Robert Moon
Robert Moon (
1917-
2001), sometimes called 'Mr. Zip' is considered the father of the
zip code or zoning improvement program, a mechanism to route mail. He developed the idea in the
1940s while working as a Postal Inspector in
Philadelphia, but the Directory of Post Offices, using zip code numbers, was not delivered until
1963. He lived in Philadelphia,
Chicago,
Reston, Virginia, and
Leesburg, Florida.
