Life and Career
Olbers was born in Arbergen, today part of Bremen, and studied to be a physician at Göttingen. After his graduation in 1780, he began practicing medicine in Bremen. 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.
On March 28, 1802, Olbers discovered and named the asteroid Pallas. Five years later, on March 29, 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, was the remnants of a planet that had been destroyed. The current view of most scientists is that tidal effects from the planet Jupiter disrupted the planet-formation process in the asteroid belt.
On March 6, 1815, Olbers also discovered a periodic comet, now 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 aged 81. He was twice married, and one son survived him.
Olbers' paradox, described by him in 1823 (and then reformulated in 1826), states that the darkness of the night sky conflicts with the supposition of an infinite and eternal static universe.
In 1804 he was elected a fellow of the Royal Society of London and in 1827 was elected a foreign member of the Royal Swedish Academy of Sciences.

Famous quotes containing the words life and, life and/or career:
“The feeling of being hurried is not usually the result of living a full life and having no time. It is on the contrary born of a vague fear that we are wasting our life. When we do not do the one thing we ought to do, we have no time for anything else—we are the busiest people in the world.”
—Eric Hoffer (1902–1983)
“His life itself passes deeper in nature than the studies of the naturalist penetrate; himself a subject for the naturalist. The latter raises the moss and bark gently with his knife in search of insects; the former lays open logs to their core with his axe, and moss and bark fly far and wide. He gets his living by barking trees. Such a man has some right to fish, and I love to see nature carried out in him.”
—Henry David Thoreau (1817–1862)
“They want to play at being mothers. So let them. Expressing tenderness in their own way will not prevent girls from enjoying a successful career in the future; indeed, the ability to nurture is as valuable a skill in the workplace as the ability to lead.”
—Anne Roiphe (20th century)
