Friedrich Wilhelm Bessel

Born 22 Jul 1784; died 17 Mar 1846 at age 61.German astronomer who spent his entire career from age 26 (appointed 1809) as director of Frederick William III of Prussia's new Königsberg Observatory and professor of astronomy. His monumental task was determining the positions and proper motions for about 50,000 stars, which allowed the first accurate determination of interstellar distances. Bessel's work in determining the constants of precession, nutation and aberration won him further honors. Other than the sun, he was the first to measure the distance of a star, by parallax, of 61 Cygni (1838). In mathematical analysis, he is known for his Bessel function.
