Who is this lady?

[Eva Elisabeth]

I forgot: Victor Lemoine dedicated a peony to her which is said to be the worldwide most selling peony cultivar.
           
One last aside: Victor Lemoine (1823-1911) was a celebrated French flower breeder who also created many of today's lilac varieties. (As a result of his accomplishments, the term French lilac has come to mean all cultivars of the common lilac that have double flowers, regardless of their origin.)
