Wilhelm von Biela

Wilhelm von Biela, born on March nineteenth, seventeen eighty-two in Roßla, Harz, was a distinguished German-Austrian military officer and an amateur astronomer. He hailed from a notable Protestant noble family that had its roots in what is now the Czech Republic. His lineage faced turmoil when Friedrich von Biela, the family patriarch, was executed in Prague during the religious wars of the early seventeenth century, leading to their exile to Saxony. Wilhelm was the last surviving member of this branch of the family.

After completing his studies at a military college in Dresden, Biela joined the Austrian army in eighteen hundred two, initially serving as a cadet in the Infantry Regiment 'Graf Stuart' Nr. 18. His military career saw him rise to the rank of captain of Grenadiers, where he actively participated in several campaigns against Napoleon between eighteen hundred five and eighteen hundred nine. Notably, in eighteen hundred thirteen, he served as an Adjutant to General Merveldt during the Battle of Leipzig, where he sustained injuries.

In eighteen hundred fifteen, Biela relocated to Prague to pursue his passion for astronomy under the tutelage of Martin Alois David. His career later took him to Italy, where he was appointed commandant of the town of Rovigo. Biela's astronomical work focused on the observation and calculation of cometary orbits, and he contributed significantly to the field with his publications in the Astronomische Nachrichten. His notable works included studies on comets, sunspot observations, and a comprehensive treatise on planetary rotation titled Die zweite grosse Weltenkraft, nebst Ideen über einige Geheimnisse der physischen Astronomie, oder Andeutungen zu einer Theorie der Tangentialkraft, published in Prague in eighteen hundred thirty-six.

Among his achievements, Biela independently discovered two comets, including the Great Comet of eighteen hundred twenty-three, C/1823 Y1, and made a significant independent discovery of his own: the periodic Biela's Comet, which later fragmented and disintegrated. In honor of his contributions, a lunar crater and the minor planet 2281 Biela bear his name.

Despite his notable public life, little is known about Biela's personal affairs. He was married to Anna (Edle von Wallenstern), and they had a daughter, Emilie Freiin von Biela, born in eighteen hundred twenty, who later married Moritz, Graf Forgách, another Austrian infantry officer, with whom she had two children. In the 1840s, Biela retired to Venice, where he passed away in eighteen hundred fifty-six.
