Magnus Gustaf Blix (25 December 1849 – 14 February 1904) was a Swedishphysiologist born in the parish Säbrå, presently located inHärnösand Municipality. He is the grandfather of UN weapons inspectorHans Blix.
During his career he was a professor at the Universities ofUppsala andLund. Blix was elected a member of theRoyal Swedish Academy of Sciences in 1892.
Blix is best known for his work in the 1880s involvingsomatic sensation. He discovered that electrical stimulation on different points on the surface of the skin caused distinct warm or cool sensations. Subsequently he built a "temperature stimulator" which showed that a decreased skin temperature produced cool sensations from localized spots at separate skin locations. He also discovered that increased temperature induced warm sensations from differentcutaneous locations. In addition he performed tests that involved localizedtactile sensitivity.
In 1881–82 Blix published his findings in two important documents. During this time frame, GermanneurologistAlfred Goldscheider (1858–1935), and American physician Henry Herbert Donaldson (1857–1938) ofJohns Hopkins University were performing similar experiments, independent of Blix.
Blix is also credited for conducting extensive research on thephysiology ofmuscles.
He died inLund.
