Operay Surgical Lights
About fifty years after the use of surgical amphitheaters such as the Ether Dome in Boston, Massachusetts; Scanlan Morris which later became Ohio Chemical and Manufacturing Company of Madison, Wisconsin produced the Operay Multibeam, a shadowless surgical lighting fixture during the first part of the 20th century. Ohio’s customers were primarily sanatoriums with surgical infirmaries. It was during this era that hospitals were also known as sanatoriums (also spelled sanitorium and sanitarium) have different meanings depending on the region of residence. Historically for Americans and most European countries it is a medical facility for long-term illness, most typically associated with treatment of tuberculosis (TB) before antibiotics. A distinction is sometimes made between “sanitarium” (a kind of health resort) and “sanatorium” (a hospital).
