Everything discussed within the Koninklijke Industrieele Groote Club remains secret, so Koen Kleijn (63) sometimes had to rely on other sources while writing his book
Author Koen Kleijn recounts the history of the Koninklijke Industrieele Groote Club in his latest book, Op stand aan de Dam. Because the club upholds a strict policy of secrecy, Kleijn was forced to rely on documents like statutes and membership lists rather than internal discussions to complete his research.
