Bob de Moor

Robert Frans Marie De Moor (20 December 1925 – 26 August 1992), better known under his pen name Bob de Moor, was a Belgian comics creator. Chiefly noted as an artist, he is considered an early master of the Ligne claire style. He wrote and drew several comics series on his own, but also collaborated with Hergé on several volumes of ''The Adventures of Tintin''. He completed the unfinished story ''Professor Sató's Three Formulae, Volume 2: Mortimer vs. Mortimer'' of the ''Blake and Mortimer'' series, after the death of the author Edgar P. Jacobs.
