Ryszard Feliks Piotrowski , born in Warsaw, was a Major in the Polish Armed Forces and a member of the Polish resistance / Home Army. He fought in the "Sowinski" Battalion, "Waligora" Grouping, under his wartime code name Piorun. Piotrowski took part in the Warsaw Uprising, the largest single military effort taken by any European resistance movement during World War II and the largest scale World War II operation by the Home Army to liberate Warsaw from Nazi Germany. The Uprising was timed to coincide with the Soviet Union's Red Army approaching the eastern suburbs of the city and the retreat of German forces. However, the Soviet advance purposefully stopped short, enabling the Germans to regroup and demolish the city while defeating the Polish resistance, which Piotrowski fought in for 63 days with little outside support. After a 63-day fight, Piotrowski was captured and sent to the first of 5 camps he would be imprisoned at; Lamsdorf, a German prisoner of war camp which housed Polish prisoners from the German September 1939 offensive. More than 100,000 prisoners from Australia, Belgium, Britain, Canada, France, Greece, New Zealand, the Netherlands, Poland, South Africa, the Soviet Union, Yugoslavia and the United States passed through this camp. He was later transferred to another German prisoner-of-war camp, Luckenwalde, located in Brandenburg, 52 kilometers south of Berlin. At its height in May 1944, a total of 48,600 POW's were registered there. Piotrowski was held there until the end of the war. After the war, he studied economics and became a professional economist with Inco-Veritas S.A., a privately-owned Polish chemical products consortium founded in 1947. A devout Christian, Piotrowski refused to join the newly formed communist party of Poland, the Polish United Workers' Party, making life even harder than it was for Poles at the time. As a result of his refusal to join the party, nearly all of the Piotrowski family's land, real estate and bank account holdings were confiscated and never returned by the government, at the time a satellite state of the Soviet Union. On 25 August 1948, Piotrowski married Teodora "Tonia" Starostka. They had three children, Nina, Wanda and Aleksandra. Wanda died 17 days after being born. After 33 years of marriage, Tonia died on October 13, 1981 at the age of 56 from breast cancer. Among the many orders, decorations and medals of Poland received by Piotrowski, in 2011, he was awarded the Order of Polonia Restituta, one of Poland's two highest decorations, awarded only to the most distinguished Poles and the highest-ranking representatives of foreign countries. On June 2, 2016, Piotrowski died of complications from Alzheimer's disease.
