This is the javascript dude that isn't Brendan Eich right? I vaguely remember him from his JavaScript book that sits dusty on my bookshelf

I similarly didn't know much about him beyond being the JSON/JS-book guy, but found this podcast episode very enjoyable https://corecursive.com/json-vs-xml-douglas-crockford/ in which he details a cool career. Recommended listen when you have the time.

The same. Also the one who spec'd JSON.
