Walling Map of Lennox & Addington County
Henry Francis Walling (June 11, 1825 – April 8, 1889) was an American civil engineer, cartographer, surveyor, and map publisher active from the middle to late 19th century. Walling was born in Providence, Rhode Island. Walling established himself independently around 1850 and immediately began preparing a series of town plans. Apparently Walling’s business model involved a contract with town officials to produce a certain number of maps after which he acquired the right to print and sell additional copies on his own account.
