Mercer Museum & Fonthill Castle

From the Renaissance to global warming today, scientists have developed ingenious ways to record the changing skies. While Torricelli’s barometer has endured, other instruments have not, like the leech-based electrical “tempest prognosticator” built in 1851 by the appropriately-named George Merryweather. But history shows the secret to measuring weather ultimately lies in combining instruments with innovative social organizations managed by government bureaucrats.

Join us for a Zoom presentation with Roger Turner, museum curator at the Science History Institute in Philadelphia, as we explore this fascinating topic. Turner also runs, a blog for compelling stories about the people who study weather.
