Hang. Scrub that last bit. I've just consulted the Urban Dictionary and it says the following on the term hooker.

"prostitute. started in the civil war When Gen.Hooker of the Union Army (the first pimp) tried to protect his troops from VD by buying the best chicks and pimping them to his corps of 20,000 men. orginally hooker's girls."

Sounds like a rather enterprising chap.
