History

The blue-green A-shape is reminiscent of the old emblem of Université Bordeaux 1 (that became Université de Bordeaux in 2013)

The design is derived from the older logo, drawn by Gerhard Niklasch (used from 1997 to 2012):

Gerhard described his work as follows in 1997:

As to the decorated letter `A', it was (mainly) derived from (a small version of) the emblem of the Université Bordeaux 1:

I simplified the colours (the emblem seems to have been derived either from scanned hardcopy, or from a much larger version; at any rate the green and blue bits are heavily dithered with a random pattern of darker and lighter pixels), dropped the outer fields at top left and right, and dimmed the two middle arcs to bring out the `A' shape more clearly. The crossbar was added in a way that suggests some mathematics even to the layperson's eye. Also, if you're gifted with a lot of visual imagination, the resulting shape may remind you faintly of something in Paris.
