Professor Karl Heinz Rechinger HonFRSE (16 October 1906, Vienna – 30 December 1998, Vienna) was an Austrian botanist and phytogeographer. Life Karl Heinz Rechinger was born in Vienna on 16 October 1906. He was the son of Dr Karl Rechinger, then assistant at the Department of Botany in the Imperial Natural History Museum, and Rosa Elisabeth (Lily) Rechinger. Karl Heinz was raised in a refined, well-to-do Viennese family surrounded by art, music and science. He attended the prestigious Schottengymnasium in Vienna. Importantly, his father introduced him to botany, specimen collecting and how to carefully observe nature - activities that would shape his life and career. He accompanied his father on botanical excursions around Vienna, and learnt how to prepare and handle specimens, interpret labels and identify handwriting for material they brought back to a small private herbarium within their house. Rechinger married twice. He had two children with his first wife Frida. Career Rechinger studied botany, geography and geology at the University of Vienna. During this time, he began writing a thesis that revised part of the genus Rumex, and also worked as a paid demonstrator under Richard Wettstein in Vienna's Institute of Botany. He was awarded his Doctor of Philosophy on 15 May 1931. Despite an economic recession, he continued to work in the Department of Botany after graduating in volunteer or low-paid roles. In the early 1930s, Rechinger undertook many botanical excursions to Croatia, Greece, and the former Yugoslavia. Although only in his late-20s, he quickly became an expert on the flora of the Balkan Peninsula, having collected extensively from most countries in the area. In 1937, he was appointed provisional scientific assistant at the Natural History Museum in Vienna, where he would work for almost 35 years until his retirement in 1971. He was the museum's director from 1961 to 1971. Throughout this tenure, Rechinger continued to undertake botanical work. He travelled extensively in Iran, where he collected an impressive number of specimens. He also met and exchanged ideas with prominent contemporaries such as Heinrich Carl Haussknecht and Joseph Friedrich Nicolaus Börnmuller. Following the Anschluss, in which Nazi Germany annexed Austria in 1838, Rechinger was submitted to basic military training before serving as a clerk. Allied air raids against Berlin resulted in the almost complete destruction of the Botanical Museum Berlin-Dahlem, and also led to the evacuation of specimens from the Natural History Museum in Vienna.
