1876. Victoria Brú Sánchez is born in the Managua area, in Havana.

From a very young age she felt a vocation for nursing, hence she assisted sick relatives and friends. On January 21, 1910, she is appointed Superintendent of the "Number One" Hospital and of her Nursing School, where she works for 4 years. On March 14, 1914, she is transferred to the Cienfuegos hospital, with the same responsibility. She was performing these functions when, in 1918, a terrible influenza epidemic broke out. When this disease began to wreak havoc among the population, she was on leave due to health problems. The hospital was full of patients, the work was excessive. In the poor neighborhoods of the city the disease made more victims and its effects were more serious. Incorporated into her work, she was a victim of the epidemic itself that confined her to bed for several days. With her death on December 7, 1918, she thus became a martyr of the humanitarian profession she had chosen, following her firm vocation.

In Cuba, Nurses' Day was commemorated for the first time on June 3, 1924 as a tribute and remembrance of the nurse Victoria Brú Sánchezbirth had taken place on April 3, 1928 in Havana.
