Abstract
The Natural History Museum London houses one of the largest and most historic earthworm collections in the world. Despite some periods of inactivity, largely due to international events and a lack of general enthusiasm by collectors worldwide in some eras, it has continued to grow. Periods of rapid expansion of the collection coincide with eras of resident Oligochaete researchers at the Museum, however, the general growth can be in part attributed to Oligochaetoligists world wide and the assistance they provided each other and their respective institutions, something they continue to do to this day. This paper highlights the periods of growth, explains the times of inactivity and highlights the collection for future depositions and further utilisation by researchers worldwide.
