Jean Ziegler is the most controversial and, after Roger Federer, arguably the most internationally recognized representative of Switzerland. For some, he is a solitary fighter against poverty and hunger in Africa and elsewhere in the world; for others, he is simply a scoundrel. The leftist sociology professor, bestselling author, and UN diplomat Ziegler shows no moderation in his accusations against the powerful of the world. His life is full of contradictions, which he has always overlooked until now, and which are examined in detail for the first time in this first authorized biography. This fluidly narrated, critical portrait depicts a man who, even at the age of 76, has not yet resigned himself.
