Origin of the LIWC  

In the summer of 1956, USDA researchers and industry partners organized an informal meeting they called the "Animal Systemic Insecticide Conference" to disseminate information on pest control products for cattle.  In 1957, this meeting was expanded and renamed as the Livestock Insect Workers Conference with the first Annual Meeting held in Kerrville, TX. At the 61st Annual Meeting of the LIWC held in Savannah, GA, founding member Roger Drummond discussed the origin and early years of the LIWC which you can read be selecting the link below.
