| - | 🌐 J.C.R. Licklider — Computing’s Johnny Appleseed | + | Joseph Carl Robnett Licklider, known simply as “Lick,” was a psychologist and computer scientist whose ideas seeded the modern internet. Often called “Computing’s Johnny Appleseed,” he planted the concepts that others later turned into the ARPANET and, eventually, the global network we use today. |

Sorry if some of the pages having missing graphics or a bookmarked page is missing. We are migrating our site over to DokuWiki from Drupal. The last major overhaul of our site was in 2016, and we were due for some freshening up.
The collection of material for the study of geek history dates back to my early days in technology as far back as the 1970s. You will find specific footnotes and references on many pages with links to current websites. Anytime a claim is made, or a fact is stated from a website or blog that does not appear to have firsthand knowledge of the subject I make a note to follow up on it. I can assure you that anything I have written is based on verification of facts from a source as close to the events and individuals as possible or multiple sources of information from leading publications or references.
