The brothers spent years collecting and researching folk tales. In 1812 they published Children’s and Household Tales, a collection which became known as "Grimm’s Fairy Tales". Wilhelm married in 1825, but Jacob never wed and for most of his life lived in his brother’s home.
Jacob Ludwig Carl Grimm, (1785-1863) and his brother, Wilhelm Carl Grimm, (1786-1859) were born in 19th century Germany to a large family. The family was poor but their generous aunt made it possible for them to attend the University of Marburg. Jacob studied medieval literature and the development of language. He and Wilhelm had intended to become lawyers but after one term at the University of Gottingen they both became entranced with folklore. They became known as "The Fathers of Modern Folklore Science". Their contributions to storytelling established folklore as a field for scholars. Their stories set the standard by which future folklore artists would be judged.
