Edmé Félix Alfred Vulpian (5 January 1826 – 18 May 1887) was a French physician and neurologist. He was the co-discoverer of Vulpian-Bernhardt spinal muscular atrophy and the Vulpian-Heidenhain-Sherrington phenomenon.
Vulpian was born in Paris, France, in 1826. Among other noted discoveries and experiments, Vulpian discovered adrenaline in the adrenal medulla. He was the first to use the term "fibrillation" to describe a chaotic irregular rhythm of the heart.
