An author of almost sixty books, with topics ranging from interiors to furniture history, from industrial design to the use of plastics, Gloag was a member of an elite design culture that was highly visible throughout the 1930s and 40s.
Reviews of the original edition of The Missing Technician: ‘The book is a reminder of the practical importance of good design in manufacture.’ The Time, Trade and Engineering Supplement ‘The book has left us with the impression that the success of some well-known British and American enterprises is due in no small measure to the employment of industrial designers.’ The Foundry Trades Journal ‘Mr. Gloag’s proposition is that industrial design is…a business operation, and as such can be costed: controlled, and aligned with sales policy, directed to home and foreign markets.’ The Sheffield Telegraph.
