Arthur Van (or van) Gehuchten (20 April 1861 – 9 December 1914) was a Belgian anatomist, born in Antwerp. He was professor in the faculty of medicine at the University of Leuven until the start of World War I in 1914. He moved to England and taught biology at Cambridge University until his death. Van Gehuchten is especially known for his contributions to the theory of neurons. In anatomy, the van Gehuchten method is the fixing of a histologic tissue in a mixture of glacial acetic acid 10 parts, chloroform 30 parts, and alcohol 60 parts.
