Professor Carl Christian Tscherning, former General Secretary of the International Association of 

Geodesy and editor of Bulletin Geodesique, and a charismatic, outspoken, and grand master of 

geodesy, died unexpectedly on October 24, 2014, from complications following operations for 

intestinal problems. During Christian’s nearly 45 years of work with and for geodesy, including 

many years working actively for the International Association of Geodesy, Christian marked 

himself as a top level scientist especially in physical geodesy (“Mr. Collocation”), developing novel 

and advanced methods, always with a strong view on applications and practical software 

implementations, and being an inspirator, teacher and mentor for a long list of new generation 

students in geodesy and geophysics over the years.
