Which would make me my own grandpa... but as an owner of the original 128k Mac, I can assure you that no one has the authoritive reason for 1.8 gamma on the Mac. But the most common, and a fairly convincing, story is that the early (300dpi, B&W) LaserWriter printers (which revolutionized publishing) had a dot gain that approximated the difference between 1.8 and 2.2, so using a 1.8 gamma would offer results that were about what they should be.
