Around 11,000 years ago, small groups of Native Americans camped around the area of what is now called Berlin. In later years, the Eastern Abenaki tribes came to Berlin to mine rhyolite on Mt. Jasper. When English settlers came here, Berlin was first granted on December 31, 1771 by Colonial Governor John Wentworth, as Maynesborough after Sir William Mayne, a West Indies trader. But the grantees did not take up their claims, which disappeared with the Revolution. Instead, Maynesborough was settled in 1823-1824 by William Sessions and his nephew, Cyrus Wheeler. Both men were from Gilead, Maine. Farming was the first industry. With 65 inhabitants in 1829, the New England town was reincorporated as Berlin with the help of Thomas Wheeler, the father of Cyrus.
