when was bulimia first recognised as an eating disorder
Bulimia nervosa Globally, bulimia was estimated to affect 3.6 million people in 2015.[8] About 1% of young women have bulimia at a given point in time and about 2% to 3% of women have the condition at some point in their lives.[3] The condition is less common in the developing world.[4] Bulimia is about nine times more likely to occur in women than men.[5] Among women, rates are highest in young adults.[5] Bulimia was named and first described by the British psychiatrist Gerald Russell in 1979.[9][10]
Germ theory of disease Microorganisms are said to have been first directly observed in the 1670s by Anton van Leeuwenhoek, an early pioneer in microbiology. Yet Athanasius Kircher may have done so prior. When Rome was struck by the bubonic plague in 1656, Kircher spent days on end caring for the sick. Searching for a cure, Kircher observed microorganisms under the microscope and invented the germ theory of disease, which he outlined in his Scrutinium pestis physico-medicum (Rome 1658).[16] Building on Leeuwenhoek's work, physician Nicolas Andry argued in 1700 that microorganisms he called "worms" were responsible for smallpox and other diseases.[17]
