Cambridge is a city in Dorchester County, Maryland, United States. The population was 12,326 at the 2010 census. It is the county seat of Dorchester County and the county's largest municipality. Cambridge is the fourth most populous city in Maryland's Eastern Shore region, after Salisbury, Elkton and Easton. Cambridge developed food processing industries in the late 19th century, canning oysters, tomatoes and sweet potatoes. Industrial growth in Cambridge was led by the Phillips Packing Company, which eventually grew to become the area's largest employer. The company won contracts with the Department of Defense during the First and Second World wars that aided its growth. At its peak, it employed as many as 10,000 workers. Changing tastes brought about a decline in business leading Phillips to downsize its operations. By the early 1960s the company ceased operations altogether. This led to widescale unemployment and added to the city's growing social problems.
