A U.S. Army second lieutenant was officially registered as an atomic bomb victim Monday at the Hiroshima National Peace Memorial Hall for Atomic Bomb Victims.

Joseph Dubinsky of Pennsylvania died at age 27 when the atomic bomb was dropped on Hiroshima, where he was being held as a prisoner of war, in August 1945. He is the eighth American POW to be registered at the hall.

A photo of Dubinsky was offered for the registration by his brother, who lives in Maryland and gave his consent, according to historian Shigeaki Mori.

Mori said Dubinsky was the pilot of a B-24 bomber on a mission to attack Imperial Japanese Navy vessels anchored off Kure, Hiroshima Prefecture, on July 28, 1945. His plane was shot down, he bailed out and was taken prisoner.

According to Mori's research, 12 U.S. service members died in the atomic bombing while being held as POWs. He added that he hopes to be able to register the remaining four by the 60th anniversary of the bombing next year.
