Erik Edlund (* Swedish Närke Province March 14, 1819 † Stockholm, August 19, 1888) was a Swedish physicist who investigated fluid motion, polarization of light during a total eclipse, and thermal phenomena accompanying changes in volume of solids. He studied electricity, describing a method of simultaneously transmitting messages in opposite directions along the same telegraph wire. He investigated the heat given off by induction currents. He studied electromotive forces generated when two different metals are put in contact. He investigated the resistance of arc lamps. He developed a theory of atmospheric electricity to explain the phenomenon of the northern lights.
He obtained his Ph.D. in physics in 1845 at Uppsala University under Svanberg. Edlund then worked under Weber in Leipzig for two years after obtaining his Ph.D.
Edlund is notable as the doctoral advisor of Svante Arrhenius.
Edlund was employed as a physicist by the Royal Swedish Academy of Sciences in 1850, and became a...
