At the end of World War I and in light of Germany’s defeat, the economic situation of the “Ezra” company was dire. The Zionist Organization seized the opportunity and purchased the Technikum from it. Almost a decade later, the “Ezra” company was officially dissolved (in 1939). The purchase contract exists in two copies; the document was originally written in German, accompanied by a brief Hebrew translation. The content of the document is a sales agreement between Dr. James Simon and Dr. Paul Nathan representing the “Ezra” company, and Dr. Otto Warburg, President of the Zionist Organization, regarding the sale of the Technikum assets from the “Ezra” company (the seller) to the Zionist Organization (the buyer). The author of the document is lawyer Felix Mackover, and the addressees are Dr. Simon, Dr. Nathan, and Dr. Warburg.
