"Too famous for his work to be judged without bias, Gary felt he needed to break free from categorization. So, in 1973, at age 59 — the same age his mother was when she died — Gary invented Émile Ajar. He was by then twice divorced, retired from the diplomatic corps, and had published 22 books, including the Goncourt-winning The Roots of Heaven (1956), about illegal elephant poaching in Africa. It was time for a new adventure, as he explains in The Life and Death of Émile Ajar: “I was tired of being nothing but myself…there was the nostalgia for one’s youth, for one’s debut, for one’s renewal…. I was profoundly affected by the oldest protean temptation of man: that of multiplicity.” … events turned downright farcical. The Life Before Us was awarded the 1975 Prix Goncourt, the rules of which stipulate that it may be awarded to an author just once in his lifetime, and Gary had already received it for The Roots of Heaven. He instructed Ajar’s lawyer to turn down the honor on her client’s behalf, but the prize administrators would hear nothing of it. “The Goncourt Prize cannot be accepted or refused any more than life and death. Mr. Ajar remains the laureate.”"
