Hans Ariëns Kappers

Johannes (Hans) Ariëns Kappers was a Dutch director of the Netherlands Institute for Brain Research , Professor of Neuroanatomy at the University of Groningen and University of Amsterdam , member of the Royal Netherlands Academy of Sciences and Knight in The Order of the Dutch Lion .

Ariëns Kappers finished in 1929 at the Amsterdam Lyceum . After his graduate of medicine at the University of Amsterdam, he became a student assistant at the Anatomical-Embryological Laboratory in 1932 at MW Woerdeman, who was then only professor Dr. L. Bolk succeeded. He was promoted after his semi-art examinations and published during that period the relationship between brain and body weight during development. In 1937 Ariëns Kappers was appointed as a principal assistant at the Anatomical-Embryological Laboratory in Groningen . In 1938 he graduated at the University of Amsterdam with Professor Woerdeman on Biometric Contribution to the knowledge of the ontogenetic development of the human pelvis .

Ariëns Kappers worked again from 1942-1945 as an assistant at the Anatomical Laboratory in Amsterdam, in the same building where his uncle CU Ariëns Hairdresser , since 1909, was the first director of the Center for Brain Research, housed with his staff. Ariëns Kappers described during that period, among other things, a case of microcephaly , published about reptile hyperlipids and continued his allometric studies on brain and body weight in a variety of species. He returned to Groningen in May 1945, where he was appointed professor of anatomy and embryology in 1946 and was appointed as a rector magnificate in the years 1956-1957. During this period, its comparative neuroendocrine emerged, which resulted in various publications, such as the paraphysis cerebri in lower vertebrates and humans, the neuro pituitary gland of the exolotl, the connections between the hypothalamus and the pituitary gland and the functions of the plexus chorioides . The new insight regarding the possible damage to the intrauterine brain development by a virus was published in three languages ​​in the years 1955-1956 on the basis of a case of brain defects in a 6-week human embryo embryo pathology rubeolosa . His first article about the epiphysis of the rat appeared in 1960.

In 1962 Ariëns Kappers was appointed Director of the Center for Brain Research and Extraordinary Professor of Anatomy and Embryology at the University of Amsterdam. His inaugural speech was about The eye of Siva, the pineal gland or epifyse. In 1963 he organized the first international congress on this subject entitled The structure and function of the epifysis cerebri . The congressional contributions were published as a thick volume in the Progress in Brain Research series. In addition to his comparative morphological studies, Ariëns Kappers investigated the histochemical structure and endocrine functions of the epiphyseal. Under his leadership, the Brain Institute grew into a multidisciplinary research center and the cradle of many professors at universities worldwide.

Ariëns Kappers was co-founder of TELEAC and NOS crown member, board member of the Royal Institute for Education of the Blind, chairman of the department of Amsterdam, from the Society to the Utility of the General , and Vice Chairman of the Henri Frankfort Board of the Foundation for Mediterranean Pre - a proto history. He was also a member of the Royal Netherlands Academy of Sciences and Sculptor .
