Lampshade not included
He was the son of Lars Hansen Hjort (b. 1794, d. 1880) and Maren Kirstine Knudsen (b. 1802, d. 1891) and brother of school inspector Andreas Larsen Hjorth. He lived in Østergade in Rønne. He began as an apprentice with Edvard Christian Sonne (b. 1810, d. 1876)

When he finished his education, he traveled to Germany (Schumann's porcelain factory in Berlin), Switzerland and northern France, among other places, to improve his skills by working at various ceramic factories.

On March 9, 1859, Hjort founded L. Hjorth's Terracotta Factory in a small workshop in Østergade where he lived, but later in 1862 moved to Krystalgade 5. Terracotta, stoneware and earthenware were manufactured here. The same year Hjort married Agnete Marie born Wolffsen, (b. 1840, d. 1908) who was a daughter of another earthenware manufacturer on Bornholm. Many of his productions are strongly inspired by the Danish sculptor Bertel Thorvaldsen.

Hort was not only a skilled artist, he also understood that if his factory was to survive the competition of other potters' companies, he would have to deal with marketing. In addition, Hjort participated in countless of the then both national and international industrial exhibitions and took home several prizes. He announced them in his catalogs: Nakskov 1868, Altona 1869, London 1870. It could well be that some of his works were sold abroad to enthusiastic Danes, who then later at the bottom could find a stamp from Hjort's factory in Rønne.

Many well-known artists joined Hjort's factory, such as Kristian Zahrtmann, who gave him several tips in the production of works of art, and Holger Drachmann, who, by earning extra money from Hjort, was able to maintain his artistic interest. But Drachmann was also a win for Lauritz Hjort. His artistic sense meant that Drachmann could come up with ideas for new motifs for vases and jars.
