David Pingree Sr. (1795–1863) enjoyed such enormous success in shipping that he was labeled “The Merchant Prince of Salem” in his day. Pingree sensed the demise of seafaring Salem, and he pursued a second career as a land baron. He acquired extensive holdings in New Hampshire, including much of Mount Washington, and in Maine, where his fifth-, sixth-, and seventh-generation heirs manage their timberlands via Bangor-based SEVEN ISLANDS LAND COMPANY.
