"Tetralogy of Fallot" and Etienne-Louis Arthur Fallot.

The eponym "tetralogy of Fallot" did not become a common noun in pediatric cardiology vocabulary for several decades after Etienne-Louis Arthur Fallot's report in a French medical journal. There were others before Fallot who described the abnormal cardiac anatomical findings seen in tetralogy of Fallot, but his name became fixed to the condition's eponym primarily through Maude Abbott popularizing the term.
