What is the history of modding

I am making this topic to honor the brave first who pioneered modding when I was but a wee infant, so very long ago... Thank you to all the Admins who have been nerfing since the 2000s. So, this topic is about if you can give me dates and a backstory of when a new "First" was achieved. So if you could tell me when the first coupler mod was done, or when someone first made canted flywheels, this post is about when and where they happened. Thanks
