Lannach facility to avoid its capture by advancing Soviet forces. He refused, and after the second world war Brücher moved to Sweden thanks to Sven Hedin's invitation and worked with Svalof seed company. During this period he married Ollie Berglund, a Swedish plant breeder. He then moved to Argentina which was then under Juan Perón and received there in 1948, a professorship in genetics and botany at University of Tucumán (Tucumán, Argentina). He later worked in Caracas (Venezuela), Asunción (Paraguay) and then in Mendoza and Buenos Aires (Argentina). He also worked in Pretoria in 1964-65 where he claimed to have evidence for white superiority. In 1972 he served as biology advisor to UNESCO. Brücher wrote a number of books and papers on the history of grain (1950), origin, evolution and domestication of tropical plants (1977) as well as the monograph Useful plants of neotropical origin and their wild relatives (1989). He wrote biographical papers on Ernst Haeckel and helped prop him up as an icon for Nazi science ideals. He was critical of Vavilov in his publications possibly because he saw Vavilov as a communist and there had been other German botanists like Elisabeth Schiemann (1881–1972) who had supported his theory while holding anti-Nazi positions. After moving to South America, Brücher focused on ethnobotanical research and worked on the wild relatives of potatoes and beans. A species, Solanum brucheri named after him by Donovan Stewart Correll was found later to be a hybrid of S. acaule Bitt. And S. infundibuliforme Philippi (Hawkes and Hjerting, 1969). Brücher's wife who worked at the University of Caracas and one of his two sons were killed in the late 1960s at roadside checkpoint in Venezuela by a guard, apparently by mistake. On 17 December 1991 he was killed on his farm Condor Huasi (or Condor house, though a picture of a motif at its entrance suggests a Nazi eagle) in the district Mendoza (Argentina). His murder was claimed to be the result of a burglary but the case was never closed and no arrests were made. According to Daniel Gade, an associate from the University of Vermont, Brücher, was a vocal opponent of alcohol and drugs. Brücher even used the word "hygiene" when referring to addictions in his publication, a term from Nazi times and personally avoided alcohol and meat. Gade suggests, based on evidence available, that Brücher was working on strains of Fusarium
