A ceremony Wednesday in Naka Ward, Hiroshima, marked the opening of one of the houses built by U.S. peace activist Dr. Floyd Schmoe for people left homeless by the U.S. atomic bombing of the city.

Schmoe, who died in 2001 at age 105, built 21 homes and assembly facilities called "Houses for Hiroshima" between 1949 and 1953, financed by charity funds from the United States. Funds were also given to Nagasaki, where city housing was built.

The only such home in Hiroshima still standing will open Thursday as an exhibition facility attached to Hiroshima Peace Memorial Museum for remembering the atomic bombing.

Among about 80 people at the ceremony were Wilfred Schmoe, the 85-year-old son of the peace activist, and Hiroshima Mayor Kazumi Matsui.
