It was after her brother’s marriage, in 1788, that the majority of Caroline’s astronomical discoveries were made. She discovered her first comet in 1786, her eighth and last in 1797. She was recognised as a comrade by all the leading astronomers of Europe, and received many letters complimenting her on her discoveries. One from De la Lande addressed her as “Savante Miss,” while another from the Rev. Dr. Maskelyne saluted her as “My worthy sister in astronomy.” Royal and other distinguished visitors constantly visited the wonderful forty-foot telescope at Slough, and either William Herschel or his sister were required to be in attendance to explain its marvels. The Prince of Orange, on one occasion, called, and left an extraordinary message “to ask Mr. Herschel, or if he was not at home, Miss Herschel, if it was true that Mr. Herschel had discovered a new star, whose light was not as that of the common stars, but with swallow-tails, as stars in embroidery.” The only glimpse we get, through the peaceful labours of Caroline’s long life, of the strife and turmoil of the French Revolution, is the note she makes of the visit, to her brother’s observatory, of the Princesse de Lamballe. “About a fortnight after this,” the diarist observes, “her head was off.” The absence of all comment upon the wonderful political events of the time is noticeable, and so also is Caroline’s thinly-veiled contempt for any science less sublime than that to which she and her brother were devoted. Her youngest brother, Dietrich, was a student of the insect world. “He amuses himself with insects,” she wrote to her nephew; “it is well he does not see the word _amuses_, for whenever he catches a fly with a leg more than usual, he says it is as good as catching a comet.” Her brother’s marriage, though far from welcome at the time it took place, was a great blessing to her; for it gave her a most tender and affectionate sister, and ultimately a nephew, the inheritor of his father’s great gifts, and the being to whom, after William Herschel’s death in 1822, Caroline transferred all the devoted and passionate attachment of which her nature was capable.
