I am working on a series of posters looking at different inventions that changed Cities. What “technologies” or inventions do you think have had the biggest impact on the city?

Electric water pump.
what a fun project. There are so many small or overlooked things that we take for granted that do make modern life, particularly urban life, possible. I’ve got a couple books and articles, including a great article on the history of Air Conditioning, that I’ll post in our reading library when I get to work and have the citations handy.

There is a book based off of a podcast called the 99% Invisible City. The book is really interesting and goes over some of the most important but overlooked aspects of a city. Go check it out

I remember the History Channel had a show about Cities that covered a lot of this stuff. Been at least 10 years. Don’t remember what it was called.

Refrigeration (esp. train cars) allowed people to move away from being close to food production sources (I.e. farms) and into cities.
