Emmett Grogan (c. 1943 - 1978) was a founder of the Diggers in the Haight-Ashbury district of San Francisco, California, USA who inspired Abbie Hoffman to undertake a similar venture on the Lower East Side of New York City during the mid-1960s. The Diggers were a hippie group that scrounged for and provided food and other services. They took their name from the Diggers of 17th Century England who were a radical movement opposed to feudalism, the Church of England and the British Crown. The Diggers of the 1960s can be compared with the present-day Food Not Bombs who feed homeless youth.
