The above has been extracted from the announcement printed by the Majorana Centre months before the meeting started. The actual lectures had often different titles and are "buried" into three volumes of collected lecture notes as witnessed by this photo; later, Oct 2009, Lachlan Cranswick has suggested that - to honour Isabella - a link to her contribution to awareness for Direct Methods should be available (look for Addendum A and care, 40 Mb due to 90 pages .pdf reproduced for Erice 1978 plus a shorter one, a published papers collection, only 10 pages .pdf, Erice 1984). Isabella insisted on determining phases in cascade by hand, a very efficient way to teach; on a more relaxing note, Jerry's photo reminds participants how, after dinner, the Karles were challenging the younger couples dancing cheek-to-cheek in the Madonna room.
It is worth noticing five out of those fourteen Direct Methods experts were "students" at the very first Erice course in 1974


A serious scientific anniversary and
the shock provoked by celebrating the fifth Erice 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 Erice 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 had sticked sheets at the walls in Erice with a warning "Crystallographers, protect your neck!"
Soon after the meeting, the biophysicists came for their school and watching those sheets still hanging at the walls, were asking themselves what sort of dangerous life crystallographers had been experiencing few days earlier.

You can distinguish, on their knees, from left Jama (from Somalia), Vincenzo Pavone, Ton Spek appearing just behind, ???, Ivan Vickovic, ???, ???, Isabella Karle, then four ???, Lodovico; first row standing Elizabeth Holt, Peter Main, Aris Terzis, Carmelo Giacovazzo, Giuseppe Allegra, ???, David Sayre, Jerry Karle, ???, and on top of David you see Ingrid Kjoller Larsen, behind her, end row, Michael Woolfson and on her left, Paul Beurskens; scarcely behind Giuseppe, Erich Haedicke; in the staircase, on first step, Fernando Mazza and Pinola Savalli, two-three steps up the stairs you see Davide Viterbo and further Paola Spadon with Otto Jarchow just behind, and David Watkin on his left. Two heads up behind Paola, Henk Schenk; on his right, one step up, along the iron banisters, Lesley Smart with long black hair; one further step up, above Henk, Clive Briant

However, on Oct 27, 2009, Lachlan Cranswick, via Anthony Spek, has forwarded an almost complete list for name allocation. Anthony is here hearthfully acknowledged with thanks. A better view of the above name allocation has been made available by Lachlan on Nov. 27, 2009, at http://www.iucr.org/resources/commissions/crystallographic-teaching/newsletters/3
