Ignaz Rojacher

Ignaz Rojacher (born April 3, 1844 in Gaißbachtal near Rauris ; † January 4, 1891 ) was the owner of the mine and builder of the Sonnblick observatory on the Hohen Sonnblick in the Rauris Valley in the Hohe Tauern .

Life

Ignaz Rojacher came from a miner's family and was born as the son of the miner carpenter Jörgl and the mother Anna Rojacher in the Gaißbachtal. From 1856 onwards, at the age of 12, he was already working as a chest runner in the gold mine , where he had to push so-called mine trucks loaded with ore. He learned the carpentry and became a carpenter in gold mining. As a carpenter, he was responsible for maintaining the tunnels, shafts and the inclined elevator.

In 1870 he was promoted to washman in the gold mine in Kolm-Saigurn , where he worked as an overseer for ore processing. In 1872 he was sent to the mining academy in Příbram ( Bohemia ) for four weeks to deepen his mining knowledge. In 1876 he became the tenant of the mining facilities in Kolm-Saigurn. With 25 to 30 men, 15.378 kilograms of gold and 38.175 kg of silver were extracted from 472 tons of ore in 1876/77 .

In 1880 Rojacher finally bought the gold mining company in Kolm-Saigurn for 4,500 guilders (approx. 330,000 euros ). Through technical improvements he once again briefly led gold mining to a modest boom. In 1880 he built the runway from the wheel house to the miner's house . He also installed a telephone connection from Kolm-Saigurn to the Knappenhaus. Rojacher also visited the world exhibition in Paris ( France ) and brought one of the first electricity generators in Europe to Salzburg. To illuminate the new inn he built in Kolm-Saigurn, he used water power to generate electricity for 15-watt light bulbs.

In 1885 he went on a study trip to Falun ( Sweden ) together with his friend and sponsor Wilhelm Ritter von Arlt , where he got to know a new extraction method . In the course of this trip, Arlt and Rojacher came across skis for the first time , which they brought back to Rauris, where Arlt was one of the first to write Austrian ski history.

In 1879 meteorologists from all over the world met in Rome ( Italy ) to clarify the question of the nature of the earth's atmosphere in the higher air layers. Since Rojacher was also an excellent weather observer and since the Viennese meteorologist Julius Hann , director of the Central Institute for Meteorology (today ZAMG ), was fascinated by him, the idea arose to build a weather station on the summit of the Hohe Sonnblick . In 1886, for example, Rojacher built the Sonnblick observatory , one of the most important weather, climate and environmental observatories in the Alps . A telephone connection from the Hohen Sonnblick to the Centralanstalt was also installed from the start. For the construction of this high alpine weather station he was awarded the Cross of Merit with the Crown by Emperor Franz Joseph I.

In 1888, the postmaster's position in Rauris was acquired, enabling a daily connection from Taxenbach to Kolm-Saigurn. In 1889 Ignaz Rojacher sold the mining operation to a Belgian speculation company, which had to stop mining immediately.

In the years 1886/87 a Rauris section of the Alpine Club already existed under the direction of Rojacher. Ignaz Rojacher died in 1891 at the age of only 46. Wilhelm Ritter von Arlt had the Rojacher Hut built in 1897 in honor of the pioneer for the German and Austrian Alpine Club Section Rauris .
