This volume, the 16th and last in the current series of reprints, is translated from the German original of 1925 and provides a very fine picture of the state of the mechanical calculator industry in 1925. After an introduction that describes the seven major types of machines that had been produced by 1925, Martin offers a list of specific makers, arranged by the date when they first patented or produced a calculating machine, and a quite detailed description of the devices themselves, many of which are illustrated.

The calculators that we see and use in today’s generation is quite different from the older ones. Their primary development and introductory innovation dates back quite decades back. The development of calculators or previously known as calculating machines is quite comprehensive. Their style of functioning and performance took some time to get to the current stage. Calculators tentatively have many advantages and therefore their usage and availability has been prominent from the beginning itself. The technical aspects are always dominant compared to others in a calculator. Every Calculator has varying levels of efficiency, with top to bottom. The concept of a calculator is very definite and its introduction in the technical system has many inevitable advantages. Calculators are known to be successful in reducing time-related complications and delays in the system of assessment or analysis. Every calculator has a certain deficiency factor, which is improved in its successor. These limitations may be unexpected errors or temporary failures due to excessive usage. Although, the number of failures in the recent times have been greatly reduced compared to the older times, the amount of progress made by technology in terms of user ease and accuracy, is remarkable.
This book by Mr. Ernst Martin is an invigorating and delightful read on how the effect of technical advancements caused the field of calculators’ innovation to change and emerge as a composite progress. This book also correlates on how the idea generation of Calculators was initiated and began to take shape, dodging and evading any possible hindrance or limitation. The Development of calculators, their older references, and their extension of purposes is all explained in this book. The overall progress and its impact on the user section is quite well related in this book, and it basically explained how hours of procedures were reduced to minutes, due to the technical progress. It also tells us the impact of calculators in a country wise section and its perception by the various sections of the society and the Government of the respective country. Ernst Martin wrote Die Rechenmaschinento address the issues and questions that the public had raised about the many calculating devices that were appearing on the market in the early 1920s. His little book is, in fact, a developmental history of calculating machines in catalog form -invaluable for collectors of old machines. The introduction describes the seven major types of machines that had been produced by 1925. The corpus of the book consists of a running list of specific calculating machines, arranged by the date the device was first patented or produced.
