Juha Antero Hernesniemi (18 October 1947 – 25 June 2023) was a Finnish neurosurgeon and academic, whose clinical work focused on the microsurgical treatment of intracranial aneurysms and arteriovenous malformations (AVMs). He served as chair of neurosurgery at Helsinki University Hospital (HUS) and as professor at the University of Helsinki from 1997 to 2015.
Hernesniemi was born in Kannus, Finland. He studied medicine at the University of Zurich, receiving his MD in 1973, and later earned the degree of Doctor of Medical Science at the University of Helsinki in 1979.[1][2] His dissertation was titled An analysis of outcome for head-injured patients with poor prognosis.[1][3] During his time in Zurich, he was influenced by Professor M. Gazi Yaşargil.[3]

After positions in Helsinki, Kuopio and Uppsala (1979–1983), Hernesniemi served as assistant chief physician (1983–1991) and chief physician (1991–1997) at the Department of Neurosurgery at Kuopio University Hospital; he spent 1992–1993 as a research and teaching fellow at the University of Miami. In 1997 he was appointed chair of neurosurgery at HUS (Töölö), serving until he retired from his post in 2015.[2] Contemporary Finnish sources reported that he performed approximately 400–500 operations annually at HUS.[4]
