The first keeper of the lighthouse was William A. Guthro, who moved up to Addenbroke with his wife Edith from Nanaimo. Keeper Guthro served until 1921, except for a four-and-a-half-month span in 1918, when he was on sick leave and Hugh Anderson was placed in charge of the station. When the Guthros left in 1921, Robert Smith and his wife Edith moved over to Addenbroke from Cape St. James Lighthouse. Keeper Smith fell ill in March 1922 and passed away in a Vancouver hospital on May 9, 1922.
Edith Smith valiantly elected to take over as keeper of Addenbroke Lighthouse, where her closest neighbors were ten kilometres away in Safety Cove on Calvert Island. “Time did drag sometimes,” she later admitted, but “every now and then, fishing boats would call in for a visit. I used to fish often…there were many things to take my mind off the solitude and loneliness.” Edith must have had an occasional visitor at the lighthouse, as on October 20, 1924, she married Walter Brydon, who had been working as a mariner engineer in Bella Bella, seventy-five kilometres by boat from Addenbroke Island.
It appears that Brydon took on the responsibility of keeper after the marriage since his name appears in the Department of Marine records from 1924 until 1928, when the Brydons swapped stations with Ernest Maynard, who had been serving for two years at Lucy Island near Prince Rupert.
The decision to leave Lucy Island proved to be a tragic one for Maynard. On the morning of August 16, 1928, Calvert Thorpe neared Addenbroke Island, and when he noticed the light was still burning, he decided to check on the keeper. Thorpe found Keeper Maynard splayed on the ground near the boathouse with half of his head blown away.
Although suicide was considered as a possible cause, authorities who examined the crime scene concluded that Keeper Maynard had been awakened by a commotion at the station’s dock and had been shot when he went to investigate. Maynard was wearing unlaced shoes over his bare feet, and the keys to the lighthouse were found on the boardwalk next to his body. The only clues found nearby were a white button that didn’t match any of the keeper’s clothing and a few drops of red paint found in the shed on the wharf.
The B.C. Provincial Policed checked into Hannah’s past at Stone’s request and learned that the drifter had spent time behind bars on three different occasions for stealing horses, beating a man, and committing robbery. Stone paid another visit to Safety Cove and this time noted Hannah’s freshly painted skiff and his collection of paints that just happened to match some used by the Marine Department.
Hannah rightly began to suspect that he had become the primary suspect in the investigation, and when Stone returned for another visit, he found the following note inside Hannah’s tent:
Safety Cove Calvert Island B.C.Mannuel Hannah was never seen again in Fitzhugh Sound.
Sept. 18th 1928

An unwanted visitor of another sort paid a visit to Addenbroke Island in April 2006, when Dennis Rose was serving there. Keeper Rose was busy building crates in preparation for his imminent move, and every time he would start the Skill saw or use a drill, a curious Grizzly bear would be drawn out of the woods. Keeper Rose decided to try out the pepper spray the Coast Guard had given him the previous year, but when he failed to take into account the wind direction, the only ones affected by the blast were himself and his dog. After the bear had been hanging around the station for ten days, Keeper Rose had just about decided he might have to put him down when Fish and Wildlife said that they would relocate him to an area where there were lots of females and no males. The bear must have caught wind of the plan as he disappeared just before the Fish and Wildlife showed up and never bothered the station again.
A new single dwelling was built on Addenbroke Island in 1961 by McGinnis Construction, and in 1968 a light atop a skeletal tower replaced the lantern room atop the old dwelling. The white round tower from which the light at Addenbroke Island is displayed today was erected in 1998.
