He was razor-keen, alert, and a good Liverpudlian to have on your side. He was a shiny black Alsatian named Jet of Iada, and his search training freed 150 Londoners from the rubble of the Blitz in WWII. If you were still alive, he would give his all to find you.
This page from the Liverpool Museums tells you a bit more about this little-known four-legged war hero, who won a Dickin Medal for his rescues and rests now in a nice park in his home town of Liverpool. As his owner's daughter recalls it, "My mother (kennel owner Mrs. Babcock Cleaver) had been in touch with Liverpool City Council to ask what they could do? Whether the park would give him a site because Calderstones Park meant so much to her, and everything was set in motion. It was a very very satisfying day, sad, but satisfying, because he was a special person." (emphasis mine - Curator)
She speaks of a few more memories of this brave fellow, and you can read those here. Plus there is a treasure trove of information on Jet at this site,which is written by another Cleaver family member. Wonderful.
