On this day in 1851 – April 12th – English astronomer Edward Walter Maunder was born in London.
He was a founder member of the British Astronomical Association, but is probably best remembered for his solar observing and the study of sunspots, in particular his discovery that very few sunspots had been seen during the years 1645 to 1715. This period is now known as the Maunder Minimum.
