Archibald Douglas McAlpine (19 August 1890 – 4 February 1981) was a British neurologist who pioneered research into multiple sclerosis. His book "Multiple sclerosis", published first time in 1955, has since his death been published with the title "McAlpine's Multiple Sclerosis", and has become the standard reference for multiple sclerosis researchers. Dr McAlpine was the first one to suggest mercury poisoning as the probable cause for the Minamata disease.
