Word people like finding out stuff, so they search - as the many exhortations to google here attest - and so we frequently employ Boolean operators . And so, the inquisitive person that I am, with an interest in biogs, googled... and came up with this:

""Boolean" honors George Boole, a 19th-century British mathematician who suggested that logical thought could be expressed as algebra. As you'll see below, it seems logical."
and this:
"Yes, George Boole (1815-1864) was an English mathematician who helped establish a field of mathematical study called symbolic logic. This system, known as Boolean logic, is basic to the design of digital computer circuits. It also is the basis for computer database searches. Bacause many Internet search engines are based on Boolean logic, so it is important to understand how this system works."

So I thought I'd share it so we could all be thankful together.
