Boston Light – the first established light station in colonial America – began lighting the way for safe navigation into the fledging maritime port of Boston in 1716. The Fresnel Lens in the lantern room and fog signal apparatus situated on Little Brewster Island at the entrance to Boston Harbor continues today as an active Coast Guard maintained aid-to-navigation. However, its notoriety in the maritime community as the “the last manned Coast Guard Light Station” in the country is coming to closure with the retirement of Sally Snowman, its 70th keeper. A PowerPoint presentation provides photos of Boston Light’s 307 years of history and few photo anecdotes of Sally’s experiences as a 21st century keeper. RSVP through the library’s online calendar.
