The National Watch & Clock Museum has extended its special exhibit "S-Town Exquisite Clocks" to run three more months due to continued public interest. Home to a large collection of clocks, watches, and horological artifacts, the National Watch & Clock Museum is exhibiting examples that showcase the talent of John B. McLemore, the focus of the acclaimed podcast "S-Town" from the makers of "Serial" and "This American Life." The exhibit will be on display through Wednesday, July 31.

More than just the inspiration for the "S-Town" podcast - which attracted millions of listeners when it broadcast in 2017 - McLemore was a highly accomplished clockmaker who restored fine clocks. He was particular about the way that he worked and carefully replicated historical methods to ensure the accuracy of his work.

His commitment to that accuracy may well have cost McLemore his life, as he used fire-gilding to apply gold to his clocks. The old method produces good results, but it relies on melting mercury with gold and produces extremely toxic mercury vapors.

The National Watch & Clock Museum houses approximately 13,000 timepieces. The museum is run by the nonprofit National Association of Watch & Clock Collectors Inc., whose nearly 10,000 members come from the U.S. and other countries around the world.

The museum is located at 514 Poplar St., Columbia, and is open to the public on Tuesdays through Saturdays from 10 a.m. to 5 p.m. For more information, visit http://www.museum.nawcc.org or call 717-684-8261.
