Alfred Wilhelm Volkmann (1801 – 1877) was a German physiologist, anatomist, and philosopher who was a Professor of Physiology at Halle. Today, he is most remembered for his additions to the physiology of the nervous system and physiological optics. In 1842 he demonstrated that sympathetic nerves were largely made up of medullated fibres arising from sympathetic and spinal ganglia. However, he also delineated and identified numerous features of gross anatomy, including Wolkmann's Channels.
