Piotr Gontarczyk (born April 29, 1970 in Żyrardów) is a Polish historian with a doctorate in history and political science.
Gontarczyk is employed by the Polish Institute of National Remembrance and specializes in history of the Polish communist movement during the World War II and in contemporary history. In 2008 Gontarczyk and Sławomir Cenckiewicz published a historical publication entitled "SB a Lech Wałęsa. Przyczynek do biografii" ("Lech Wałęsa & SB"). The book caused a major controversy in Poland and both authors were heavily criticised.[1] In their work Gontarczyk and Cenckiewicz claim that in the 1970s the Solidarity leader and former President of Poland Lech Wałęsa was a secret informer of the Polish communist secret police - Służba Bezpieczeństwa (SB).[2]
Gontarczyk's work as a historian, researcher and political scientist comprises several books and numerous press articles as well as scientific papers.
