I just Ctrl+F'd "Gleason" in The Art of Computer Programming Vol 1, Vol 2, Vol 3, Vol 4A, and Vol 4B, with no hits in any of the 5 books.

I even looked in the glossaries. There's lots of last names -- Glaisher, Glassey, Gnedenko -- and no "Gleason".

I'm tempted to side with this iteration of CyberD's brutal takedowns on this one. :D

---- EDIT ----

WAIT: I found it in the glossary of Vol 3!

"Gleason, Andrew Mattei, 193, 648."

For this one, case sensitivity got me when I searched "gleason"!

The most relevant bit here seems to be page 193, discussing ways to minimize the average number of comparisons:

```

The minimum possible average number of comparisons, obtained by dividing by N, is never less than lg N and never more than lg N + 0.0861. [This result was first obtained by A. Gleason in an internal IBM memorandum (1956).]

```

"Gleason" is only mentioned in Vol 3.

"Gleason bound" is not used in Vol 3, which must be why it doesn't pop up on Google.

That's great that you found actual information, but that doesn't seem to back up this person's bizarre claims that 'nothing beats heapsort'.
