The untold story of Boston’s Floating Hospital and the nurses whose work redefined infant care

In late nineteenth-century Boston, nearly one in five babies did not survive infancy. Each summer, outbreaks of “summer complaint”—a deadly gastrointestinal illness caused by contaminated cow’s milk—swept through the city’s poorest neighborhoods. Infants born to immigrant families were especially vulnerable, trapped in stifling tenements with poor sanitation and little access to safe nutrition. Searching for a solution, reform-minded Bostonians looked to New York City’s hospital boats, which offered sick children relief from the heat. In the summer of 1894, Boston launched its own bold experiment: the Boston Floating Hospital.

What began as a modest charitable venture in Boston Harbor soon transformed pediatric care. While physicians have long received credit for the Floating Hospital’s success in reducing infant mortality, Harbor of Hope tells a deeper story. Historian Arlene W. Keeling reveals the essential and often overlooked role of nurses. It was nurses who translated medical theory into lifesaving practice: feeding and bathing fragile infants, administering treatments, calming anxious mothers, and carefully observing each child’s response. Serving as the vital link between doctors and families, they became the heart of the Floating Hospital’s mission.

Tracing the hospital’s story from its first voyage to its tragic destruction by fire in 1927, Harbor of Hope situates these nurses within a city undergoing dramatic change. Against the backdrop of rapid industrial growth, mass immigration, and emerging movements in public health and social reform, Keeling shows how skill, compassion, and persistence reshaped the fate of Boston’s most vulnerable children. Set afloat on Boston Harbor, this is a powerful story of caregiving, innovation, and the women who fought day after day to save babies’ lives.
