Simplified Spelling Society
You Americans out there who are cringing should remember that one of the reasons we have American spellings of words such as theater, honor, and catalog is that luminaries including Noah Webster, Mark Twain, Benjamin Franklin, Andrew Carnegie, and Theodore Roosevelt advocated for simplified spelling, and many of them also supported simplified spellings of words such as though (tho), through (thru), and night (nite), which of course haven't taken on the cloak of wide acceptability. Roosevelt even tried to mandate that government documents use the simple spellings during his presidency. His proposal was ahead of its time and rejected by Congress, but some of his suggested simplifications have become the current standard spellings (1, 2, 3, 4). The British Simplified Spelling Society, which was founded in 1908—two years after Roosevelt's failed attempt to change spelling in America—still exists, and they often make the news when they protest at the Scripps National Spelling Bee (5).
