Groth, Klaus Johann (Heide, Holstein, 1819-99, Kiel), a countryman by birth and upbringing, from the district of Dithmarschen, became in his teens factotum to the parish clerk, and was then trained at Tondern as a teacher. From 1841 to 1847 he taught in a girls' school in Heide; he spent his leisure hours in the study of the dialect of the region, working so hard that in 1847 he had a breakdown. From then until 1853 he lived at the home of a friend on the Baltic island of Fehmarn, writing his best-known work, the collection of poems in Low German dialect (Holsteiner Platt), which was published in 1852 as Quickborn. From 1853 to 1855 he worked at Kiel with K. Müllenhoff (1818-84) on the orthography of Holstein dialect, and in the following years visited Bonn, Leipzig, Dresden, and Weimar. He married in 1858 and became a professor at Kiel University in 1866. He visited England in 1872-3.
Groth's other publications did not equal Quickborn (which was expanded in 1853, 1854, and especially in 1871) either in popularity or importance. They include Hundert Blätter (1854, in High German), Vertelln (2 vols. of stories, 1855-9), the verse idyll Rotgetermeister Lamp un sin Dochder (1862), and a further set of stories (Ut min Jungsparadies, 1876). He also published treatises on dialect (Briefe über Hochdeutsch und Plattdeutsch, 1858; Über Mundarten und mundartige Dichtung, 1876). He was awarded the Schiller prize in 1890. Groth's importance lies in his combination of dialect poet, scholar, and propagandist. The seriousness with which he approached the matter is reflected in his rejection of Reuter's Läuschen un Rimels as frivolous. His poetry is simple in structure, warm in tone, and inclined to sentimentality.
Gesammelte Werke appeared in 1893 (4 vols.) and Sämtliche Werke, 1952-65 (8 vols.).
