Who was the one armed driver?

Ok, something is driving me nuts, which admittedly requires only the minimum fare. In my floating around the web last month and reading up on Porsches I came across the account of an early driver from the 50's or early 60's who raced and won repeatedly but had only one arm. Of course now I can't find it anywhere.
I may be mistaken and have the wrong make of vehicle, but don’t think I am. Does this sound familiar to anyone?
Thanks,
Mark
