John Friedrich Krasny (c. 1915 – 8 April 2005) was a Vienna-born Ritchie Boy (Class 10) interrogator with Fifth Armored Division who later researched textile flammability for NIST.

Biography edit

John Friedrich Krasny was born in Vienna and worked in his mother’s textile factory in Czechoslovakia before immigrating to the United States in 1938. He labored in North Carolina textile mills until entering the Army in September 1941 and training in intelligence at Camp Ritchie (Class 10).

Attached to the 5th Armored Division from D-Day through the end of the war, he interrogated German prisoners and civilians. Krasny later wrote that Ritchie Boy teams warned SHAEF of the German buildup before the Battle of the Bulge and felt those warnings went unheeded. He received the Bronze Star.

After the war he earned a physics degree at the University of Denver (1948) and a master’s in statistics at American University (1958), working on textile research for the National Bureau of Standards / NIST and Gillette. Author of more than eighty technical papers, he died of congestive heart failure on 8 April 2005 at Asbury Methodist Village in Gaithersburg, Maryland, at age 90.
