Brendan Davis started his career in 1959 as an apprentice with the Automatic Telephone and Electric Company (AT&E)—a pioneer of automatic telephone exchanges and radio communication systems in the UK. By the end of his apprenticeship he was running the test equipment maintenance and calibration department. He became interested in test technology, and left in 1966 to join the UK office of the General Radio Company—universally known as GR and revered by every radio amateur on the planet at that time. Founded in 1915, in Cambridge Massachusetts, to supply test and measurement equipment to the emerging radio broadcasting and communications industries, GR became the main pioneer of test and measurement and arguably one of the most influential companies of all time. Through close links with MIT and other universities, plus their own brilliant designers, they made most of the basic test equipment tools commercially available for the first time. Prior to GR if you needed to measure something you had to build your own measurement tools. The list of GR ‘firsts’ is huge but a brief selection includes the oscilloscope, the vacuum tube voltmeter, frequency standards and measurement, signal generators, RC oscillators, the sound level meter, audio analyzers, the stroboscope, microwave measurement tools and connectors and even the humble ‘Variac’ and ‘Banana Plug’. GR’s thirty-year association with ‘Doc’ Edgerton and his team at MIT, developing stroboscopes, is cited by many universities as the model for cooperation between academia and industry for the transfer of technology into viable products. GR engineers contributed the circuit design. There can be very few people that have not seen the Doc’s famous photographs of bullets passing through apples and playing cards, or of milk drops exploding into crown-like structures on impact. These photographs were taken using standard catalogue GR stroboscopes triggered by a GR sound level meter. Every electronic flashgun used on cameras and in photo studios worlwide owes its existence to this partnership. It was against this background of innovation that Brendan’s interest in testing grew. Yet another first for GR was the computer-based printed circuit board test system in 1969. Brendan immediately got involved with this exciting new product that quickly created a new market. He held a number of sales and marketing positions within the company, the name of which was changed to GenRad in the mid 1970s and is now part of Teradyne. Around 1979 he developed an interest in using an economic approach to decision making, following some pioneering work by a GenRad colleague—Dr James Faran. He then developed a training course on test economics which he presented at the Internepcon conference in Brighton, England. When another GenRad colleague, John Zapf, saw the course notes he suggested that Brendan expand on them to create a book. John also made the contact with the McGraw-Hill book Company that led to the first edition of ‘The Economics of Automatic Testing’ in 1982. At the time of publication Brendan was already a regular participant in conferences on electronics test throughout Europe and America and a regular contributor of article to technical journals. He also developed and participated in a regular series of seminars for GenRad, which were a major element of their educational programs, and did some guest lecturing at Brunel and Warwick universities in the UK. In 1992 he established his own consulting and training operation and used very detailed economic modelling to analyse the testing operations of clients and taught them how to apply the techniques themselves. He moved to Ireland in 1998 where he spent a few more years in the test arena. He retired a few years ago but keeps busy with a bit of consulting, a keen interest in photography and some promotional work.
