To coincide with Fire Prevention Week, Morris County Historical Society (MCHS) at Acorn Hall will officially open its new exhibit, “Up in Smoke: Northern New Jersey’s Worst Man-Made Disasters: 1910-1989,” at Acorn Hall, Thursday, Oct. 10, 6 p.m. to 8 p.m. This photo-driven exhibit brings heroes to light, recognizes the sacrifices of those lost and illustrates the varied events that brought communities together, tightened safety regulations, and changed legislation nationally. Up in Smoke covers twelve 20th century disasters, five from Morris and seven from its contiguous counties that, due to their scale, severity, loss of life, or ability to cause major changes in workplace safety or fire science, stand as benchmarks with ominous connotations. Still, in understanding the severity of the situations, heroes, some as martyrs, emerge answering a call beyond requirements of duty and advancing our common cause. On Thursday, Oct. 10, at 6 p.m., Jeffrey S. Paul, director of the Office of Emergency Management, will be on hand to shed some insight into what drives some among us into such a dangerous service, often risking their lives for people they’ve never met. “Up in Smoke” will be available from Oct. 6, 2019, through April 26, 2020. Admission, which includes the exhibits and landscaped grounds, is $6 for adults, $5 for seniors, $3 for students and is free for children under 12 and MCHS members.
