Top: The SGTK research focus topics through time, compiled and simplified from the Geotechnical Series topics illustrated in Fig. 11. Bottom: Chronological overview of the SGTK presidents. All presidents were professors at Earth Sciences institutes at ETH Zurich except A. Von Moos. Their presidential terms were: U. Grubenmann 1899–1924, P. Niggli 1924–1948, F. de Quervain, 1949–1974, A. von Moos 1975–1977, V. Trommsdorff 1978–1983, C. Schindler 1984–1995, V. Dietrich 1996–2007, M. Schmidt 2008–2013, C. Heinrich 2014–2018. Note the apparent coincidence of the three first presidency terms with the two main research focus topics (1. hydrocarbons, natural stones, clays, 2. metalliferous ores) during the first ca. 75 years
