3. The Bath School Disaster (1927)
Long before school safety became a national issue, the Bath School Disaster shocked the nation. In 1927, a disgruntled school board member in Bath Township, Michigan, planted explosives in the local school. The resulting blasts killed 45 people—most of them children—and injured dozens more. The tragedy devastated the small community and remains the deadliest school massacre in U.S. history. Despite its horror, this event is rarely discussed in classrooms today.
