The Origins of Digital Computers
Author: B. Randell

Publisher: Springer Science & Business Media
Release Date: 2012-12-06
My interest in the history of digital computers became an active one when I had the fortune to come across the almost entirely forgotten work of PERCY LUDGATE, who designed a mechanical program-controlled computer in Ireland in the early I ':ICC's. I undertook an investigation of his life and work, during which I began to realise that a large number of early developments, which we can now see as culminating in the modern digital computer, had been most undeservedly forgotten. Hopefully, historians of science, some of whom are now taking up the subject of the development of the computer and accumulating valuable data, particularly about the more recent events from the people concerned, will before too long provide us with comprehensive analytical accounts of the invention of the computer. The present book merely aims to bring together some of the more important and interesting written source material for such a history of computers. (Where necessary, papers have been translated into English, but every attempt has been made to retain the flavour of the original, and to avoid possibly misleading use of modern computing terminology.
The Typewriter Revolution: A Typist's Companion for the 21st Century
The connoisseur's guide to the typewriter, entertaining and practical What do thousands of kids, makers, poets, artists, steampunks, hipsters, activists, and musicians have in common? They love typewriters—the magical, mechanical contraptions that are enjoying a surprising second life in the 21st century, striking a blow for self-reliance, privacy, and coherence against dependency, surveillance, and disintegration. The Typewriter Revolution documents the movement and provides practical advice on how to choose a typewriter, how to care for it, and what to do with it—from National Novel Writing Month to letter-writing socials, from type-ins to typewritten blogs, from custom-painted typewriters to typewriter tattoos. It celebrates the unique quality of everything typewriter, fully-illustrated with vintage photographs, postcards, manuals, and more.
When Computers Were Human

Before Palm Pilots and iPods, PCs and laptops, the term "computer" referred to the people who did scientific calculations by hand. These workers were neither calculating geniuses nor idiot savants but knowledgeable people who, in other circumstances, might have become scientists in their own right. When Computers Were Human represents the first in-depth account of this little-known, 200-year epoch in the history of science and technology. Beginning with the story of his own grandmother, who was trained as a human computer, David Alan Grier provides a poignant introduction to the wider world of women and men who did the hard computational labor of science. His grandmother's casual remark, "I wish I'd used my calculus," hinted at a career deferred and an education forgotten, a secret life unappreciated; like many highly educated women of her generation, she studied to become a human computer because nothing else would offer her a place in the scientific world. The book begins with the return of Halley's comet in 1758 and the effort of three French astronomers to compute its orbit. It ends four cycles later, with a UNIVAC electronic computer projecting the 1986 orbit. In between, Grier tells us about the surveyors of the French Revolution, describes the calculating machines of Charles Babbage, and guides the reader through the Great Depression to marvel at the giant computing room of the Works Progress Administration. When Computers Were Human is the sad but lyrical story of workers who gladly did the hard labor of research calculation in the hope that they might be part of the scientific community. In the end, they were rewarded by a new electronic machine that took the place and the name of those who were, once, the computers.
