One year after Jakob Ludwig Karl Grimm started studying law at the University of Marburg, his younger brother, German author Wilhelm Karl Grimm, followed.
In 1825, Wilhelm married Henriette Dorothea Wild, also known as Dortchen. Together they parented four children: Jakob Grimm (1826-1826), Herman Friedrich Grimm (1828-1901), Rudolf Georg Grimm (1830-1889), and Auguste Luise Pauline Marie (1832-1919).
From 1837 to 1841, the Grimm brothers joined five of their colleague professors at the University of Göttingen to form a group, known as the Göttinger sieben. They protested against Ernst August, king of Hanover, whom they accused of violating the constitution. The king fired all seven professors.
Wilhelm Grimm died in Berlin.
