In this week's Observer, a heartfelt obituary from John Naughton for Michael S Hart, founder of the Gutenberg Project, and inventor of ebooks:
Those who knew him testify that Michael Hart was an extraordinary individual – idiosyncratic, original, humane, determined and generous to a fault. He never made much money, repaired his own car, had scant faith in medicine and built most of his own electronic gear from stuff he picked up in garage sales. On Saturday mornings over breakfast in the local diner, he would work out the optimum route to cover the maximum number of garage sales that day; it was his version of the travelling salesman problem in mathematics.
In his obituary of Hart, his colleague Gregory Newby described him as an "unreasonable" man, in George Bernard Shaw's celebrated use of the term. "Reasonable people," wrote Shaw, "adapt themselves to the world. Unreasonable people attempt to adapt the world to themselves. All progress, therefore, depends on unreasonable people."
So farewell Michael Hart, the genius who freed up literature
