Alexandre Hannesse signs his works as "Gothlieb Tjiackk". Born in Brussels in 1970, where he lives and works. Always tempted by photography in particular by portraits, Alexandre Hannesse worked in the nineties as an assistant photographer focused on black & white portraits. He'll follow this influence all his life as an artist. At the end of the nineties he'll take the liberty to participate in some small competition-exhibitions which ended in great trophies. In 2000 he decides to go to Portugal and work together with another artist in order to study once more the art of the portrait. He'll do this a year long. In 2006 supported by his sensibility and his keen eye on the world around him, Alexandre Hannesse decides to create "Gothlieb Tjiackk" an imaginary artist, issued out of a fusion between art and evil. He then developed "Nocif'Art", an artistic creation resulting from a sick community, its ideas and its products but also its immoderate overconsumption by people.
