Ronald Gruner, who spent his working career as a CEO of three different tech companies (Alliant Computer; Shareholder.com; and Sky.Analytics), is a lay historian deeply interested in economic policy and outcomes. His book, analyzing the presidencies of the 17 U.S. Presidents from Warren G. Harding to Donald J. Trump, focuses largely on issues like unemployment, interest rates, and inflation. But along the way he also makes mention of significant geopolitical events that occurred during those presidencies. I will leave it to economists to determine the value of Gruner’s economic analyses. They are beyond my depth. What I did take notice of was how often our fellow Jews, and issues of direct relevance to the Jewish community, cropped up in the book. [Donald H. Harrison]
