Emil Georg Cohn (28 September 1854 – 28 January 1944), was a German physicist.
Cohn was born in Neustrelitz, Mecklenburg on 28 September 1854. He was the son of August Cohn, a lawyer, and Charlotte Cohn. At the age of 17, Cohn began to study jurisprudence at the University of Leipzig. However, at the Ruprecht Karl University of Heidelberg and the University of Strasbourg he began to study physics. In Strasbourg, he graduated in 1879. From 1881 to 1884, he was an assistant of August Kundt at the physical institute. In 1884 he habilitated in theoretical physics and was admitted as a private lecturer. From 1884 to 1918, he was a faculty member of the University of Strasbourg and was nominated as an assistant professor on 27 September 1884. He dealt with experimental physics at first, and then turned completely to theoretical physics. In 1918 he was nominated as an extraordinary professor.
After the end of World War I and the occupation of Alsace-Lorraine by France, Cohn and his family were expelled from Strasbourg on the Christmas Eve of 1918. In April 1919, he was nominated as a professor at the . From June 1920, he gave lectures about theoretical physics at the University of Freiburg. In 1935 he retired in Heidelberg where he lived until 1939. He resigned from the Deutsche Physikalische Gesellschaft (DPG) together with other physicists like Richard Gans, Leo Graetz, George Jaffé, Walter Kaufmann, in protest at the despotism of the Nazi regime.
