Jérôme Lulling is a linguist from Luxembourg who has been a leading figure in preservation and educational efforts relating to the Luxembourgish language, a Germanic language that became one of Luxembourg’s three official languages in 1984 and spoken by 300,000 persons.
Lulling’s initial contributions to enhancing the language took place between 2000 and 2002, when he compiled the language’s first computer spellchecker as part of his Ph.D. dissertation at the Université Paul Valéry de Montpellier. The spellchecker, which consisted of 125,000 words, was known as Projet C.ORT.IN.A.
Lulling, working in partnership with fellow linguists François Schanen and Manfred Peters, compiled and edited the first Luxembourgish-French dictionary, Dictionnaire Bilingue Français-Luxembourgeois, which was published in 2005. The text consisted of 48,000 translated words and phrases. Lulling is also the co-author of Luxdico, the Luxembourgish online dictionary. 
In 2011 Lulling published a DVD to learn Luxembourgish called 'LuxDVD - learning luxembourgish with videos'
