INTERNATIONAL TABLES FOR CRYSTALLOGRAPHY Volume A1 SYMMETRY RELATIONS BETWEEN SPACE GROUPS Edited by ¨ HANS WONDRATSCHEK AND ULRICH MULLER Dedicated to Paul Niggli and Carl Hermann In 1919, Paul Niggli (1888–1953) published the first compilation of space groups in a form that has been the basis for all later space-group tables, in particular for the first volume of the trilingual series Internationale Tabellen zur Bestimmung von Kristallstrukturen (1935), for Interna- tional Tables for X-ray Crystallography Volume I (1952) and for International Tables for Crystallography Volume A (1983). The tables in his book Geometrische Kristallogra- phie des Diskontinuums (1919) contained lists of the Punktlagen, now known as Wyckoff positions. He was a great universal geoscientist, his work covering all fields from crystallography to petrology. Carl Hermann (1899–1963) published among his seminal works four famous articles in the series Zur systema- tischen Strukturtheorie I to IV in Z. Kristallogr. 68 (1928) and 69 (1929). The first article contained the background to the Hermann–Mauguin space-group symbolism. The last article was fundamental to the theory of subgroups of space groups and forms the basis of the maximal-subgroup tables in the present volume. In addition, he was the editor of the first volume of the trilingual series Internationale Tabellen zur Bestimmung von Kristallstrukturen (1935) and one of the founders of n-dimensional crystallography, n 3.
