April 15 – 43 Ariadne

Today’s birthday is Friedrich Georg Wilhelm Von Struve.  Von Struve was born in Holstein (now in Germany, but then part of the united kingdom of Denmark-Norway) on April 15, 1629.

He was a keen observer of double stars, and published measurements of over 2,000 in his Stellarum duplicium et multiplicium mensurae micrometricae.  Despite this he still found the time to father 18 children to two wives.

1857  –  Asteroid 43 Ariadne was discovered today in 1857 by Sir Robert Norman Podgson, KBE.  Ariadne was the second of eight asteroids he discovered.  It is also the name of a Hawaiian Goose I adopted at the Wildfowl & Wetland Trust’s Martin Mere site in Lancashire some years ago, but that’s neither here nor there.
