As this thesis aims to offer some insight into their lives, it includes their biographies, highlighting their individual contributions to the congress. Furthermore, it explains why Zurich was chosen as the first host city and how the committee proceeded with the congress organisation. Two of the main organisers were the Swiss geometers Carl Friedrich Geiser (1843-1934) and Ferdinand Rudio (1856-1929). In addition to the congress, they also made valuable contributions to mathematical education, and in Rudio’s case, the history of mathematics. Therefore, this thesis focuses primarily on these two mathematicians. As for Geiser, the relationship to his great-uncle Jakob Steiner is explained in more detail. Furthermore, his contributions to the administration of the Swiss Federal Institute of Technology are summarised. Due to the overarching theme of mathematical education and collaborations in this thesis, Geiser’s schoolbook Einleitung in die synthetische Geometrie is considered in more detail and Geiser’s methods are highlighted. A selection of Rudio’s contributions to the history of mathematics is studied as well. His book Archimedes, Huygens, Lambert, Legendre is analysed and compared to E W Hobson’s treatise Squaring the Circle. Furthermore, Rudio’s papers relating to the commentary of Simplicius on quadratures by Antiphon and Hippocrates are considered, focusing on Rudio’s translation of the commentary and on Die Möndchen des Hippokrates. The thesis concludes with an analysis of Rudio’s popular lectures Leonhard Euler and Über den Antheil der mathematischen Wissenschaften an der Kultur der Renaissance, which are prime examples of his approach to the history of mathematics. 7 8 Acknowledgements Firstly, I would like to thank my supervisors, Prof Edmund Robertson and Dr John O’Connor, for taking me on as a research student. Their knowledge, experience, and words of advice and encouragement were invaluable during the past four years. A big thank you also goes to Dr Colva Roney-Dougal for officially supervising me – without her support my PhD would not have been possible. I would like to thank all those who helped me along the way by providing information, pointing out sources, and generally offering advice. They are too numerous for me to name them all individually, but I am grateful for all their contributions as each of them added a little piece to the jigsaw puzzle that is this thesis.
