International Hygiene Exhibition
The International Hygiene Exhibition was a world's fair focusing on medicine and public health, held in Dresden, Germany, in 1911. The leading figure organizing the exhibition was German philanthropist and businessman , who had grown wealthy from his Odol mouthwash brand, and was enthusiastic to educate the public about advances in public health. Lingner had previously organized a public-health exhibition as part of the 1903 Dresden municipal expo, and its success led him to plan a larger endeavor. The exhibition opened on May 6, 1911, with 30 countries participating, 100 buildings built for the event, and  5 million visitors over its duration. It emphasized accessible visual representations of the body, and a particular sensation were the transparent organs preserved and displayed according to a method devised by Werner Spalteholz. Following the exhibition, its contents became the permanent German Hygiene Museum in Dresden. Its success spawned several follow-up expos, most notably the 1926 "GeSoLei" exhibition in Düsseldorf.
