Lachlan Cranswick (1968-2010) was well known to members of many communities within the structural sciences, including powder diffractionists, crystallographic computer scientists, and educationalists. He was an extraordinarily enthusiastic proponent of the free exchange of information, and an inveterate cataloguer, collector and disseminator of information, software and teaching resources.
In the late 1990s Lachlan began to create CD-ROMs containing collections of useful crystallographic and other software (one of his projects involved software from current 'artificial life' projects). These were sent to individual crystallographers he knew who had limited or no Internet access - usually, but not invariably, in developing countries.
