Caution, high voltage! Electrical accidents – a class of their own

In 1882 an engineer died in Austria's first known fatal electrical accident, and nobody tried to revive him: no one believed it was possible. The Viennese internist Stefan Jellinek spent decades proving otherwise, and the enamel sign from his Electropathological Museum, nicknamed the "Stromtotenmuseum", now hangs in the Narrenturm.

Three rooms hold specimens from his collection, which came here after that museum closed in 2002, with case histories and wall drawings of people caught by red lines of current. You finish on prevention, including the FI circuit breaker that physicist Gottfried Biegelmeier helped develop, partly by testing currents on himself. The curators say they avoided shock effects, though Der Standard notes some explicit displays.

Entry is €8, free for under-19s, or €22 combined with the main NHM. It is open Wednesday to Saturday, 10:00 to 17:00, at Spitalgasse 2 on the old hospital campus. Photography isn't allowed.
