Maybe its a Boston thing but there's been plenty of women lighthouse keepers in the rest of the US for 250 years:

Not all of these are "lighthouses", per se. Nixes Mate is actually just a concrete-and-paint reflector: https://en.wikipedia.org/wiki/Nixes_Mate
It's been kind of a fantasy for me to live in this lighthouse, I'm very tempted to apply for the job. Too bad it's not possible to live there anymore.
One time we arrived at Little Brewster and I was wearing a "captain's hat" that some friends had gotten me from West Marine, and the Coast Guard auxiliarists who helped us dock gave me a hard time, Boston-style. I think they don't love it when recreational sailors wear pretend rank insignia. They were smiling about it but I didn't wear the hat on later visits!
I hope she has a great retirement and they find somebody even half as dedicated to be her successor. The only reason Boston Light still has a keeper at all (the only one left in the country) is because Ted Kennedy and John Kerry sponsored an amendment to the 1989 Coast Guard Authorization Act to the effect that "The Boston Light shall be operated on a permanently manned basis." I just went back to look at it and in Ted Kennedy's remarks he says, "Thousands of visitors a year come out in Boston Harbor to visit to Boston Light. They learn about the history of the Light from the museum exhibits at its base. They climb the historic tower, and enjoy the view of the Boston skyline and the charm of Little Brewster Island. Most important, they gain a new understanding and appreciation of the important work of the Coast Guard and the role of Boston Light in our Nation's history." The part about thousands of visitors coming out I think is sadly no longer true. :-(
