Introduction: Special Issue on Vitamin D Dedicated to the Memory of Anthony W Norman

Abstract

Tony Norman was acutely aware of the importance of sharing scientific data with the whole world to promote the exchange of new information and ideas and to stimulate international collaboration. [...]he initiated a first small “workshop on vitamin D" in 1973 in Frankfurt (Germany), rapidly followed by a much larger meeting in Wiesbaden (Germany) in 1974. [...]the vitamin D workshops were organized every 3 years, alternatively in North America and Europe. Because of the rapid expansion of vitamin D research, annual workshops were organized from 2012 onwards. Tony Norman inspired the vitamin D community for nearly 50 years by the organization of the workshops and the publication of the proceedings of each meeting. [...]the vitamin D community owes it to him to commemorate this important aspect of his scientific career.
