With Issue 1 of Volume 100 we start the celebration of the one-hundred-years jubilee of the Zeitschrift für Mathematik und Mechanik – Journal of Applied Mathematics and Mechanics (ZAMM) which was founded in 1921 by Richard von Mises, together with its society GAMM (Gesellschaft für Angewandte Mathematik und Mechanik: International Association of Applied Mathematics and Mechanics). In his first paper in the ZAMM “An Introduction: On the Problems and Goals of Applied Mathematics”,1 von Mises underlined the necessity to combine mathematical research with practical problems. This was something new – instead of the differentiation of “pure” and “applied” mathematics to have a view on practical (here industrial) needs as well. Up to now, this question remains a challenge. This 100th Volume starts off with a brief history of the ZAMM. Starting with Issue 2, each issue will contain a “historical paper” showing the uniqueness of some research the previous time, especially with respect to the publication language. For a long time, German was the publication's language: not only because the ZAMM was originally founded in Germany, but because in those earlier decades German was considered an international language in Science and Engineering. Seeing as now English is the main scientific language, some papers were translated for this jubilee volume. In Issue 2 our readers can find the translation of the first paper of Richard von Mises and in Issue 3 we will have the translation of a famous paper of Heinrich Hencky from 19242 with a contemporary commentary of Otto T. Bruhns. New discussions in the mathematical field in around 1920 is where the history of ZAMM begins. After the World War I certain engineers started paying attention to Engineering Mechanics, which simultaneously should be science-based as well as being useful for industrial practice. In the Berlin branch of the VDI (Verein Deutscher Ingenieure: Association of German Engineers) the annual report 1919/1920 stated that several committees with a focus on Engineering Mechanics and Physics should be organized. Lectures in these committees were devoted to various topics belonging to Mechanics and Mathematics, but there were no possibilities to publish the results in both fields in a common journal. In a Board meeting of the VDI on September 19th, 1920 the need of such a journal was finally discussed: after the meeting it was announced that from 1921 the new journal ZAMM will be published with 6 issues per year. In addition, the VDI offered Richard von Mises to take on the position of the Editor-in-Chief. The journal would be published by the VDI Publishing House in Charlottenburg, in what is modern-day Berlin. It should be noted that in this economical time the VDI Publishing House was financially faring so well that the decision for the founding of a new journal was made without any long discussions. In these first years, the journal carried the subtitle ‘Ingenieurwissenschaftliche Forschungsarbeiten’ translating to ‘engineering research papers’. During the first decennium of its existence, the ZAMM became well established in the scientific communities. The quality of the papers was so high that, starting 1931, the journal was reprinted by Johnson Reprint Cooperation (New York, N.Y.) with permission of the original publisher. Looking back on the history of the ZAMM one can tell that it has not always been easy to keep the journal going. After more than 10 volumes, the first trouble started in 1933 when the founding editor Richard von Mises stepped down and emigrated, and with that, ZAMM somewhat losing its professorial status. At the end of the World War II the publication was closed for financial reasons. After the war, every journal needed to get permission from the confederate administration to enable any kind of publication. The re-start of the ZAMM was organized by the Akademie-Verlag in the East of Germany and Issue 1 of Volumes 25/27 was published in April 1947. The formation of the journal during the next 45 years was successful but not always easy, seeing as its GAMM society was based in the western part of Germany. Contact between the board members up to 1961 was often limited or impossible, which made it very difficult to organize any collective work within the board. After 1990 an economic crisis hit again caused by the unification of the former East and West Germany: in 1991 publisher Akademie-Verlag crashed, which put the journal's future in danger. This time the troubles fortunately did not last long. In that same year, the VCH-Verlag from Germany obtained the nature sciences program which included all mathematical titles and so ZAMM could continue its publications. In 1996, John Wiley & Sons acquired VCH-Verlag and all its imprints. The agreement with Wiley has been so fundamental that the cooperation with Wiley is stable up to this day. To understand the history of the ZAMM, one should look at both the organization principles and the acting persons (Table 1). Please note that there was no ability to get a complete set of documents from both the society and the publisher – during World War II and the troubling 90ies many things were lost. Any additional information on the history of ZAMM is welcomed.1 In addition, a Managing Editor was introduced (P. Maaß, 1997-1997; H. Altenbach, 2004–2012; B. Platzer, 2012–2017).
