Gregor Mendel - detail of a painting by Phibus MatileThe picture is a detail from Gregor Mendel counting green and yellow peas in the Augustinian Abbey at Brno. It was painted in the early renaissance style by my friend and long-time colleague Phibus Matile. You will see his name as a co-author on many of the publications listed below. Phibus died in his 80th year on 29 October 2011. He was a brilliant, cultured, amusing, talented, unique man and will be greatly missed.
