Ruth Duorkin was born with quadriplegia caused by cerebral palsy. During her teens she received primitive neural interfacing to give her an electronic voice, and a powered exoskeleton when she was sixteen which allowed her to stand and eventually walk. Her experimental "bodywalker" system, a kind of hollow robot which encased her (largely inert)body was at first slow and difficult to control, but with better interfacing and naturally-occurring neural accommodation she was able to move freely by her mid-twenties. Her exoskeleton incorporated systems to maintain her muscle tone, but her skeletomuscular system was already atrophied beyond recovery.
Exoskeletons for military and industrial use were becoming more sophisticated during this period, but Duorkin was one of the first to be permanently linked, physically and neurotechnically, to such equipment. Many semi-artificial clades around the Terragen Sphere deem Duorkin to be among the first true cyborgs.
She became a campaigner for differently-abled peoples' rights around the world, and following an assassination attempt in Venezuela in 2032 c.e. she incorporated a discrete kevlar outer skin to her bodyplan. She also was subject to sporadic hacking and spambot attacks on her net-connected components, against which she designed ingenious defences.
When she died in 2090 c.e. her now highly electronic and versatile bodywalker was copied for the Smithsonian Institute as an example of early cyberhuman interfacing.
