Isidor Trauzl , also: Doro Trauzl , (born August 13, 1840 in Arad , Kingdom of Hungary, † March 10, 1929 in Baden near Vienna ) was an Austrian chemist and industrialist.

Life

Born into a family of officers, Trauzl joined the army and did scientific work on explosives. As a lieutenant he took part in the campaign against Prussia in 1866 and subsequently joined the Technical Military Committee in Vienna. In 1871 he was appointed captain.

In 1870 he and Alfred Nobel built the first Austrian dynamite factory in Jamky near Prague . From 1882 to 1892 Trauzl was general director at Dynamit-Nobel AG in Vienna. For several years he was the owner of a scythe factory at Kienberg-Gaming as well as a company for deep drilling technology in Hungary , Galicia and southern Russia .

From 1898 to 1904 Isidor Trauzl was active in the municipal council of the city of Baden near Vienna, where he made a special contribution as chairman of the committee for the construction of water pipes and sewage systems. As enforced by him, from 1902 various urban buildings and technical infrastructure structures were built under the financial responsibility of the municipality, for example the (no longer existing) municipal bathing and spa facility at the spa park.

The measurement method of the lead block bulge , which can be used to measure the explosive power of materials, is reminiscent of Trauzl's technical achievement . Among other things, Trauzl wrote a book on explosives entitled Dynamites and their use in agriculture . This first appeared in 1876. The following year he published the title Die Explosivstoffe der Gegenwart .

In 1925, on the occasion of his 85th birthday, his friends dedicated Das Trauzlbuch to the jubilee .

Isidor Trauzl died on March 10, 1929 in his (still existing) Baden villa, Grillparzerstraße 2; he was buried to rest on the 14th of the month in the Baden city cemetery.

With his wife Melitta, born von Foregger († September 14, 1904), he had a son, Isidor, a doctor in Baden sanatoriums, who died on August 30, 1924.
