Giovanni Battista de' Rossi was an 18th-century Italian priest known for his extensive charitable work in Rome. Born in Voltaggio in 1698, he overcame the challenges of epilepsy to serve the community, eventually becoming a canon at Santa Maria in Cosmedin. He dedicated his life to assisting the sick, prisoners, and homeless women, even establishing a hospice for the latter. Despite his health struggles, he became a highly regarded confessor after receiving special papal dispensations. He died in Rome in 1764 and was later canonized by the Catholic Church.
