[2] Julien Schwarzer was born in the Marseille suburb of Saint-Barnabé in the 12th arrondissement of the city to a nurse mother and a truck driver father.

His paternal grandfather was a native of Berlin, Germany, who migrated to France and ultimately started a family there, hence his typically German-sounding surname.

He posted his material on the Skyblog site using the pseudonym Schneider, and in 2014 chose his stage name SCH.

In the early morning of August 26th, 2024, on a road in the Grand Travers district of Mauguio-Carnon, following a showcase by SCH in a nearby La Grande-Motte nightclub, a car transporting several members of the rapper's entourage was hit by automatic gunfire from another vehicle transporting four people.

[23] SCH was likely targeted, but changed cars at the end of his performance, which may have saved his life.
