In 2012 Joe Castello read in a news magazine that the global population of Jews was only about 13 million, and thereby was inspired to make the study you will find in these pages. He was already fascinated by Jewish culture and the land of Israel, following his visit in 1993. He was amazed to find that such a small population and its ancestors have had an irreplaceable impact on the world by virtue of their determination, tenacity and way of life. The book celebrates the number, for example, of Jewish Nobel prize winners, those in academia, the arts, commerce and show business to name but a few. Many household names are mentioned, all feted in their own field. Joe Castello is a Gentile, and hopes that others like himself will, through his work, gain a little insight into a fascinating heritage.
