"I first met Burkhard 1993 at ITB in Berlin. He was running from booth to booth trying to extract bits and pieces of contact information from each exhibitor for the World Tourism Directory that he had created. Even at that time, he had already created what was then the world's most comprehensive directory of nearly every type of public and private sector organizations involved in tourism. At the time, I was in charge of building UNWTO's communications programs, including publications. I was impressed by Burkhard's dedication to the Directory and intense eye for details and so also was then Secretary-General Antonio Enriquez Savignac. We agreed to co-publish the Directory with KG Saur, a major German publisher and then distribute copies to all of UNWTO's members, as well as make it available for sale. The Directory went through various iterations after the SG and I moved on from the UNWTO, but Burkhard persisted and continues to persist today with a successful website that still provides one of the best directories of tourism organizations. By this point, Burkhard probably has the entire database memorized. He continues to be THE "go-to" authority for information on tourism-related organizations in every country and territory around the world."
