Last week we posted Part A of our blog, the goal of which was to provide recognition and historical documentation to what we identified as significant CRT product innovations and pioneers in the field of Wheelchair Seating and Mobility.

We have already heard from some of you offering additions to our list – thank you! We hope the suggestions keep coming, at Remember that NRRTS DIRECTIONS plans to publish an updated version of this list after we collect and research the feedback from the CRT community.

This week we move on to Part B, which is purely for fun!

Part B is our “Top 10” list of all-time CRT pioneers and their historic inventions. This list is of course subjective, and we hope it stimulates lots of conversation and maybe even a little controversy as you weigh in supporting or challenging our list. Let us know your own list, where you think we missed the mark, or innovations you believe deserve to be recognized in an all-time Top 10 list. You won’t offend us by disagreeing with our list – there are plenty of excellent contenders!
