Bessel, Friedrich Wilhelm

(1784--1846)

Mathematician and astronomer, born in Minden, Germany. In 1810 he was appointed director of the observatory and professor at Königsberg. He catalogued stars, predicted a planet beyond Uranus as well as the existence of dark stars, investigated Johann Kepler's problem of heliocentricity, and systematized the mathematical functions involved, which now bear his name.
