Jacob Ludwig Carl Grimm (Hanau, January 4, 1785 – September 20, 1863 in Berlin), German philologist, jurist and mythologist, was born at Hanau, in Hesse-Kassel (or Hesse-Cassel). He is best known as the discoverer of Grimm's Law, the author of the monumental German Dictionary, his Deutsche Mythologie and more popularly, as one of the Brothers Grimm, as the editor of Grimm's Fairy Tales.
Jacob Grimm's father, who was a lawyer, died while he was a child, and his mother was left with very small means; but her sister, who was lady of the chamber to the Landgravine of Hesse, helped to support and educate her numerous family. Jacob, with his younger brother Wilhelm (born on February 24, 1786), was sent in 1798 to the public school at Kassel.
In 1802 he proceeded to the University of Marburg, where he studied law, a profession for which he had been destined by his father. His brother joined him at Marburg a year later, having just recovered from a long and severe illness, and likewise began the study of law.
