My Take

Carl Sassenrath is the kind of figure I genuinely admire. Bringing true multitasking to personal computers through the Amiga kernel in 1985 was no small feat; he gave ordinary machines a capability we now take entirely for granted. Not content with one landmark, he went on to design the REBOL language, a collaboration environment, and a private messaging system. That is a restless, building mind that never stops shipping new tools. He is not a household name, but the conveniences we lean on daily rest partly on foundations he laid. I find that quiet, prolific craftsmanship far more impressive than fame.

Overview

Carl Sassenrath (born 1957 in California) is an architect of operating systems and computer languages. He brought multitasking to personal computers in 1985 with the creation of the Amiga Computer operating system kernel, and he is the designer of the REBOL computer language, REBOL/IOS collaboration environment, the Safeworlds AltME private messaging system, and other products.
