James Essinger (born 5 September 1957) is a freelance writer and British author of numerous financial and business management books, but he is better known for his non-fiction books. These include Spellbound: The Improbable Story of English Spelling [1] and his popular science book on the history of computing, Jacquard's Web. [2] Essinger is also the author, with Jovanka Houska, of The Mating Game, a novel set in the world of chess.
Born in Leicester (5 September 1957), Essinger was educated at Wyggeston Grammar School for Boys, Leicester, and at Lincoln College, Oxford, where he obtained an MA in English Language and Literature. [3] Although a competition-level chess player, Essinger chose to focus on his academic career rather than entering the world of professional chess. After university, Essinger went to Finland where he taught English and became fluent in Finnish. [4] [5]
Since 1984, Essinger has been a freelance reporter [3] [6] [7] and prolific writer of books, articles and other publications. [8] [9] [10]
In December 2015, Essinger founded 'The Conrad Press', a publishing firm in Canterbury, [11] publishing the first fiction works by various authors, including Peter Taylor-Gooby, and local historian Paul Crampton. The Conrad Press now has more than 400 books in print or in production.
Essinger's writing begun in finance, management and IT, but more recently focuses on historical books.
His book, Jacquard's Web, develops from his involvement writing a computer history book about Charles Babbage, [12] The Cogwheel Brain, with Dr. Doron Swade . [13] His own research starts earlier and covers the role of Jacquard's Loom cards (the idea which Babbage used for his first 'computers', the Difference Engine and the Analytical Engine ), which were the precursors of the first programming languages, a significance recognised by Babbage's friend, Ada Lovelace.
Jacquard's Web (2004) was named one of The Economist's Best Science and Technology Books of 2004 [14] [15] and one of the best books in Science and Technology for 2004 by Entertainment Weekly . [15] [16]
Essinger continues this interest in his biography of Ada Lovelace, A Female Genius: How Ada Lovelace Started the Computer Age (2013) [17] This book was published in the United States under the title Ada’s Algorithm (2014). In 2019 Essinger published a book about the friendship between Charles Babbage and Ada Lovelace, Charles and Ada: the computer’s most passionate partnership. [18]
A movie option has been bought to Ada’s Algorithm by Monumental Productions [19]
Essinger has also written the libretto and most of the lyrics for a new two-act musical about Ada Lovelace: Ada’s Algorithm, the Ada Lovelace musical. [20]
Spellbound: the true story of man's greatest invention (2005) explores the English language and how it has developed through the ages to the quirkiness of today. Essinger covers topics from the extended meanings of ancient Egyptian hieroglyphics, King Alfred the Great's promotion of Anglo Saxon English to influences on our contemporary language. [21] He discusses how English is a mongrel mix of languages from as diverse sources as Cornish, Finnish and Inuit, [22] and how it shapes the English people. [23]
Augusta Ada King, Countess of Lovelace, also known as Ada Lovelace, was an English mathematician and writer chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation.
The analytical engine was a proposed digital mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator.
Computer science is the study of computation, information, and automation. Computer science spans theoretical disciplines to applied disciplines.
Charles Babbage was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.
A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage. The name difference engine is derived from the method of divided differences, a way to interpolate or tabulate functions by using a small set of polynomial co-efficients. Some of the most common mathematical functions used in engineering, science and navigation are built from logarithmic and trigonometric functions, which can be approximated by polynomials, so a difference engine can compute many useful tables.
The Jacquard machine is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom. The machine was patented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740). The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design.
This article presents a detailed timeline of events in the history of computing software and hardware: from prehistory until 1949. For narratives explaining the overall developments, see History of computing.
Joseph Marie CharlesditJacquard was a French weaver and merchant. He played an important role in the development of the earliest programmable loom, which in turn played an important role in the development of other programmable machines, such as an early version of digital compiler used by IBM to develop the modern day computer.
The history of programming languages spans from documentation of early mechanical computers to modern tools for software development. Early programming languages were highly specialized, relying on mathematical notation and similarly obscure syntax. Throughout the 20th century, research in compiler theory led to the creation of high-level programming languages, which use a more accessible syntax to communicate instructions.
Joseph Clement was a British engineer and industrialist, chiefly remembered as the maker of Charles Babbage's first difference engine, between 1824 and 1833.
The Lovelace Medal was established by the British Computer Society in 1998, and is presented to individuals who have made outstanding contributions to the understanding or advancement of computing. It is the top award in computing in the UK. Awardees deliver the Lovelace Lecture.
The history of computer science began long before the modern discipline of computer science, usually appearing in forms like mathematics or physics. Developments in previous centuries alluded to the discipline that we now know as computer science. This progression, from mechanical inventions and mathematical theories towards modern computer concepts and machines, led to the development of a major academic field, massive technological advancement across the Western world, and the basis of a massive worldwide trade and culture.
Conceiving Ada is a 1997 film produced, written, and directed by Lynn Hershman Leeson. Henry S. Rosenthal was co-producer of the film. The cinematography was by Hiro Narita and Bill Zarchy.

The Innovators: How a Group of Hackers, Geniuses, and Geeks Created the Digital Revolution is an overview of the history of computer science and the Digital Revolution. It was written by Walter Isaacson, and published in 2014 by Simon & Schuster.
The Thrilling Adventures of Lovelace and Babbage: The (Mostly) True Story of the First Computer is a steampunk graphic novel written and drawn by Sydney Padua. It features Ada Lovelace and Charles Babbage in an alternative universe where they have successfully built an Analytical Engine and use it to "fight crime".
Note G is a computer algorithm written by Ada Lovelace that was designed to calculate Bernoulli numbers using the hypothetical analytical engine. Note G is generally agreed to be the first algorithm specifically for a computer, and Lovelace is considered as the first computer programmer as a result. The algorithm was the last note in a series labelled A to G, which she employed as visual aids to accompany her English translation of Luigi Menabrea's 1842 French transcription of Charles Babbage's lecture on the analytical engine at the University of Turin, "Notions sur la machine analytique de Charles Babbage". Lovelace's Note G was never tested, as the engine was never built. Her notes, along with her translation, were published in 1843.
