Hwangbo Su-Ja , board member of the Association of Korean Miners

This picture taken on December 31, 2013 shows Hwangbo Su-Ja , board member of the Association of Korean Miners and Nurses Dispatched to Germany, pointing to a picture which was taken of her and her colleagues while she worked in Germany, in the Memorial House of Miners and Nurses Dispatched to Germany in Seoul. She was one of the nurses dispatched to Germany in 1966 for 3 years. Fifty years ago, several hundred South Koreans went to work in German mines -- the first wave of a flood of Korean migrants whose remittances helped jumpstart one of the great economic transformations of the modern age.
