It’s all change at AT&T Unix Europe, after the departure of marketing manager Ray Sheath to become UK Managing Director of IBM communications specialist Adacom, and of technical chief Ely Lamb who has returned to the US after 30 months. In come two more US AT&T staff, Ed Chatlos to handle the sales and licensing side, and Sue Pickus, formerly supervisor of the Language System Engineering Group at AT&T Bell Laboratories to head the technical staff. Unix Europe Ltd, formed 30 months ago as a joint venture between AT&T and Olivetti to promote Unix in Europe, also says that it is expanding, with 25 staff on board and another two or three technical staff due to start at the firm in a few weeks.
