On March 2, 1854, a steam boiler explosion rocked the Fales & Gray Railroad Car Works factory on Potter Street in Hartford. The explosion destroyed the blacksmith’s shop and engine room killing nine people immediately and seriously wounding fifty. Twelve people later died from their wounds. At the time of the blast, there were more than three hundred people employed in the building and the tragedy underscored the reality that Hartford needed a professional health care facility. In May of 1854, the State of Connecticut granted a charter for the formation of Hartford Hospital.
