In den Warenkorb4to. 1 p. Blind embossed letterhead. To the lawyer, Zionist leader, and satirical writer Sammy Gronemann (18751952). A charming poetic letter of thanks, composed entirely in verse on the occasion of Einstein's 70th birthday.Rather than sending a conventional note of thanks, Einstein responds to Gronemann's birthday greetings wit…h an original poem celebrating his friend's wit and literary gifts. In three rhyming stanzas, he praises Gronemann's ability to meet the shortcomings of human nature with humour rather than condemnation:"Worum andre sich oft grämen / Weisst du mit Humor zu nehmen / Denn du hast dir halt gedacht / Dass uns Gott so hat gemacht."Einstein contrasts divine judgment with Gronemann's humane satire, concluding that, instead of judging with "stubborn severity," his correspondent brings "redemption through your poetry" ("Bringst Erlösung durch dein Dichten"), allowing both "the sinners and the pious" to recognize themselves. He closes with his heartfelt thanks and warm regards.Written shortly after Einstein's 70th birthday in March 1949, the letter is both a personal expression of gratitude and a remarkable literary tribute to one of the leading figures of German-Jewish culture. Sammy Gronemann, a lawyer, Zionist leader, playwright, and master of satirical comedy, had fled Nazi Germany and settled in Tel Aviv, where he became a central figure in the emerging Hebrew theatre. Einstein's choice to respond in verse, rather than prose, reflects both the warmth of their friendship and his admiration for Gronemann's lifelong belief that humour could temper fanaticism and illuminate human frailty.A delightful and highly unusual Einstein letter, uniting science and literature in an original poetic composition and revealing the physicist's rarely encountered playful literary side.

To the young aspiring Romanian physicist Melanie Serbu (1909-1979), in German living now in Zurich, Switzerland."I believe that the concerns of colleague Wenzel are entirely justified. What I wrote to you was just an insight, casually expressed without knowledge of the relevant specialized li…terature. Of course, I also don't have the time to engage with this literature and can, therefore, take no responsibility for the matter. However, it would probably be best to choose the topic of the dissertation in line with a colleague there. This way, you can be sure that the work will be accepted if it is completed to his satisfaction, whereas otherwise, you might risk expending a lot of effort in vain."Ich glaube, dass die Bedenken des Kollegen Wenzel durchaus berechtigt sind. Was ich Ihnen schrieb, war nur ein apercu, leichthin ohne Kenntnisse der einschlägigen Spezal-Literatur geäussert. Ich habe natürlich auch nicht Zeit, mich mit dieser Literatur zu befassen und kann deshalb in der Sache keinerlei Verantwortung übernehmen. Es dürfte aber wohl das Beste sein, das Thema der Dissertation in Einklang mit einem dortigen Kollegen zu wählen. Dann sind Sie sicher, dass die Arbeit angenommen wird, wenn sie zu dessen Befriedigung vollendet wird, während Sie sonst riskieren würden, eine Fülle von Arbeit nutzlos aufzuwenden.

In den Warenkorb4to. 1 page. To the German-American mathematician Ernst Gabor Straus. Einstein refers to a work he has just written in which he resolves the equations of the gravitational field issues from Bianchi's identities; he also congratulates Straus on a beautiful mathematical discovery and invokes by comparison the proof of transcendenc…e of numbers that the latter had simplified. - An assistant to Einstein from 1944 to 1948, Ernst Gabor Straus detected a computational error in one of Einstein's works and, in order to correct it, wrote a paper with him in 1946 entitled "A Generalization of the Relativistic Theory of Gravitation". In 1949, having left his position with Einstein at Princeton University, he published "Some Results in Einstein's Unified Field Theory". The two scientists remained in a working relationship afterwards. - On headed paper; perfectly preserved.

In den Warenkorb4to. 1 p. Signature and one handwritten correction in green ink. In German. Framed, matted and glazed (46 x 62 cm) with a photographic portrait. To the Russian-French hydrodynamic engineer Wsevolode Grünberg in New York City, concerning a contested inheritance matter in which Einstein had reluctantly agreed to assist. From 1939,… Einstein acted as a go-between for Grünberg and his friend János Plesch, an important Hungarian physician who had emigrated to England. "Concerning the inheritance matter", Einstein writes, "I regret having to report that we were not successful in getting my friend to England, as the War prevented it. Nor can I imagine that any hindrance remains to proceeding with the final settlement. I intend once more to encourage Mr. Plesch to put everything in order. As regards your inventions, I suggest that you send them for evaluation to my friend Professor Karman at the California Institute of Technology, who is a first-class expert and has influential connections to the realm of construction and practical implementation in the field. I enclose a letter to him [.]" (transl.). - Wsevolode Grünberg was the nephew of the Russian orthodontist and collector Josef Grünberg, a close friend of both Albert Einstein, who gave him the nickname "Bolshie", and János Plesch during their time in Berlin. It appears that Einstein and his second wife Elsa had become acquainted with Wsevolode Grünberg shortly before their friend's death in 1932. Travelling to America in 1939, Grünberg approached Einstein for an introduction to fellow engineers in the U.S. and help with his inheritance issue back in Europe. The two men met in June 1939 at the home of Irving Lehman in Port Chester, New York, and Einstein subsequently did what he could for Grünberg. In the early 1940s, Grünberg's important hydrofoil designs were used by the National Advisory Committee for Aeronautics (NACA) to build a seaplane model that was successfully tested at Langley, VA. Ironically, the classification of the project prevented the French citizen Grünberg from seeing the results of the tests until years after the war. Grünberg later became a U.S. citizen, changing his name to Waldemar A. Craig. - Traces of folds. On Einstein's embossed Princeton stationery.

In den Warenkorb4to. One page, 279 x 216mm. Blind embossed letterhead. In German. 'The controversy about the foundations of the physics of probability'. Einstein is sending in a separate packet the volume printed for his 70th birthday (Albert Einstein: Philosopher-Scientist). 'I am sending it to you as I think that the controversy about the fou…ndations of the physics of probability will perhaps interest you'. Once Bergmann has finished with the book, Einstein asks him to pass it to Rosa Dukas, sister of Einstein's assistant, Helen. Einstein has been discussing the problems of the Hebrew University with the recently-elected president, Selig Brodetzky, who has visited. Selig Brodetzky (1888-1954) was second president of the Hebrew University during a turbulent period, marked by the forced abandonment of the campus on Mount Scopus and disputes with the University Senate.

In den Warenkorb4to. 1 page. Einstein on the value of relativity for philosophy. Einstein writes to Hans Reichenbach, the philosopher of science and an influential expositor of Relativity. In part (translation): "I am really very pleased that you want to dedicate your excellent brochure to me, but even more so that you give me such high marks a…s a lecturer and thinker. The value of the th.[eory] of rel.[ativity] for philosophy seems to me to be that it exposed the dubiousness of certain concepts that even in philosophy were recognized as small change. Concepts are simply empty when they stop being firmly linked to experiences. They resemble upstarts who are ashamed of their origins and want to disown them." The letter was published in the Collected Papers of Albert Einstein, vol 10, doc 66, pp 323-324 (CPAE Translation, vol 10, doc 66, p 201). Slightly uneven toning, a few spots in upper margin, two-hole punch at left margin, folding creases.

In den WarenkorbAltogether 3 pp. 4to. Approximately 28 x 22 cm. An extraordinary testimony to the intellectual friendship between Albert Einstein and the mathematician Ludwig Hopf during the decisive months immediately before and after Einstein's emigration from Germany. The letters reveal cosmological reflections, personal humour, and Einstein…'s early warnings concerning the rise of National Socialism and the fate of Jewish scholars.The correspondence is addressed to Ludwig Hopf (18841939), Einstein's former assistant, whom he had first met at the ETH Zürich in 1910 and with whom he maintained a lasting scientific and personal relationship since their years together in Aachen. The letters document Einstein's cosmological thinking, his demanding international lecture schedule, and his increasing concern for the future of intellectual life in Germany under the Nazi regime.In the letter of 25 June 1932, Einstein explains the transition from a static to an expanding cosmological model, dispensing in this "first approximation" with both the cosmological constant and spatial curvature: "Seitdem man aus den Beobachtungen der Rotverschiebungen der extragalaktischen Nebel weiß, dass die Materie expandiert kann man den Gleichungen schon ohne -Glied und ohne Krümmung genügen" ("Since observations of the redshifts of extragalactic nebulae have shown that matter is expanding the equations can already be satisfied without the -term and without curvature"). Consequently, "man über die Existenz einer Raumkrümmung vorläufig nichts aussagen kann" ("for the present nothing can be said about the existence of spatial curvature").Alongside these scientific reflections, Einstein offers characteristically dry personal humour: "Die guten Berichte über Ihre Kinder freuen mich sehr Mir gehts auch ähnlich mit meinem jüngsten Sohn, der in der Musik ziemlich modernistisch verseucht ist. Der Ältere hat mich sehr respektlos zum Grosspapa befördert" ("The good reports about your children delight me greatly It is similar with my youngest son, who is rather infected with musical modernism. The elder has most disrespectfully promoted me to grandfather"). He also complains of having no time left for "Vergnügungs-Eskapaden" ("pleasure escapades").In the letter of 8 September 1932, Einstein apologizes for failing to answer an invitation, attributing this to the restless pace of his life during the final year of the Weimar Republic: "Zur Entschuldigung kann nur das Nomadenleben dienen, das ich in den letzten Monaten geführt habe" ("The only excuse can be the nomadic life I have led in recent months"). He regrets being unable to undertake a proposed lecture series because of his overwhelming travel obligations shortly before leaving Germany permanently in 1933.Particularly remarkable is the letter of 16 May 1933, written shortly after Hitler's seizure of power and Einstein's definitive break with German institutions. Attempting to help Hopf who would only succeed in emigrating to Cambridge in 1939 before receiving an appointment at Trinity College Dublin Einstein proposes an alternative professional future through international public lectures: "Sie sollen populäre Vorlesungen in verschiedenen Ländern und Städten über Relativitätstheorie, die Prinzipien der Hydrodynamik (Theorie des Fliegens), sowie über die Wandlungen der Atomtheorie halten" ("You should give popular lectures in various countries and cities on relativity theory, the principles of hydrodynamics [the theory of flight], and the transformations of atomic theory"). Such work, Einstein remarks, would not only be more profitable than a professorship but would also provide "ein amüsantes Zigeunerleben" ("an amusing gypsy life"). He offers to use his own international reputation actively on Hopf's behalf: "Sobald Sie es nur wollen, empfehle ich Sie überall hin, dass man Sie einladen soll" ("As soon as you wish it, I shall recommend everywhere that you be invited").Against the background of rapidly radicalizing.

In den Warenkorb1 p. 4to. 28 x 22 cm. A deeply personal and affectionate letter to Einstein's younger son Eduard ("Tetel"), inviting him to Caputh in the hope of cheering him and strengthening his spirits. Combining paternal concern, philosophical reflection, and intimate glimpses into Einstein's private life, the letter is among the most human… and emotionally revealing types of Einstein correspondence.Einstein writes that he will travel to Zurich on the 9th for "eine zionistische Sache" ("a Zionist matter") and proposes that Eduard accompany him back to Caputh, where he is living alone with Elsa in a small house by the lake: "Mein neues herrliches Schiff ist nun fertig und ich segle täglich. Es ist wunderbar für die Erholung" ("My splendid new boat is now finished and I sail every day. It is wonderful for recuperation"). Referring to the unusually cool weather, he suggests that the lakeside environment might benefit his son more than the mountains.The emotional core of the letter lies in Einstein's concern over Eduard's psychological condition and lack of vitality, which he senses between the lines of his son's recent letter: "Dein Brief bedrückt mich ein wenig, weil so wenig Unternehmungsgeist und Lebensfreude daraus spricht" ("Your letter depresses me somewhat because it shows so little enterprise and joy in life"). He stresses the moral and existential importance of meaningful work, invoking Arthur Schopenhauer as an example of a genius destroyed by the absence of practical occupation: "Selbst ein Genie wie Schopenhauer wurde zermürbt durch die Berufslosigkeit" ("Even a genius like Schopenhauer was worn down by the lack of a profession").Einstein continues with reflections of striking ethical clarity: "Man muss das Gefühl haben, dass man den anderen durch ehrliche Arbeit zurückgibt, was man empfängt. Sonst bleibt der moralische Katzenjammer nicht aus" ("One must feel that one gives back to others through honest work what one receives. Otherwise the moral hangover cannot fail to appear"). He concludes reassuringly that it will do Eduard good to spend more time in his company: "du wirst sehen" ("you will see").The letter was written during a transitional and physically fragile period in Einstein's life. Following a serious heart condition in 1928, he spent nearly a year recovering. In 1929 he built his celebrated summer house in Caputh near Potsdam, though at the time of the present letter he was still living in rented accommodation on Potsdamer Straße. The "new splendid boat" mentioned here was the sailing boat Tümmler, presented to Einstein by friends on the occasion of his fiftieth birthday in March 1929.Eduard Einstein (19101965), the second son of Albert Einstein and Mileva Mari , was highly gifted and musically talented. After excelling in his school examinations in 1929, he began medical studies with the intention of becoming a psychiatrist. Only a short time later, however, he developed schizophrenia, abandoned his studies, and spent much of his later life under psychiatric care at the Burghölzli clinic in Zurich.An exceptionally moving and psychologically revealing family letter, illuminating Einstein not as public icon or scientist, but as a deeply reflective and concerned father. From an important French private collection.

To the Polish German mathematician Chaim Herman Müntz (1884-1956), setting out several equations in the body of the letter: "Ich danke Ihnen bestens für die Mitteilung der a…llgemeinen Integrationsmethode für die Näherungsgleichungen, die zu der zweiten Hamilton-Invariante (Dichte) [.] gehört. Das ganze Problem liegt aber wesentlich schwieriger, als ich gedacht hatte [.] Damit hängt es zusammen, dass mir eine physikalische Interpretation der Theorie bisher überhaupt nicht gelungen ist. Es ist aber dabei im Auge zu behalten, dass gemäss Bohrs Resultaten der Zusammenhang zwischen der Bewegung der Singularitäten und dem Wellenfelde überhaupt nicht so einfach ist, wie es nach Maxwell sein sollte [.]". The letter closes: "Wenn ich wieder zurück komme, wollen wir ausführlich über die Sache reden. Man kann natürlich die ganze Bemühung als utopisch erklären. Aber eine mathematisch so natürliche Theorie ist ernsthafter Beachtung wert, zumal bei der gegenwärtigen disperaten Lage der theoretischen Physik" - a remark that appears to be levelled at the new developments in quantum mechanics. - A dense scientific communication from Einstein's Berlin period, aligning with his intensive work on a unified field theory in 1928-29 and reflecting his reliance on other figureheads of contemporary physics and mathematics. Müntz, noted for the Müntz approximation theorem, worked with Einstein from 1927 and is thanked in Einstein's paper "On Unified Field Theory" (1929) for "laboriously precise calculation on the basis of Hamilton's principle", underscoring the present letter's context. - A fine association piece at the intersection of physics and higher mathematics, documenting Einstein's ongoing attempts to ground unification in a Hamiltonian variational framework. - Folded horizontally and vertically; envelope torn open somewhat roughly at the side. - From a Swedish private collection. - The Collected Papers of Albert Einstein (Princeton UP, 2021), vol. 16, p. 389f., no. 245 (edited from a photocopy).

In den Warenkorb4to (280 x 216 mm). 1½ pages. Dated (likely in the hand of Helen Dukas) in pencil at upper and lower right. The manuscript comprises approximately 31 lines of mathematical workings. Einstein devoted the last thirty years of his life to the quest to combine general relativity and Maxwell's theory of electromagnetism into a single… physical and mathematical framework which would account for all of the then-known fundamental forces of nature - a "unified field theory". Although his early attempts in the 1920s focused on "distant parallelism", he later concentrated on an approach treating both the metric tensor and the affine connection as fundamental fields, often introducing an element of asymmetry (in variance to the theory of general relativity). Einstein often complained of the heavy mathematical burden imposed by this approach, as demonstrated in the present manuscript. - In mint condition. - Sotheby's, 30 May 1979, lot 49 (part).
