Paul Geidel retired from the FDNY in 1976 after twenty years of service. His three sons followed in his footsteps and all became firefighters.
On September 11, Paul's son Gary perished with the rest of his unit, his father's old unit, Rescue 1.
Paul immediately returned to service and, joined by his other sons Ralph and Michael, spent the next nine months searching for Gary's remains and those of everyone else who died in the attack.
No trace of Gary has been found to date.
