Florence Nightingale was a pioneering nurse and social reformer who revolutionized healthcare during the 19th century. She played a crucial role in professionalizing nursing, emphasizing hygiene, patient care, and data-driven medical practices. Her feminist impact lies in how she challenged societal norms by entering a male-dominated field, advocating for women’s education in medicine, and proving that women could lead in science and public health. Nightingale’s legacy paved the way for women in healthcare and inspired future generations to challenge gender-based limitations in professional fields.
