Jack Greenberg, a Canadian national residing half of the year in Seoul and the other half in Yeongcheon, expresses his commitment to shedding light on the significant yet underreported massacres of Korean civilians post-World War II. In a meeting at a café in Seoul, he reveals his deep interest in the October Uprising, a mass civil uprising against the US military government that took place in the Daegu-Gyeongbuk region in 1946, and the subsequent National Safety League massacres where group executions were carried out on civilians by the military and police. Greenberg has become an invaluable source of knowledge on these historical events, connecting the past with present issues affecting South Korea.

Greenberg's journey into Korean history began during his teenage years in Toronto when he learned about the Korean Truth and Reconciliation Commission. This understanding deepened when he wrote his undergraduate thesis on the topic in Montreal. Now, he traverses key massacre sites in Korea, including the Ajagol site in Yeongcheon, the Goryeong-gol in Daejeon, and has broadened his interests to include overseas adoption and the atrocities committed by Korean forces during the Vietnam War. His work not only emphasizes the need for a comprehensive reckoning with Korea’s past but aims to contribute to the global discourse surrounding human rights and historical justice.

While many foreigners may take an interest in K-pop and other superficial aspects of Korean culture, Greenberg stands out for his profound engagement with Korea’s complex history of trauma and resilience. Currently working as an independent consultant, he helps international companies with projects related to Korea while also contributing articles about Korean historical issues to various news agencies. He advocates for the truth about events like the Baengnyeongjeong incident, indicating that there is still much work to be done to uncover the full scope of the injustices experienced by civilians during the turbulent periods of Korea's history.
