Georg Theodor August Gaffky

Georg Theodor August Gaffky (17 February 1850 – 23 September 1918) was a Hanover-born bacteriologist best known for identifying bacillus salmonella typhi as the cause of typhoid disease in 1884.

His medical studies at the Friedrich Wilhelm University in Berlin were completed in 1873 after an interruption by the Franco-Prussian War in 1870.

Under Koch's leadership, Gaffky and others developed bacteriological protocols and achieved progress in identifying causes of infectious diseases.

In 1884, Gaffky published results reporting that he had isolated the eberthella or Gaffky-Eberth bacillus in 26 of 28 cases of typhoid.

[1] Gaffky was later part of an expedition to Egypt in which Koch identified transmission methods of cholera.
