A factory for manufacturing Prest-o-Lite (used to make the first true car headlights by compressing acetylene gas into canisters) was built to the south of the second St. Vincent Infirmary location in the early 1900s. In 1908 alone, this volatile process caused explosions and fires three times, the third one severely damaging the infirmary. This danger, along with dirt and noise from the railroad tracks and train sheds and to the north, were among the reasons for relocating St. Vincent's to Fall Creek Boulevard in 1913.
