Ben Franklin Installed New Hampshire Lightning Rod in 1763



J Dennis Robinson meets Ben Franklin



Franklin in Portsmouth


But did Ben Franklin actually visit Portsmouth, New Hampshire? The historical record says--yes. Local accounts place him here in 1763.  At the time, a dozen years before the American Revolution, Franklin was appointed Deputy Postmaster General to the colonies. For five months he traveled from New Jersey and New York to New England, inspecting and setting up post offices and improving delivery. 

Portsmouth was the northernmost stop on his tour. He arrived here some time between August 12 and September 5. Earlier in his tour, Franklin had fallen from his coach and dislocated his shoulder. He fell again in Portsmouth. and his recuperation delayed the journey. Rerunning to friends and family in Boston, he didn't get back home to Philadelphia until early November.

John Warner, a wealthy seaport merchant, was then owner of a fine brick mansion on Daniel Street near the Piscataqua River. Warner had married Mary Macpheadris. A widow and heiress, Mary's father had built the fortress-like brick structure in 1716. Warner was a member of the King's Council, and it is reasonable to assume that he met and entertained Franklin when the Deputy Postmaster for King George III visited Portsmouth, then a Royalist stronghold.  

Franklin's letters do not specifically mention Warner or anyone else in town, or even the dates of his Portsmouth visit. But we know that this gregarious man often stayed with key people during his five-month journey. Franklin happily accepted their luxurious accommodations. Local historians have conjectured that, having hurt himself traveling from Boston to Portsmouth, perhaps Franklin convalesced here in town and consulted with Warner about lightning rods.  


It is only a theory, based on Warner family lore, and there are skeptics. No documentation of Franklin's stay in Portsmouth has surfaced. Historian Phillip Dray does not mention Portsmouth in his book, Stealing God's Thunder: Benjamin Franklin's Lightning Rod and the Invention of America (2005).  A Boston newspaper, hearing about the Warner House lightning rod in 1873, found the claim dubious. "The next thing we shall hear," the newspaper taunted, "will be that Washington was a book agent and Thomas Jefferson a stove polish seller."

Electrifying evidence


Now dwarfed by the Connie Bean luxury apartments across the street, the Warner House would have been a skyscraper by 1716 standards. The earliest, urban brick house in northern New England served temporarily as the governor's mansion when royal Gov. Benning Wentworth and his family moved there in 1741. It was still a prominent site in 1763. Two years after Franklin's visit, a Portsmouth mob would take to the streets in protest of the hated Stamp Act.  


Experts agree that the crude lightning rod, still attached to the west side of the historic Warner House, matches the age and style of Franklin's early devices. Years ago the rusty slice of metal that grounded the lightning rod was removed by archaeologists. Half of the grounding rod had rusted away, but the remaining chunk is consistent with a pre-Revolutionary installation.



After studying the colonial fire prevention device, archaeologist Rick Morris, found the evidence convincing. The wrought iron grounding rod and two chain links led to a clay pit seven feet from the house foundation. This system, Morris concluded in a 1996 report,  was designed to Franklin's specifications.


Visitors to the museum (it re-opens for its 300th anniversary in June) can view the surviving L-shaped scrap of metal. The crude, hand-forged artifact rests in a glass case in a closet-sized space inside the grand wood-paneled mansion. It is a humble exhibit at best. A few faded sheets of paper  tacked to the wall tell the story of Franklin's game-changing invention.



Preserving a painting


This story sparks a newsworthy footnote. A commercial artist named Harry Harlow (1882-1963) first saw Portsmouth during World War I. He moved here in 1927. Captivated by colonial Portsmouth, he produced 50 small paintings of doorways in the city. Historian Dorothy Vaughan called Harlow "the kindest gentlest man you'd ever know."



In 1937 Harlow painted a life-sized portrait of Benjamin Franklin, replete with his lightning rod, standing in front of the Warner House. According to Warner House historian Ronan Donohoe, Harlow's picture hung for years in the original New Franklin School off Dennett Street, until that building was destroyed by fire in the early 1980s. Though severely damaged by smoke and water, the painting survived and was kept in storage by the Portsmouth School Department.


In 2011 the Portsmouth Historical Society offered to raise an estimated $2,000 to $3,000 to restore Harlow's lightning rod painting. The plan was to make the painting accessible to the public at the newly created Discover Portsmouth Center. In exchange for saving the painting, the historical society would become owners of the forgotten work or art. 



Ed McDonough, then Superintendent of Schools, presented the idea to the Portsmouth School Board. But, unwilling to give up ownership of the painting, the board turned the museum's offer. School Board member Kent LaPage was quoted as saying, "I understand someone wanting to take ownership, but I could never support that."


"I thought I was doing a good thing, but it didn't work out," Ed McDonough says today from his office in Freeport, Maine, where he is currently school superintendent. "So we just kept it."


Once stored behind the office door of the secretary to the superintendent, the deteriorating Benjamin Franklin portrait has found its way into storage in the basement of Little Harbor School.

When asked how a damaged historical painting stored in a school basement contributes to the education of Portsmouth students, current School Superintendent Stephen Zadravec says, "That's a good question."


"There certainly is interest in restoring it," Zadravec says, with an eye to the city's looming 400th anniversary in 2023. "Perhaps this would be a good time to revisit that decision."
