Johann Hoffmann (28 March 1857 - 1 November 1919) was a German neurologist born in Hahnheim.
He is remembered for describing Hoffmann's reflex and Werdnig–Hoffmann disease (now spinal muscular atrophy type 1). He is also known for the adult-onset hypothyroid myopathy, Hoffmann syndrome.[1] He was educated at Worms and studied medicine at Heidelberg. He worked under Professor Wilhelm Erb, and succeeded him as head of neurology at Heidelberg.
Hoffmann died in Heidelberg.
