I freely admit my ignorance of Antoine Marie Jean-Baptiste Roger, comte de Saint-Exupéry. You can't know about everyone, nor should you be expected to. I gather, after a quick look see on Google, he was of some import. Still I don't see why the uiniversity took so much against him that it removed a rather large version of the above inscription from the courtyard behind the library and replaced it with this piddling thing that seems to be covering up some utility port in a flower bed that you would quite easily miss. Below is how the old feature looked taken from the 2008 University report it's been replaced by a giant comma. Clearly pauvre Antoine is no longer flavour of the month.
