Born in 1923, Riboud became a photographer after World War II and became an in-demand photojournalist, who captured the brutality of war in Asia and Africa.

His most famous pictures included a workman painting the Eiffel Tower and another of a young woman presenting a flower to a bayonet-wielding soldier during an anti-Vietnam War demonstration at the Pentagon in Washington, D.C.

He also famously captured designer Yves Saint Laurent in his office in 1964.

One of the shots from the session was published in fashion historian Jeromine Savignon's 2014 book Yves Saint Laurent's Studio - Mirror and Secrets.
