Knut Johann Ångström

Knut Johann Ångström ( January 12, 1857 - March 4, 1910 ) was a Swedish physicist.

Anders Jonas Ångström's son studied at Uppsala University from 1877 to 1884 . After his licentiate, he briefly went to the University of Strasbourg to study with August Kundt . Back in Uppsala, he obtained his doctorate and in 1885 became a lecturer in physics at the new university in Stockholm , where he planned and set up the physical institute. In 1890 he was elected a member of the Leopoldina Scholars' Academy . In 1891 he returned to Uppsala and in 1896 became professor of physics. One of his closest collaborators was Eva von Bahr , Sweden's first female physics professor.

He studied the radiant heat of the sun and absorption of the earth's atmosphere. In 1893 he invented his electrically compensated pyrheliometer .
