Botulinum toxin
In 1895 (seventy-five years later), Émile van Ermengem, professor of bacteriology and a student of Robert Koch, correctly described "Clostridium botulinum" as the bacterial source of the toxin. Thirty-four attendees at a funeral were poisoned by eating partially salted ham, an extract of which was found to cause botulism-like paralysis in laboratory animals. Van Ermengem isolated and grew the bacterium, and described its toxin, which was later purified by P Tessmer Snipe and Hermann Sommer.
Bodog F. Beck
Bodog Felix Beck (1871 – 1 January 1942) was a Hungarian-born American physician who specialized in the treatment of arthritic and rheumatoid conditions using bee venom and who coined the term "bee venom therapy". There are no studies proving the ability of bee venom to cure any ailment.
