It is worth noticing five out of these fourteen speakers were "students" at the Erice Direct Methods course in 1974

A serious scientific anniversary and the shock provoked by celebrating the fifth course.

Telegrams were sent to David Harker, Medical Foundation, Buffalo and John Kasper, General Electric, Schenectady, with the words :
Thirty years after your pioneer work crystallographers at Direct Methods School Erice Sicily send their sincere greetings

Due to colds and coughings gathered during previous meetings, to celebrate the fifth crystallographic event participants were donated a wool scarf made in Erice, as a souvenir; in order to encourage them to wear the scarf, the organizers thought to stick sheets at the walls in Erice with a as warning "Crystallographers, protect your neck!"
After the meeting, biophysicists came for their school and watching those warnings still hanging at the walls, were asking themseleves what sort of dangerous life crystallographers had been experiencing few days earlier.
