U.S. theatre gas-lights

In 1816, the Chestnut Street Theatre at Philadelphia, Pennsylvania, was illuminated with gas lights. Impressed with Dr. Charles Kugler's demonstration at Peale's Museum of lights "burning without wick or oil," the managers, Warren and Wood, had Kugler install a plant to generate gas at their theatre. Although the managers announced that audiences could expect their gas lights gave "superior safety, brilliance and neatness," there was some considerable opposition from some quarters. The works were denounced as a menace to public health and safety, emitting an unpleasant stench, with a potential for an explosion causing death and destruction*.
