, one of the minerals he had collected in his youth. Despite having become highly Americanized, he found himself unable to resist an offer to return to ETH Zurich, in 1954, to fill the chair that had been left vacant by the death of his advisor Paul Niggli. He remained in Zurich until his retirement in 1976. Laves was the editor of the journal '' Zeitschrift für Kristallographie'' between 1955 and 1978, which honoured him with a special issue in May 2006 commemorating the hundredth anniversary of his birth. The issue was devoted to the crystal chemistry of intermetallic compounds and included two articles on Laves' contributions to crystallography.


Personal life

Laves was married to architect Melitta Druckenmüller (1907 – 1990), who assisted him with many of the illustrations in his publications. They had three daughters together, Gracia, Charlotte, and Katharina.
