Bath, Michigan: The School Treasurer Who Spent Eight Months Planting Dynamite

In May 1927, the small farming community of Bath Township, Michigan, suffered the deadliest school attack in American history, and nearly a century later most Americans have never heard of it. Andrew Kehoe, a 55-year-old trained electrician and school board treasurer, spent eight months secretly wiring Bath Consolidated School with more than a thousand pounds of dynamite and military-surplus pyrotol. On May 18, 1927, he detonated the north wing at 8:45 AM, killing 38 children and 6 adults. The south wing charges never went off because of a faulty alarm clock mechanism, which spared 106 students sitting directly above 500 pounds of live explosives.

Kehoe also murdered his wife Nellie, destroyed his own farm with incendiary devices, and set off a truck bomb near the rescuers, killing Superintendent Emory Huyck, postmaster Cleo Clayton, and resident Glenn Smith. The community of Bath chose to rebuild the school on the same site. Among the families who returned was that of eight-year-old survivor Bernice Sterling, who had lost three siblings that morning.

Historical Significance

The Bath School disaster remains the deadliest school attack in American history, worse than every incident that has followed it. Michigan wrote the first school building safety codes in direct response, covering basement security, access restrictions, and background checks for staff with building access. In 1994, at age 75, survivor Bernice Sterling testified before Congress about school safety. The Bath School Memorial Museum, established in 1975, preserves evidence including the original clock stopped at 8:45 AM. The community's cup and saucer tree, built with dishes salvaged from victims' homes, still stands as a place people travel to see. The last survivor died in 2018 at age 99.
