November 15, 1738 William Herschel was born. Although his accomplishments in astronomy range beyond this, he is most remembered as the discoverer of the planet Uranus.
Frances Rolleston liked to point out, however, that the true discoverer was not William but his sister Caroline. As an artist and writer, Frances was sensitive to the prejudice against women's accomplishments.
"Caroline Herschel discovered the Uranus, Mrs. Somerville has written well on science, but still a woman's name is a great detriment to any work except a novel." (1862)
"Remember Caroline Herschel's discovery of the Uranus, by mapping out the stars of Virgo, and, said her brother, 'one too many,'—she persevered, and he was convinced. Many a lively anecdote have I had of that pair, from her German friends, how she got up at 8 p.m. and made short breakfast, and after that both flanneled up for the midnight happy occupation, and went to bed at morning dawn." (1863)
Here is an article on Herschel that gives more credit to Caroline than we usually hear of.
