The secret to a long marriage...

The secret to a long marriage is that we take time to go to a restaurant two times a week. A little candlelight, dinner, soft music and dancing. She goes on Tuesdays. I go on Fridays.

John Wrottesley

Born 5 Aug 1798; died 27 Oct 1867 at age 69.John Wrottesley, 2nd Baron Wrottesley, was an English astronomer, who published Catalogue Of The RA Of 1318 Stars. He was a founder member of the Royal Astronomical Society. From his first Observatory in Blackheath, London, he recorded over 12,000 observations. After he inherited the title and the Staffordshire family estate at Wrottesley in 1841, he built an observatory there. In 1855, the city of Wolverhampton nearby decreed that if any ... furnace chimney ...was built ... within three miles of the observatory, it shall be constructed on the best and approved principles “for consuming the smoke arising ... therefrom.” This of course was so that observations from the observatory would not be hampered by smoke pollution.
