Friedrich Wilhelm Bessel (July 22, 1784 - March 17, 1846) Wilhelm Bessel was born in Minden on July 22, 1784 as the son of Carl Friedrich Bessel, a government secretary, and his wife Friederike Ernestine (b. Schrader), daughter of a pastor from Rehme, as one of 9 children (3 sons, 6 daughters); the family originated from the Calenberg village near Hannover. After getting school education in Minden, he went to Bremen in January 1799 at age 14, to work in import-export business for the Andreas Kuhlenkamp company, with a contract for a 7-year apprenticeship. During this time, besides his business activities, he trained himself the skills necessary to undertake naval overseas voyages: First geography, Spanish and English, then navigation, astronomy and mathematics; he took a course in navigation in 1801. Astronomy finally caught his interest. In 1804, he contacted Wilhelm Olbers (1758-1840) concerning a paper he had written on comet Halley, using data from observations made by Harriot in 1607. Olbers advised him to elaborate this work further, and it was finally published. On Olbers suggestion, Bessel accepted a post at Lilienthal Observatory, a private observatory near Bremen, owned by Johann Hieronymus Schroeter (1745-1816) in 1806. There he did observational work on comets and planets, in particular planet Saturn and its moons and the newly discovered asteroids Ceres, Juno and Vesta, studied atmospheric refraction, and started to re-investigate astrometric observations of Bradley (1692-1762).

Bessel, Friedrich Friedrich Wilhelm Bessel, b. July 22, 1784, d. Mar. 17, 1846, a German astronomer and mathematician, is best known for his determination of the first stellar PARALLAX, the earliest accurate method for measuring stellar distances. Bessel had little formal schooling but when, at the age of 26, he was appointed director of Frederick William III of Prussia's new Konigsberg Observatory, he was granted the title of doctor by the University of Gottingen. Bessel remained at Konigsberg for the rest of his life, and it was there that his monumental astrometrical program of determining the positions and proper motions of stars led to the discovery (1838) of the parallax of 61 Cygni. Bessel also worked out a method of mathematical analysis involving what is now known as the Bessel function, a still indispensable tool in physics and engineering. Author: Alexander Velásquez.

Friedrich Wilhelm Bessel Wilhelm Bessel attended the Gymnasium in Minden for 4 years but he did not appear to be very talented, finding Latin difficult. The fact that he later became proficient in Latin, teaching himself the language, probably suggests that the Gymnasium failed to inspire Bessel. At the age of 14, he left school to become an import-export apprentice in Bremen. At first Bessel received no salary from the firm, but as his accounting skills became appreciated by the firm he received a small salary. Interest in the countries his firm dealt with led Bessel to spend his evenings studying geography, Spanish and English. His interests turned towards navigation and he considered the problem of finding the position of a ship at sea. This in turn led him to study astronomy and mathematics and he began to make observations to determine longitude. Bessel's work had now become known internationally, and he was honored with the award of the Lalande Prize from the Institut de France for his tables of refraction based on Bradley's observations. He used Bradley's data to give a reference system for the positions of stars and planets and also to determine the positions of stars. He had to deduce errors in Bradley's instruments and errors caused by refraction. He had to reduce the positions to one fixed date and eliminate the effects of the Earth's motion, the precession of the Earth and other effects. Bessel's work in determining the constants of precession, nutation and aberration won him many honors. in 1812, he was elected to the Berlin Academy, and won a prize from the Berlin Academy in 1815. In 1825 he was honoured by election as a Fellow of the Royal Society.
