In 2009, by pure chance, I met the beekeeping master Adolf Kieweg who showed me his beekeeping using sustainable, ecological and natural methods. In retrospect, I can see Adolf Kieweg not only as a professional teacher; he and his family also became good friends. Thanks to them I came to other contacts and friendships with people who had my same passion, for example with the master of beekeeping and farmer Hans Beer. Unfortunately Adolf Kieweg departed in 2013 too soon after a long and serious illness. Hans Beer continued to be close to me as a friend, colleague and advisor, and passed on his knowledge acquired in decades of beekeeping and agriculture. So his sudden death in December 2017 was a huge loss for me. These two of my friends beekeepers have influenced me a lot and have always supported me in what I was doing. To the Kieweg and Beer families my heartfelt thanks go out for the help and support they gave me in our years of friendship and collaboration.
