Ninety and still active in research

Abstract

His efforts in comparative anatomy and morphology are commended. An open mind throughout his life with sharp scientific reasoning opened him a world of solid arguments based on evidence to prove his view, sometimes after decades. Exemplary are the discussions about the adenoma-carcinoma sequence or his views on anatomical structures limiting the spread of cancer cells. We note his continuing research activities well beyond normal pension age. At the age of over 90, he is still a very sought-after conference speaker.
