Heinrich Wilhelm Olbers

Heinrich Wilhelm Matthäus Olbers (October 11, 1758 – March 2, 1840) was a German astronomer, physician and physicist.

[edit] Career

He was born in Arbergen, near Bremen, and studied to be a physician at Göttingen. After his graduation in 1780, he began practicing medicine in Bremen, Germany. At night he dedicated his time to astronomical observation, making the upper story of his home into an observatory. He also devised the first satisfactory method of calculating cometary orbits.

**Asteroids discovered: 2**
2 Pallas	March 28, 1802
4 Vesta	March 29, 1807

In 1802, Olbers discovered and named the asteroid Pallas. In 1807 he discovered the asteroid Vesta, which he allowed Carl Friedrich Gauss to name. As the word "asteroid" was not yet coined, the literature of the time referred to these minor planets as planets in their own right. He proposed that the asteroid belt, where these objects lay, were the remnants of a planet that was destroyed. This theory is now discarded by most of the scientific community.

On March 6, 1815, Olbers also discovered a periodic comet named after him (formally designated 13P/Olbers).

Olbers was deputed by his fellow-citizens to assist at the baptism of Napoleon II of France on June 9, 1811, and he was a member of the corps legislatif in Paris 1812-1813. He died in Bremen at the age of eighty-one. He was twice married, and one son survived him.

Olbers' paradox, described by him in 1823 (and then reformulated in 1826), is the paradoxical observation that the night sky is dark, when in a static universe the night sky ought to be bright. it is one of the pieces of evidence used in support of a non-static Universe such as the current Big Bang model.
