I had the honor of knowing Bill Dobelle for more than 25 years. With his ever-present bowtie, he was enamored with bringing sight to the blind (which number about 15 million people around the world). I am sure if he hadn’t died prematurely at 64, he would have succeeded completely. As it was, he managed to enable those who had lost their sight to recognize shapes, patterns, and colors, using a series of implanted electrodes.
