Some History Of I, J, And K

I learned a little bit of geek history today.  A lot of us have used the variable I (or i rather) in our loops, and sometimes for nested loops we would use j and then k.  Do you know where that started?

Apparently it started in FORTRAN.  The variables i, j, and k were to be only used for integer type variables.  I am sure there is more to it than that but a quick search gave two different sources that confirm it.

Wikipedia

StackOverflow

I know this is nothing ground breaking or anything, I just thought it was something neat.
