To Otto Juliusburger, in German. Einstein is delighted that Juliusburger has written an article about "Popper" [apparently the Austrian Jewish thinker Josef Popper-Lynkeus, in whom Juliusburger had an interest], to whom he refers as "the excellent man": "I feel that you have done Popper justice and have transmitted a vivid impression to a more distant observer". The article was evidently inscribed with a friendly reference to a visit from Einstein himself: "The added written remark on my visit touched me greatly, even if I know well that a friendly illusion lies behind it".
Popper-Lynkeus was a wide-ranging thinker in both the scientific and social spheres: one of his most notable ideas was the proposition of a new social system in which all individuals are provided with goods of primary necessity.
