Baron Wilhelm von Biela

Baron Wilhelm von Biela (; March 19, 1782 – February 18, 1856) was a German-Austrian military officer and amateur astronomer.

Wilhelm von Biela was born in Roßla, Harz (Northern Germany). He was a descendant of a prominent Protestant noble family originally from what is now the Czech Republic, the family having been exiled to Saxony after its head, Friedrich von Biela, was executed in Prague in 1621 during the religious wars of the period. Biela was the last member of his branch of the family.

After study at military college in Dresden, Biela joined the Austrian army in 1802, serving as a cadet in the Infantry Regiment 'Graf Stuart' Nr. 18. He rose to the rank of a captain of Grenadiers and participated in a number of military campaigns against Napoleon between 1805, 1809 and later on. In 1813 he was an Adjutant to General Merveldt at the Battle of Leipzig, where he was wounded.

In 1815 Biela went to Prague, where he commenced study of astronomy under Martin Alois David.

In the field of astronomy, he specialized in observing and calculating the orbits of comets. He also did some sunspot observations and published a series of articles, mostly in the Astronomische Nachrichten, on subjects such as comets, the theoretical considerations of comets "falling into the Sun", Tycho Brahe, and occultations of stars by the Moon.

In the 1840s Biela retired to Venice, where he died in 1856.

The minor planet 2281 Biela is named in his honor.
