Professor Erwin Hamilton of New York University took over the Oak Island search from Gilbert Hedden in 1938, when Hedden ran into financial difficulties. Known locally as "Hammy," Hamilton was a rare figure in Oak Island history: a credentialed academic who believed the mystery warranted serious investigation and was willing to get his hands dirty proving it.
Hamilton drilled in the Money Pit area beginning in 1939 and found suspicious rocks and gravel at 190 feet - materials he believed had been deliberately placed. While his discoveries did not produce the breakthrough treasure hunters hoped for, his methodical approach lent the search a measure of academic respectability it had often lacked. He also corresponded with FDR, who wrote to him in 1938: "I wish much I could have gone up the coast this summer and visited Oak Island and seen the work you are doing - for I shall always be interested in that romantic spot."
Hamilton was forced to cease operations in 1943 due to World War II, but he never truly left Nova Scotia. He settled in the area and went into partnership with local boatbuilder Amos Nauss in Marriott's Cove, where the two designed and built wooden sailing craft together. Hamilton died before they could complete their final project - a 24-foot cedar hull that, unknowingly, anticipated the lines of what would become the classic Bluenose sloop design.
Captain Henry Livingston Bowdoin was a New York-based engineer and adventurer who founded the Old Gold Salvage and Wrecking Company in 1909. Incorporated in Arizona with $250,000 in shares at a dollar each, the venture attracted a roster of prominent investors - most notably a 27-year-old law clerk named Franklin Delano Roosevelt. Bowdoin claimed that "with modern methods and machinery, the recovery of that treasure is easy, ridiculously easy."
The expedition arrived on Oak Island in August 1909. Operating under a lease from Sophia Sellers and a treasure trove licence held by Frederick Blair, Bowdoin's team drilled multiple holes to depths of 155 to 171 feet, spaced so that anything over two feet square should have been struck. They found cement six to ten inches thick at depths of 146 to 149 feet, but laboratory analysis by Professor Chandler of Columbia University concluded it was natural limestone pitted by water action - not man-made concrete. By November 1909, the team packed up having found no treasure.
The aftermath proved more consequential than the dig. On August 19, 1911, Bowdoin published a detailed firsthand account in Collier's Magazine titled "Solving the Mystery of Oak Island," declaring there had never been any treasure. He also examined the famous inscribed stone at Creighton's bookbindery in Halifax, describing it as "basalt type, hard and fine-grained" with no visible symbols - though he was told they had worn off. Blair was furious, responding with a vigorous defence in the Amherst Daily News in February 1912, claiming Bowdoin had written the article in revenge after the two fell out. Bowdoin's scepticism made him the first significant voice to publicly challenge the treasure narrative, a stance that has only gained adherents in the century since.
James Pitblado was the drilling foreman of the Truro Company during their 1849 expedition to Oak Island. What he did during that summer created one of the enduring mysteries-within-the-mystery that still haunts the Oak Island story.
As the pod auger brought up material from deep in the Money Pit, multiple witnesses - including large shareholder John Gammell, whose "veracity could not be questioned" - saw Pitblado take something from the auger, wash it carefully, examine it closely, then slip it into his pocket. When challenged by his fellow crew members, Pitblado refused to reveal the object, saying he would present it at the next directors' meeting. He never appeared.
Instead, Pitblado left the island and, together with Charles Dickson Archibald of the Acadia Iron Works in Londonderry, obtained a treasure-hunting licence from the provincial government on August 6, 1849. The pair then attempted to purchase the eastern end of Oak Island where the Money Pit was located, but were refused by the owners. Archibald eventually retired to England; Pitblado vanished from the Oak Island record.
What did he pocket? Speculation has ranged from a gold nugget to a gemstone to a piece of worked metal. Archibald's expertise in metallurgy suggests the artifact may have been metallic. Despite the legend claiming Pitblado died shortly after in a railway accident, that was actually his brother John. James Pitblado lived to the age of 81, dying in July 1903, having never publicly revealed what he found. The secret, whatever it was, died with him.
Jotham Blanchard McCully (1819-1899) was an engineer from Truro, Nova Scotia, who served as manager and drilling engineer for the Truro Company from 1849, and later as secretary of the Oak Island Association in the 1860s. His involvement spanned roughly two decades of active treasure hunting, but his most lasting contribution was literary rather than archaeological.
In October 1862, McCully published "The Oak Island Diggings" in the Liverpool Transcript - a detailed response to a sceptical article entitled "The Oak Island Folly." This account was the first comprehensive written narrative of the Money Pit story, and it introduced elements that have defined the legend ever since: the three discoverers named as McGinnis, Smith, and Vaughan; the oak trees standing in triangular formation with letters carved into their bark; the inscribed stone at 80 feet described as "cut square, two feet long and about a foot thick, with several characters on it"; and the detailed layering of the pit itself. McCully also provided the verbatim drilling account that described the auger passing through layers of spruce, oak, and "metal in pieces" - the famous description of what appeared to be two stacked treasure chests.
McCully was almost certainly a Freemason; an 1874 letter from a lodge in Truro asks that "Mr McCully" keep the letter after it has been read to members. This has led sceptics like Dennis King to suggest that McCully may have embellished the narrative with Masonic symbolism - either as a fraternal in-joke or as a coded warning to fellow Masons that the treasure hunt was fraudulent. Whatever his motives, McCully's 1862 account became the source text that R.V. Harris, H.L. Bowdoin, and virtually every subsequent writer drew upon. He is, in effect, the man who wrote the Oak Island story into existence.
Melbourne "Mel" Chappell (c. 1905-1996) first set foot on Oak Island as a young man in 1931, working alongside his father William, uncle Renerick, and cousin Claude during the Chappells Limited expedition. After Frederick Blair's death in 1951, Mel acquired the Oak Island treasure rights and became the gatekeeper of the search for the next several decades.
Rather than mounting his own large-scale excavation, Mel controlled who could dig and on what terms, leasing portions of his rights to a series of treasure hunters. Among those who searched under Mel's authority were George Greene in 1955, the Harman brothers in 1958, Robert Restall in the early 1960s, and Robert Dunfield, whose controversial heavy machinery operations in 1965-66 dramatically altered the Money Pit landscape - lowering the surface elevation by roughly 11 feet and forever changing the site's topography.
Mel later partnered with Dan Blankenship, and the two became founding members of the Triton Alliance in the late 1960s - the syndicate that would drive the modern era of Oak Island exploration, including the drilling of the famous Borehole 10-X. Mel also rediscovered the stone triangle on the island's south shore in the spring of 1931, a feature originally found by Captain John Welling in 1897 and later relocated again by Amos Nauss during the Hedden expedition in the 1930s.
Mel Chappell remained connected to the Oak Island treasure hunt until his death in 1996, having spent over six decades tied to the mystery his father first drilled into. He represents the crucial bridge between the old era of individual prospectors and the modern corporate approach to the search.
In 1878, Sophia Sellers (née Graves) was ploughing a field on Oak Island's eastern end when the ground suddenly gave way beneath her team of oxen. One animal plunged into a well-like hole roughly eight feet in diameter and up to fifteen feet deep. A heavy wooden tripod was erected over the shaft to haul the ox out, and the hole was filled with boulders.
The sinkhole, located approximately 350 feet east of the Money Pit and 170 feet from Smith's Cove, became known as the Cave-in Pit. Its position - directly on the line between Smith's Cove and the Money Pit - convinced treasure hunters that it was a collapsed air shaft or ventilation tunnel used during the original construction of the flood tunnel system. When Frederick Blair later drilled into the Cave-in Pit, pick marks were visible on the hard clay walls, and oak timbers were found at depths of 62 and 100 feet - evidence that pointed to deliberate construction rather than a natural sinkhole.
Sophia was the daughter of Anthony Graves, one of Oak Island's early landowners. She and her husband leased portions of their land to successive treasure-hunting syndicates, including the Old Gold Salvage and Wrecking Company in 1909. She remains one of the very few women named in Oak Island's 230-year history, and her accidental discovery provided a crucial piece of physical evidence that the island's underground workings extended far beyond the Money Pit itself.
