On Jan. 16, 1943, Dallas Groce, 43, died in an explosion and fire at the Crowell-Collier Publishing Co. plant.
The blast occurred just before noon in the penthouse atop the sixth-floor of the plant west of downtown Springfield, Fire Chief Grover Frock said.
Other workers sustained injuries, according to an Associated Press story printed in the Youngstown Vindicator.
Chief Frock blamed the explosion on spontaneous combustion.
It caused $25,000 in damages.
