Morgan Worthy (
http://mworthy.home.mindspring.com/) originated the
puzzle form now called "linguistic equations" or "DITLOIDS" (see entry for 1, below). The first ones were published in his 1975 book, "AHA! A Puzzle Approach to Creative Thinking" (Chicago: Nelson Hall) - now out of print.
Here are his comments on how he thought of the idea in the first place, and why they have become such perennial favorites:
I got the idea for linguistic equations from graffiti someone had
written in the form of an obscene formula on a restroom wall at the
University of Florida. When the answer suddenly came to me, I realized
the format was a good one for eliciting the "aha effect". After that I
used such items as exercise material when teaching workshops on
creative thinking.
My guess is that one reason a person enjoys linguistic equations is
that the answer hits him or her all at once rather than being solved in
an incremental fashion. It is similar to what happens when we suddenly
see an embedded figure pop into focus; the satisfaction is visceral
rather than just intellectual. My experience was that people often had
the answer to an item come to them when they were not consciously
thinking about the puzzles, but relaxed, such as in the shower or about
to fall asleep.
Another factor is that with well-written items, success does not hinge
on obscure information. Ideally, a person should never have to feel, "I
could never have gotten that one no matter how long I worked on it."
There is something ego enhancing about knowing you have the answer
inside and just need to find it.

This puzzle form reappeared as 24 "equations" by Will Shortz, printed in the May-June 1981 issue of Games magazine, with an acknowledgement to Morgan Worthy. Games ran several followups in subsequent issues, and reported that people kept resubmitting the puzzle to them, sometimes as original work! Many people have now added to the list of equations. The 24 original ones are starred (*) below.
A few more comments are needed about the esthetics of this type of puzzle in addition to those of Morgan Worthy above. A good letter equation emphasizes the uniqueness of the number on the left-hand side of the equation, and is not merely one in a long series of equations. For example, the equation 79 = AN of G = Atomic Number of Gold is excluded from the following collection, along with equations involving atomic weights, levels on some scale, years in which well-known events occurred, powers of integers, etc. The left-hand side must be an exact integer, thus 18.5 = ME from the WT = Minutes Erased from the Watergate Tapes is excluded, along with fundamental constants, non-integral conversion factors between units of measure, well-known dimensions, etc. Also, the left hand side cannot be a concatenation of digits, such as 12 = BMS = Buckle My Shoe.
There are a couple of conventions that we recommend but that are not universally observed. If a number occurs on the right-hand side of the equation, it is spelled out (as in 1 = B in the HWT in the B = Bird in the Hand Worth Two in the Bush). Finally, unlike Worthy, we do not put periods after the initial letters and we do concatenate consecutive ones ("BLSB" not "B L S B").
