Edgar Prosper, Smyrna, TN

Letter Carrier Edgar Prosper was delivering mail on a July day in Smyrna, TN, when he noticed a lawn mower running in a customer’s yard.

At first, no one appeared to be around, but upon closer examination, Prosper spotted the customer collapsed nearby.

The Postal Service employee rushed to check on the man, who was experiencing a diabetic seizure complicated by heat exposure.

Prosper alerted a neighbor, who called 911, and stayed with the customer until emergency responders arrived and took him to a hospital.

“Edgar is a Marine Corps veteran, an outstanding employee and a selfless person,” said local Postmaster Rodney Masengale.

Employees featured in “Heroes’ Corner” also receive letters of commendation through the Postmaster General Heroes’ Program. The nomination form is available on Blue.
