Friedrich Schickendantz (also known as Federico Schickendantz) (15 January 1837-4 April 1896) was an Argentine-German scientist who worked in the fields of mineralogy, chemistry, botany, geology, and meteorology. He was born in Landau, now in the Rhineland-Palatinate state of Germany. He studied chemistry and mineralogy at the University of Munich and the University of Heidelberg, under the direction of Robert Bunsen.
Schickendantz was one of the attendees of the 1860 Karlsruhe Congress. In 1861, while he was at Oxford, he decided to take a job at a mine in Pilciao, Andalgala, in the Argentine province of Catamarca. The mine, called Casa Lafone, was owned by Samuel Fisher Lafone. Schickendantz worked at the mine until 1868; during this time he became a close friend of the supervisor of the mine, Samuel Lafone Quevedo, son of Fisher Lafone and developed what became known as the Schickendantz method for separating gold from copper.
Schickendantz also studied the plants in the region of Catamarca, many of which were still unknown in Europe. He made contributions to the study of alkaloids found in these plants, some of which eventually found therapeutic uses. Some species that were named after him include Gymnocalycium schickendantzii, Echinopsis schickendantzii, Trichocereus schickendantzii, Opuntia schickendantzii, Bulnesia schickendantzii, and Euphorbia schickendantzii.
