"One of the book’s startling revelations about Curt Prüfer, a German diplomat in Cairo with espionage connections, is that he deployed Minna Weizmann — a seldom-mentioned sister of Chaim Weizmann, Israel’s first president — as a pro-German spy. Also involved in espionage was Aaron Aaronsohn, a Zionist and agronomist, who worked his way into the good graces of the Ottoman regime."
PS Apologies to readers. It was too early in the morning and I rushed. This was WWI.
