Jacob Ludwig Karl Grimm, also known as Ludwig Karl, was a German author, linguist, philologist, jurist, and folklorist. He formulated Grimm's law of linguistics, and was the co-author of the Deutsches Wörterbuch, the author of Deutsche Mythologie, and the editor of Grimms' Fairy Tales. He was the older brother of Wilhelm Grimm; together, they were the literary duo known as the Brothers Grimm.

During the research for his 'History of the German Language' Grimm corresponded with numerous colleagues. Ghent University Library holds several letters between Jacob Grimm and Jan Frans Willems.
The Deutsches Wörterbuch, abbreviated DWB, is the largest and most comprehensive dictionary of the German language in existence. Encompassing modern High German vocabulary in use since 1450, it also includes loanwords adopted from other languages into German. Entries cover the etymology, meanings, attested forms, synonyms, usage peculiarities, and regional differences of words found throughout the German speaking world. The dictionary's historical linguistics approach, illuminated by examples from primary source documents, makes it to German what the Oxford English Dictionary is to English. The first completed DWB lists over 330,000 headwords in 67,000 print columns spanning 32 volumes.
