Coming from a relatively wealthy family, very close to artistic circles, Zeller spent his childhood in Melun and his early studies in Jacques Amyot college.
Seeking political benchmarks, Zeller was persuaded by Jean van Heijenoort to respond to the invitation by Trotsky to join him in Norway, where he was under house arrest.
[citation needed] Opposed to the Munich agreement and Nazism, Zeller became part of the French Resistance from the start of the German occupation of France.
[1] After the war, Zeller joined the Internationalist Communist Party, from September 1946 to the end of 1947, before participating in the creation of the Revolutionary Democratic Rally.
In 1948, he retired to Èze, a small village in the French alps, and two years later he created a museum of local history.
