In the Tamaqua area, coal mining was a vital economic activity throughout the 20th century but with the diminished use of coal as a power plant fuel and the demise of steam powered traction, has since experienced a decline. The town also gained recognition as a railroad center. In addition, the 1885 Edison Electric Illuminating Co. of Tamaqua is said to have furnished the town with the nation's second incandescent municipal lighting system, a feat accomplished through the involvement of Thomas Edison.
