Lyons and Company teashops and retail outlets. Run weekly from that point on, this was the first time a computer program had been used for a strictly office related task. Most unusually, from the perspective of those who have been fed the standard history of computers, the machine on which this program ran was not built by the military or a large government department, but by the catering company itself: LEO, the Lyons Electronic Office. North American audiences may wonder why a restaurant chain would try to place itself on the cutting edge of information technology. Lyons, in post-war Britain, held a position somewhat equivalent to that of the McDonald's fast food empire in the present day, with fewer jokes about the quality of the food. As McDonald's is known for its distribution system, so Lyons had built a foundation of production automation and advanced business management. A 1947 trip to the United States, in fact, resulted in no lessons they could take from American companies, but did raise interest in the possible uses of the new "electronic brains." (An appendix reproduces the trip report from that visit, with an amazingly detailed primer on the state of the computer art.) The first LEO was, in a sense, a victim of its own success. Jobs were undertaken for outside enterprises (including calculation of ordnance data for the military) and there was increased demand from within the company as well. A subsequent generation of machines was built, and LEO Computers Ltd. was created in hopes that sales might be made to other companies. These orders did come, and the programming done by LEO staff resulted in a very early (and successful) form of expert system for a steel manufacturer. The company ran computer service bureaus and installed computers on three continents. Eventually, through mergers, both the company and the LEO architecture disappeared. The first part of the book is a basic history of the computer and company. With spare, readable prose it recounts the outline of people and actions involved. While less personal than some other histories written by the participants, it is also free of the more egregious forms of chauvinism that tend to characterize them. As a part of computer history, and as one that claims a unique position, it is rather odd that very little mention is made of computer developments in other companies of the time. The lack of hard evidence makes it difficult to accept the infrequent but invariable position that the LEO was the most cost effective solution in every competition. Parts two, three, and four rectify the lack of personality by including reminiscences from early pioneers, later workers, and those who dealt with sales abroad. While differing in style, all these reports are readable and interesting. (One item to note that is not strictly part of the book is the list of contributors at the beginning. As you read through the short biographies of the people involved in LEO there are a number who went on to major roles in British, European, and international computing. However, of more interest is the wide range of "extra-curricular" activities and contributions.) Because of its position in computer history, this book will undoubtedly be a fixture on the shelves of historians of technology. For those with any interest in the subject, it is also a jolly good read. However, the text provides more than its simple and inherent interest. The LEO was built and programmed by a group with a very different background from those who commonly created computer companies, and particularly those from the US. This unconventional outlook provided a distinct style that has much to teach those active in the field today. copyright Robert M. Slade, 1998 BKLEOFBC.RVW 980802
