LZ means "Landing Zone"

LZ Granderson was born on 1972-03-11.

Already answered this question, but didn't define the "LZ" part. LZ=Landing Zone.

During the Vietnam War, LZ stood for Landing Zone. Within weeks or months many of those Landing Zones became firebases. Consequently, one might hear the words, "LZ Blackhawk or LZ Rifle"...when referring to Firebase Blackhawk or Firebase Rifle.

The LZ's were for designated helicopter landings originally.
