The Great Salem fire of June 25, 1914, destroyed 1,376 buildings and made over 18,000 people homeless or jobless in Salem, Massachusetts, U.S.
It was among the last of the great industrial fires that plagued North American cities in the 19th century. Of the families it affected – burning homes or the breadwinner's workplace – 43% were Franco-American. Because so many people were left jobless after the city's largest employer burned down, the fire encouraged the creation of the United States Employment Service.
Franklin H. Wentworth agitated for more fire protection. In an article in the Salem Evening News (March 29, 1910, page 7), he called Salem, "in Danger of Destruction by Fire". He felt that the main fire danger was to the downtown business district. The article included a map of all downtown buildings and their type of materials.
Mr. Wentworth, a Salem Councilman, introduced an order that would have required all new or replacement roof coverings to be non-combustible. He argued that this was as important as buying new engines or hiring new firemen. After a big fire, many of the working class would have to live in tents, he warned.
Wentworth was accused of serving only the interest of the insurance industry, and the amendment did not pass. Wentworth later became secretary of the National Board of Fire Underwriters.
Another failed attempt to increase safety in Salem was undertaken by Charles J. Collins. He had visited Philadelphia where high-pressure wagons pumped water through 3.25 inches (8.3 cm) pipes for a range of 360 feet (110 m). The argument went that high-pressure pumps would pay for themselves with the reduction of insurance fees. Protecting the entire business and mercantile district would have costed US$150,000.
In 1914, Salem was a city of 48,000 people (12,000 more than ten years earlier), and consisted of 5,826 buildings on 5,100 acres (21 km2; 8.0 sq mi) at an assessed valuation of US$37.25 million. The streets were 20 to 140 feet (6.1 to 42.7 m) wide, and building codes were dated and did not mention standpipes, fire escapes, or sprinklers.
