went directly there, where his ardor and his free and easy behavior drew
upon him the admonitions of the proprietor. But nothing stopped him, and
he continued to touch everything, furnishing explanations to his
companions. When he returned to the college his pockets bulged with
prospectuses, catalogues, and selected brochures, which he carefully
added to the heterogeneous contents of his desk."[11]

Jean Krebs crystallized Georges Guynemer's vocation. He developed and
specialized his taste for mechanics, separating it from vague
abstractions and guiding it towards material realities and the wider
experiences these procure. He deserves to be mentioned in any biography
of Guynemer, and before passing on, it is proper that his premature loss
should be cited and deplored. Highly esteemed as an aviator during the
war, he made the best use of his substantial and reliable faculties in
the work of observation. Airplane chasing did not attract him, but he
knew how to use his eyes. He was killed in a landing accident at a time
almost coincident with the disappearance of Guynemer. One of his
escadrille mates described him thus: "With remarkable intelligence, and
a perfectly even disposition, his chiefs valued him for his sang-froid,
his quick eye, his exact knowledge of the services he was able to
perform. Every time a mission was intrusted to him, everybody was sure
that he would accomplish it, no matter what conditions he had to meet.
He often had to face enemy airplanes better armed than his own, and in
the course of a flight had been wounded in the thigh by an exploding
shell. Nevertheless he had continued to fly, only returning considerably
later when his task was done. His death has left a great void in this
escadrille. Men like him are difficult to replace...."
