Carl Ludwig Doleschall

Carl Ludwig Doleschall (Karol Ľudovít Doležal ; Hungarian: Doleschall Lajos) (born 15 July 1827 – died 26 February 1859) was born in Nové Mesto nad Váhom (=Hu: Vágújhely), Slovakia (then Hungarian Kingdom, inside Austrian Empire), as the son of the theologian Michael Doleschall, and died in Ambon Island, Moluccas, only 31 years old. His name is sometimes also written as "Doleschal".

He studied medicine at the University of Vienna and became a military surgeon for the Dutch army, stationed in Java in 1853. He studied invertebrates and plants extensively, and described many arachnids and insects, notably diptera. In 1852, he published the work Systematisches Verzeichniß der im Kaiserthum Österreich vorkommenden Spinnen. He spent the last half of his life mostly in the island of Ambon in Indonesia.

He was visited by the British naturalist Alfred Russel Wallace in 1857. Shortly after Wallace left, he died of consumption in February 26, 1859. After his death his large collection of beetles went to the Hungarian National Museum in Budapest.
