Frithiof Holmgren

Alarik Frithiof Holmgren, M.D.

Alarik Frithiof Holmgren (October 22, 1831 – August 14, 1897) was a Swedish physician, physiologist and professor at Upsala University, most noted for his research of color blindness. He was a vocal opponent of vivisection, and particularly the use of curare to immobilize subjects so they appeared peaceful while enduring great pain.[1]
