenth century up to recent times).
