I had the privilege of working with Don back at JPL at the time he invented the rocker bogey. (I wrote the software for the first prototype with a computer on board.) Not only was he brilliant, he was also a really nice guy. I didn't appreciate at the time how rare that combination of traits is among humans.
To my astonishment, it turns out Don doesn't have a Wikipedia page (though the rocker bogie suspension does).
Thanks for pointing out the rocker-bogie Wikipedia page. There's a true dearth of info about them. Do you happen to know if there's any kinematic analyses of these suspensions available? I used to do stress analysis in the aerospace industry and I've been interested in that sort of analysis since the 1997 Sojourner rover.
He really deserves a page, in the engineering world this is as notable as it gets. The number of skills casually on display here. Just wow.
