Florian Cosandey's painted Herbarium

In the 1970s, botany students could see a distinguished gentleman smoking a cigar at the end of the corridor, leaning over a drawing table of his own design. This was Professor Florian Cosandey who, after his retirement, continued to produce large-format botanical plates (98 x 73 cm) to illustrate his lectures. At the time, there were few other ways to present images in a lecture hall. These plates are drawn in coloured pencils, gouache and watercolour. The result is striking: thanks to this technique and Florian Cosandey's talent, the objects depicted take on a surprising relief, both from close up and from a distance. Professor Pierre Hainard took these 200 plates with him when he left the Institute and the Botanical Museum. He used them to illustrate his lectures. When he retired in 2002, these plates, now obsolete in the face of today's extraordinary and expensive computer technology, were recovered by the Cantonal Botanical Museum.
