The opening as it read in 2015
Dan Chamizer (born 1947) is an Israeli writer, artist, pilot, and radio quiz master. He is best known as the creator of the "Chamizer riddle". The riddle had started off on the Israeli daily radio talk show of Razi Barkai and Shelly Yachimovich – "Hakol Diburim" on " Reshet Bet ", in which Chamizer had a daily segment. It is based on an original coding system, and is now widely used to teach problem-solving in schools, government agencies and high-tech companies.1
