Celia Thaxter reigned over an impressive group of friends who were also the leading artists, musicians, and writers of the day.
These included Edward MacDowell and his wife; American pianist William Mason, son of Lowell Mason, who played the grand piano in her salon daily; and John Knowles Paine, America's first serious composer of note.
A charming small original daybook from this time period was re-published in part, in 1992, titled The Isles of Shoals Remembered, by Caleb Mason.
The most prominent feature on the island is a World War II concrete observation tower built to hold a radar installation.
For example, glacial plucking contributed to the whaleback shape of the island which is resultant of rock drumlin cliff faces.
