| Author | Loeffler |
| Contribution | With Frosch, reported filterable germ (virus) as agent of animal disease. |
| Reference | Brock |
| Notes | They reported that the agent of bovine hoof-and-mouth disease could pass through bacteriological filters, and that it multiplied in cattle and so was not a chemical toxin. They assumed it was a submicroscopic bacterium, but were apparently the first to show that an animal disease was caused by what we now call a virus. Result of commission begun in 1897; findings published '97 and '98 (key finding in the '98 section?). Greer Williams, in "Virus Hunters," devotes several pages to Beijerinck but only one sentence to Loeffler and Frosch. See Brock 1961 for English translation. |
