Due to: Anny Jacob / Hedi Grimm / Werner Grimm / Bruno Müller: Alte Rosen und Wildrosen, Stuttgart (1990), S. 26-27, is the name of the breeder of Conrad Ferdinand Meyer and so on "Dr. Hermann Müller" not "Dr. Fr. Müller". Dr. Hermann Müller was born 1828 in Zweibrücken, Germany, and began breeding roses in Weingarten, Germany round about 1882. Especcially breedings with r. rugosa and with Persian Yellow are notable.
