Sébastien Tessier is a French comic artist, who works under the name Damour. Born in La Roche-sur-Yon in the Vendée department, he worked in painter Jacques Golly's atelier Ma Gomme before obtaining his degree in Plastic Arts in Bordeaux. His initial focus was to become an art teacher, but he eventually turned to creating comic art after meeting representatives of the publishing house Delcourt at the Angoulême comics festival of 1994.
