Gidon Barry was born in California on October 30, 1961 to Edward and Patricia. In October 1979 he first visited Israel and spent six months on Kibbutz Gazit, after which he became an oleh, and was 'adopted' by a kibbutz family.
In August 1981 he was drafted into the army. The First Lebanon War (Shlom Hagalil) prevented him from going on a trip to the US, and instead he joined his unit in Lebanon.
On June 11, 1982 while fighting in the central region, near Ein Zahalta, he went to rescue a tank crew, caught in a Syrian ambush, and was killed by Syrian fire. He was buried in the cemetery at Kibbutz Gazit.
