Veteran TV and radio journalist David Tereshchuk (PBS and NPR) reveals the central paradox of his life in his new memoir, A Question of Paternity: Life as an Unaffiliated Reporter. Born David Brown in the U.K., Tereshchuk has traveled to the world's most war-torn regions - from Northern Ireland to Southern Africa to Bangladesh - asking tough questions and uncovering hard truths. Yet, he has never uncovered the answer to one personal mystery: who was his father?

To launch the book at the American Irish Historical Society, Tereshchuk will be in conversation with renowned Irish activist and journalist Don Mullan, author of Eyewitness Bloody Sunday. Mullan’s work is officially credited as a primary catalyst for the establishment of the new Bloody Sunday Inquiry, which became the longest-running and most expensive in British legal history, ultimately leading to the historic Bloody Sunday apology by Prime Minister David Cameron.

Both men were eyewitnesses and survivors of the brutal killings in Derry on January 30, 1972. Now, they come together again to re-examine that traumatic episode and discuss how it shaped Tereshchuk’s long career focused on global conflicts - all while he sought to discover the identity of his father.
