She was a nurse to General Giuseppe Garibaldi's soldiers in four wars; she researched living conditions in subterranean Naples and working conditions in Sicily’s sulphur mines. She wrote copiously (in English and Italian) as both a journalist and a biographer. Litta Visconti Arese in his introduction to The Birth of Modern Italy, says Jessie was the first woman journalist in England.
Her most famous biography was about Giuseppe Garibaldi.
