My friends Primoz Pirih and Gregor Belušič sent me an article about Dr Dora Ilse.
Please read it via this link.
Dr Dora Ilse demonstrates that butterflies have a sense of colour, and that most of them discover flowers on their first approach through their colour and scent. She published her doctoral thesis in 1928.
I am amazed by her passion and detailed experiments, which we still use today, as well as her artistic talent; see her drawings in figures!
It is a true shame that her works are underappreciated.
I wish I could know her career in the '60s and '70s, which has disappeared.
