Hadj Mohamed Dahou, was part of the Editorial board and then later Editor-in Chief of Potlatch, the "information bulletin of the French Section of the Lettrist International" from its first issue in 1953. He also went on to form the Situationist International with other Lettrists.

Unlike fellow Situationist Guy Debord, who dedicated the 1957 text "One More Try if You Want to be Situationists" to Dahou, there is not much published about Dahou himself, although it is thought that he enjoyed to smoke hashish and play the guitar.

He resigned from the SI in 1959.
