Amand Jamar was born in liege in 1870. It was after earning his doctorate in law at the University of Liege he realizes his dream by enrolling at the Royal Academy of Fine Arts in Liege where his teachers were Evariste Carpentier and Adrien De Witte. Jamar also creates watercolors and gouaches by methods of its own, disconcerting virtuosity and delicacy. They are somehow leaves "flying" a master artist who reacts to the heart of the clarity and movement.

But it was around 1930 that Jamar conquers the style that will preside over the creation of his most powerful. The painter seems so in complete fusion with nature and landscape subjects staged. Jamar lets himself increasingly caught up in the gesture of the hand holding the brush. But this increased confidence in the impulsivity of the act of painting which announced, to some extent, "action painting", is dominated by the need to organize forms the subject in recalling the objective reality. The fascination of space of the sky, rain or sea, the twist imparted to the objects represented in the tables give the time dimension "Baroque", Dionysian, translated into pictorial language of great flexibility.

Armand Jamar was named Chevalier of the Order of Leopold. Another honor: the issuing of a postage stamp, self-portrait in 1874
