Book excerpt: Poet Walt Whitman proclaimed his adopted home of Camden, in its heyday, "the city invincible," a powerhouse of industrial might destined for greatness. Camden resurrects that fascinating era of invincibility through powerful images of the Benjamin Franklin Bridge construction; Cooper Hospital's nearly ill-fated founding; and the momentous birth of Campbell Soup Company, Victor Talking Machine Company/RCA, and New York Shipbuilding. Also included are images of Camden's neighborhoods, community life, and bustling downtown district, as well as the newsmakers and lawbreakers who defined the "biggest little city in the world."constants in our lives.
