About the book

The famous inventor Zangemann lives in a huge villa high above the city. Adults and children alike love his inventions and are desperate to have them. But then something happens: when Zangemann wants to take another close-up look at his inventions during a walk through the city, a child hits him in the shin with the skateboard. That hurts! Enraged, the inventor makes a momentous decision... The clever girl Ada sees through what is going on. Together with her friends, she forges a plan.

This illustrated children's book tells the story of the famous inventor Zangemann and the girl Ada, a curious tinkerer. Ada begins to experiment with hardware and software, and in the process realises how crucial it is for her and others to control technology.

A book that arouses children's interest in tinkering and encourages shaping technology.

The book is currently available in German by the publisher O'Reilly Germany / Dpunkt Verlag (affiliate link - the FSFE gets 12%) and can be ordered from your preferred book store with the ISBN 978-3-96009-190-5.

We are working on an English version. As soon as the English version is done, we would be interested in more translations. If you want to help us with enabling professional published translations, reach out to us.

Amelia, 6 years, was one of the test readers of the book Ada & Zangemann. As there were no illustrations yet at that time, she painted it herself.

We would love to publish pictures of paintings or other things that children created about the book. In case your child painted an own version of Ada or Zangemann, a modified skateboard, how they imagine software, or how computer who print ice cream could look like in future. Please e-mail them to us including the permission for us to publish them under either CC-0 or CC-BY-SA.
