Jacob Grimm

Jacob Ludwig Carl Grimm also known as Ludwig Karl, was a German philologist, jurist, and mythologist. He is known as the discoverer of Grimm's law (linguistics), the co-author with his brother Wilhelm of the monumental Deutsches Wörterbuch, the author of Deutsche Mythologie and, more popularly, as the elder of the Brothers Grimmand the editor of Grimm's Fairy Tales.

Grimm joined other academics (known as the Göttingen Seven) who signed a protest against the King of Hanover's abrogation of the constitution which had been established some years before. As a result, he was dismissed from his professorship and banished from the Kingdom of Hanover in 1837.

He returned to Kassel with his brother, who had also signed the protest. Grimm died on 20 September 1863 (aged 78) in Berlin, Kingdom of Prussia in the German Confederation at the age of 78, working until the very end of his life
