The 4th ESLAS meeting moved to the ancient French port of Marseilles, under the presidency of Dr Benjamin Ascher, and was held from May 3 to may 5th 2001. more than 250 attendees enjoyed a wide range of topics from a very strong Faculty, consisting of 33 from Europe and 4 non-Europeans. The three days saw 8 round table sessions, and 30 free papers. A very extensive technical exhibition had the latest equipment on display. The congress was enhanced on the 2nd day by a presentation to Dr Mario Trelles from the Mayor of Marseilles. The food was of course delicious, and the social programme most elegant and very good fun.
