Robert Frans Marie De Moor, 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.

The Adventures of Blake & Mortimer is a Belgian comics series created by writer and comics artist Edgar P. Jacobs. It was one of the first book series to appear in the Franco-Belgian comics magazine Tintin in 1946, and was subsequently published in book form by Belgian comic book publisher Le Lombard.
