Gemma Galgani was born on March 12, 1878, in Camigliano, Italy, and later moved to Lucca with her family. From a young age, she exhibited deep piety and a profound devotion to the Passion of Christ. Despite suffering from various illnesses, including tuberculosis, Gemma maintained a life of intense prayer and was known for experiencing mystical phenomena, such as visions and the stigmata. She desired to join the Passionist nuns but was unable due to her health. Gemma passed away on April 11, 1903, at the age of 25.

The Church recognized Gemma's virtuous life by beatifying her on May 14, 1933, under Pope Pius XI, and later canonizing her on May 2, 1940, by Pope Pius XII. Her relics are enshrined at the Passionist Monastery in Lucca, Italy.

Gemma is venerated as the patron saint of students, pharmacists, and those suffering from various ailments, including back pain and headaches.

Pope Francis, reflecting on her life, stated, "Yesterday, we remembered Saint Gemma Galgani, apostle of Jesus’ Passion. Dear young people, live the Easter Triduum in her school, reflecting on the love of Jesus who immolated Himself for us on the cross."
