Wilhelm Lenk von Wolfsberg

Nikolaus Wilhelm Freiherr Lenk von Wolfsberg (born March 17, 1809, Budweis, Austria; died October 18, 1894, Troppau, Austria) was an Austrian officer (Feldzeugmeister), owner of the Corps Artillery Regiment No. 4 and scientist.
Biography.
The young Wilhelm was adjusted in the Artillery regiment Nr. 4 in 1823. He completed the higher course of his artillery training in the Austrian military training centres and the Bombardier Corps in 1826, moved there in 1831 to lieutenant. In the following years, Lenk served as commander of a Bombardier detachment in the federal fortress of Mainz. In 1839, he became first lieutenant in the Field Artillery Regiment Nr. 1, then in 1848 Lieutenant Commander at Prague, as a captain in 1849 at Peterwardein and 1851 at Vienna in the artillery stuff-administrative district of the 2nd Artillery regiment. He was assigned to the General Division Artillery and promoted to major at the end of 1852. Now he could completely dedicate his time to his work in the field of technical chemistry.
On 1 April 1854, he was appointed lieutenant colonel and chairman of the second Department of General Artillery Directorate (Director of guncotton centre). He remained in this position until he promoted, out of the ranking tour, on 19 February 1861 to brigadier general and was entrusted with the management of the Artillery Committees, then in 1862 followed the appointment as national director of artillery in Vienna.
In this function he became the second owner of the Artillery Regiment No. 1 "Kaiser Franz Joseph" in 1866 and earned through the armouring of the bridgehead Floridsdorf, the fortified camp near Vienna, as chief of artillery great merits during the war of 1866. Therefore, the emperor promoted him on November 9, 1867 (rank from November 13 of the year), to major general (Feldmarschalleutnant), and in 1871 he appointed Wolfsberg to the owner of the Corps Artillery Regiment No. 4. In April 1875, he entrusted him with the command of the fortress of Olmütz, which he headed until his retirement.
On April 1, 1877, he got the rank of Feldzeugmeister and retired at his own request.
Technical achievements.
The Baron occupied himself in 1849 with technical work, especially intensive with the improvement and consolidation of the gun cotton trinitrocellulose. He tried to use the guncotton as blowing agent for guns. Therefore, the “K. K. Ärarische Schießwollanstalt” in Hirtenberg, a predecessor of today existing arms factory Hirtenberger AG, was established in 1851. The later Feldzeugmeister succeeded in generating a Trinitrocellulose [C12H7(3NO4)O10], that met the military requirements for durability, uniform combustion with high combustion rate and temperature insensitivity up to an ignition point of 136 °C.
Wolfsberg patented the process about his method of controlled compression of the fibre at the guncotton on June 4, 1864. Therefore, he was asked to give lectures in England and France. In France, he was allowed to report Emperor Napoleon III. personally and received from his hand the Commander's Cross of the Legion of Honour and a box provided with his initials and ornate with diamonds. However, by the end of 1865 the production was abandoned prematurely in fear of spontaneous combustion in Austria, due to explosions in two magazines.
Anastasius Grün wrote: "It was a fatal rashness that the method to use guncotton as blowing agent in guns, developed by Major General Lenk of Wolfsberg, was not pursued further after the explosion of a depot. Finally, it was just the Austrian artillery, whose officers and graduates of the Engineering Academy were the main victims of the defeat at the Battle of Königgrätz: the battery of the dead." 
Furthermore, Wilhelm invented a good corroborating percussion fuse, a shrapnel grenade, and collapsible tubes for mountain guns. He also gave a construction of the so-called wedge traits for rifled guns. The results convinced and had to go in equipping 30 field batteries.
Performance from today's perspective.
His performance is still not forgotten.
Family.
Wilhelm was the son of Jacob Freiherr Lenk von Wolfsberg, Colonel and Knight of the Military Order of Maria Theresa. He married on June 24, 1833 in Mainz Eveline Aloisia Schreher (b. November 2, 1810, Mainz; d. January 7, 1871, Troppau). They had five children. Rudolf (1834-1907), the eldest son, was an Austrian General, too. One of his daughters, Malwine (1839-1866), married the Austrian General Constantin Buol von Wischenau (1822-1893), the youngest, Friederike Berta (1843-1906), was the spouse of the deputy of the Austrian Imperial Council and large landowner’s Karl Freiherr Putz von Rolsberg (1852-1921). She was the ancestress of the children of Count Alexander, son of Baron Alexander Wassilko von Serecki.
