John Graham-Cumming

John Graham-Cumming is a wandering programmer who's lived in the UK, California, New York and France. Along the way he's worked for a succession of technology start-ups, written the award-winning open source POPFile email program and churned out articles for publications such as The Guardian newspaper, Dr Dobbs, and Linux Magazine. His first effort writing a book was the obscure and self-published computer manual GNU Make Unleashed which saturated its target market of 100 readers. Because he has a doctorate in computer security he's deeply suspicious of people who insist on being called Dr., but doesn't mind if you refer to him as a geek. He is the proud owner of a three-letter domain name where he hosts his web site:

--Steve Mirsky, Scientific American

"I recommend this book for any of you that travel and are looking for some great places to visit and also those that are armchair travelers. Loads of interesting information here to read."
--Virginia Chilcote, Bay Area MUG-Florida, October 2009 MouseBytes

"Even if you consider yourself not a geek, The Geek Atlas might just bring out the geek in you that you’ve never known, or even turn you into one. And that isn’t a bad thing."
--Dominique James, Sacramento Book Review

"Graham-Cumming's guide book covers everything from where Newton's apple fell to the pub where Watson and Crick announced they'd unlocked the secret to DNA. He also has a handful of entries specific to computers."
--Dan Tynan, InfoWorld

"So if you're planning a summer break in the UK this year, whether because of the financial situation, your desire to reduce your C02 output or just because it's a lovely country, you should pack The Geek Atlas along with your National Trust handbook and good hotel guide. "
--Bill Thompson, BBC News

"...a fascinating and enjoyable read; in fact, it I found it hard to put down. "
--Ben Rothke,

"Geek hobbyists don't need to travel the world to enjoy the book. They will be equally content to delve into The Geek Atlas on a rainy Saturday and enjoy the generous technical examples and stories of these fascinating museums of science and technology. "
--Helen Gallagher,

"So whether or not you happen to be a self-confessed geek or a fully-fledged scientist, Graham-Cumming's guide is well worth investing in."
--Adam Hartley, BBC Technology/

"I seldom own a book that makes my fellow geeks here at PC World go wild when I show it to them, but John Graham-Cumming has done the trick with The Geek Atlas: 128 Places Where Science and Technology Come Alive, available in both dead-tree and digital formats."
--Anne B. McDonald, PC World

"HEADING abroad? Don't forget The Geek Atlas. "
--Celeste Biever, New Scientist

"I've been reading The Geek Atlas: 128 Places Where Science and Technology Come Alive, and now I've got all kinds of ideas for avoiding the likes of Disneyland or, here in Seattle, this weekend's Fremont Solstice Parade...The book's a starting point rather than a comprehensive guide, but its nerd cred is real..."
--Angela Gunn, Betanews

"The Geek Atlas reads like a textbook that's actually fun to flip through — it's incredibly informative, accessible, and challenging. It's a collection of some of the most important sites — and therefore the most important thoughts — our culture has to offer. "
--John Baichtal, GeekDad

"The genius of this book lies in the science with the travel destinations acting as an added bonus. This book now has a spot in my knapsack and I look forward to The Geek Atlas 2."

"Here’s a three word summary review for you: “Cool Book. Buy.” "
--Jeff Katz,

"I really enjoyed this 'atlas'. In fact, while reading it on the train, a fellow passenger kept eyeing the book. I offered it to him to peruse and he thumbed through it with vigor and deep interest for most of the duration of the ride into Chicago. I have read plenty of technical and scientific books on the train, but this was the first time in all the years I have been commuting by rail that a fellow passenger took that much interest in a book I was reading. This further reinforced for me just how compelling and well written The Geek Atlas is, and why anyone who enjoys technology and traveling should buy this book before setting off on any vacation adventure. "
--Mike Riley, Dr. Dobb's CodeTalk

"The Geek Atlas is a great geography and history of science and technology. It's not overly technical but includes a lot of scientific explanation as well as information on the fascinating 128 scientific destinations. It's not just for armchair readers, it's a proper travel book, as well."
--Simon Jary, PC Advisor
