His first commission was to illustrate the Annales générales des Sciences physiques, printed by Weissenbruch under the scientific editorship of Jean Baptiste Bory de Saint-Vincent, Auguste Drapiez and Jean-Baptiste Van Mons.

The Société d’encouragement pour l’industrie nationale in Paris launched an international competition for lithographers in 1828, aimed at rewarding those who had made the greatest progress in their art.

In 1841 Jobard proposed in his newspaper adding what he called "extra emotional typographic characters" (including an irony punctuation) which may be considered precursors to present-day emoticons and emojis.

[1] In 1839 Jobard was appointed Commissioner for the Belgian Government at the French industrial exhibition in Paris, where he met François Arago, Louis Daguerre, baron Pierre-Armand Séguier amongst many other intellectuals and industrialists.

Jobard was appointed Director of the Musée Royal de l’Industrie in Brussels in 1841, where he developed his ideas of museology which already then met modern-day requirements for conservation, cataloguing, study and popularization.

Jobard developed an economic and social theory that he called "Monautopole" and that he defined as "from monos, alone, autos, oneself and pôleô, dealing".
