This is a hefty one. I usually try to keep things as accessible as possible, but this time we have to get a little more technical than usual. We are picking up in 1964, with the first proposals for a new version of ALGOL. From there we sail through the fraught waters of ALGOL X, Y, W, and finally 68. Along the way we see how a language evolves over time, and how people and politics mesh with technical issues.
