A definitive scholarly edition of the correspondence and papers of Albert Einstein During the period covered by this volume, Einstein aims to discover whether one can derive the electron’s equations of motion directly from the field equations of general relativity, and he embarks on a new approach to unified field theory founded on teleparallel geometry. On these topics, he engages in exchanges with J. Grommer, C. Lanczos, and particularly with C. H. Müntz, and corresponds with mathematicians like R. Weitzenböck and É. Cartan. Einstein attends what will be considered a historic 1927 Solvay Conference where the new quantum mechanics is discussed, but in fact he makes very few remarks. In an important prelude to his eventual emigration to the United States, he is invited in September 1927 to accept a research professorship at Princeton University. Despite the sudden onset of a severe heart ailment in 1928, followed by an almost year-long period of convalescence, Einstein maintains a sustained engagement with scientific work, correspondence, and social and political issues. He publishes many articles and interviews designed for a popular audience and continues various technical preoccupations, including publishing a patent for a novel “people’s” refrigerator and being intimately involved in the design of his famous sailboat. Einstein advocates for domestic legislative reform, gay and minority rights, European rapprochement, and conscientious objection to military service. He resigns from his positions at the Hebrew University. He also tries to avoid the fanfare marking his fiftieth birthday in March 1929 yet is “buried under a paper avalanche” from the tributes. His hiring of Helen Dukas as his assistant, who accompanies Einstein to the end of his life, is of great significance for the ultimate preservation of his written legacy.

Well before Germany emerged as a single nation or chemistry as a clearly defined profession, German chemists had formed a national scientific community that presaged the increasing specialization so characteristic of modern science. It found a forum in the chemical journal established by Lorenz Crell in 1778. It proved its cohesiveness first by rejecting Lavoisier's theory on nationalistic grounds and then, after a fierce struggle, by rallying behind "the French system." This pioneering study of the early German chemical community is rich in implications for the social history of science. Charts, tables, graphs and illustrations.

With The Archive of the Sing-Akademie zu Berlin. Catalogue a complete catalogue of the music archive of the Sing-Akademie zu Berlin is now available for the first time since the archive, which disappeared during World War II, was rediscovered in 1999. (The whole work is complete in English and German). Since 2001 the more than 260,000 pages of music manuscripts, copies and first prints (from 17th to early 19th cent.) were revised by two musicologists which compiled an index of shelf marks and an index of composers. Thus detailed searches in the holdings of the archive (which were filmed since 2002 in severeal parts on microfiche at K. G. Saur) are possible for the first time. The Catalogue lists 9,735 works of 1.008 different composers. It provides also a concordance signature – microfiche and therefore serves as a cumulated guide to the microfiche editions, all the more the registers have been revised and improved. The unique collection is introduced by a number of articles by the following musicologists: Axel Fischer (Archive of the Sing-Akademie, Berlin), Christoph Henzel (Hochschule für Musik, Würzburg), Klaus Hortschansky (University of Münster), Matthias Kornemann (Archive of the Sing-Akademie, Berlin), Ulrich Leisinger (Mozarteum, Salzburg), Mary Oleskiewicz (University of Massachusetts Boston), Ralph-J. Reipsch (Zentrum für Telemann-Pflege und -Forschung, Magdeburg), Tobias Schwinger (Berlin).

The period of court absolutism and early capitalism extended from the end of the Renaissance to the Enlightenment. A new world view was created, along with a new type of individual possessing new economic orientations to the marketplace and new social attitudes deriving from such concerns. The unified political and religious world of medieval Europe broke into parts: national differentiation and religious options abounded. The autonomy of the nation-state created a need for new attitudes toward religious minorities, even despised ones such as the Jews. The court Jew phenomenon, as Selma Stern details, was inextricably linked to these larger developments, including the emancipation of Jews as a whole. Dr. Stern's work is an effort to reconstruct this unusual group of Jews who became politically and economically influential and through that mechanism were able to enhance Jewish community life as a whole. In his very existence the court Jew necessarily enlarged, beyond its original meaning, the concept of free expression in European societies.As the dominating idea of defending one church and one emperor collapsed under the weight of the new European system of power balances, a new conception of the Jew developed, one of a transforming agent in economic and political positions. With trade no longer condemned as sinful, collecting interest for loans no longer prohibited, and the merchant no longer compared to a thief, the Jewish money changer and tradesman came to be viewed in a more favorable light. In this new environment, the claims of Christianity remained supreme, but the rights of religious minorities were considered.At the time of the book's initial appearance, the Saturday Review hailed it as a "picturesque work giving evidence of great writing talent." The reviewer went on to note that "Dr. Stern's work provided exhaustive historical background of European Jewry - from 1650 to 1750 - that period during which the modern European genius emerged." Dr. Stern's work relies heavily upon European archives up to 1938, when the advances of Nazism made further work impossible. As a result, what was started in Europe was completed in America.
