Johannes Flintrop

Johannes Flintrop (May 23, 1904 – August 28, 1943) was a prominent Roman Catholic critic of the Nazi Party who died in the Dachau concentration camp.

Flintrop was born in Barmen (Wuppertal) to devout working class parents.

After his theological studies at the University of Münster, he was ordained a Pastor in Cologne in 1927.

In 1941, he admitted to youth of the Catholic Kolping workers society that the war had long not been won, and that "it is likely that we (German troops) too committed war atrocities" in the Soviet Union.

Surviving inmates of the concentration camp reported that he was forcefully subjected to medical experiments and died as a result of them.
