Hanna (Hannah) Helena (Helen) Chrzanowska (7 October 1902 – 29 April 1973) was a Polish Roman Catholic who served as a nurse and was also a Benedictine oblate.

Chrzanowska worked as a nurse during World War II when the Nazi regime targeted Poles, but she tended to the wounded and the ailing throughout the conflict and sought to minimize suffering in her own parish.

Pope Francis declared her to be venerable on 30 September 2015 upon the confirmation of her heroic virtue and later approved her beatification in mid-2017; Chrzanowska was beatified on 28 April 2018 in Poland.

[2] Hanna Helena Chrzanowska was born on 7 October 1902 in Warsaw to Ignacy Chrzanowski (5 February 1866 – 19 January 1940) and Wanda Szlenkier.

[3] Since her childhood she suffered from respiratory and immune system deficiencies and spent a great deal of time in hospitals and sanatoriums in order to recover from such ailments.

Before she was admitted into nursing school she volunteered at a clinic for six months but was assigned bookkeeping duties that did not appeal to her for she wanted to be with people.

[2][1] Chrzanowska also traveled to Belgium to observe the nursing profession there as part of her education so as to gain greater experience and broader knowledge of the field.

During her time as a nurse, she became a leading light in the field in her region and became a well-known face in her local area due to her temperance and her good works amongst the people whom she was dedicated to serving.

In 1940 during World War II she lost her father who died during the Sonderaktion Krakau at the Sachsenhausen concentration camp and her lieutenant brother Bogden, an officer in the Polish Reserves, was murdered by the Soviets in Katyn.

Chrzanowska succumbed to the disease on 29 April 1973 in her apartment at 4:00 am and the cardinal archbishop of Kraków Karol Józef Wojtyła – the future Pope John Paul II – celebrated her funeral.

The Positio was presented to Rome for further evaluation in 2011 and Pope Francis recognized that she had lived a life of heroic virtue thus proclaimed her to be Venerable on 30 September 2015.
