Federico Carlos Lehmann

Federico Carlos Lehmann Valencia (March 23, 1914 – 1974) was a Colombian ornithologist, plant collector, and conservation biologist.

Early years
Lehmann Valencia was born in the city of Popayán, in Cauca, Colombia. His grandfather, Friedrich Carl Lehmann, a Colombia-based German explorer, had died while crossing the Río Timbiqui; his father, Federico Carlos Lehmann Mosquera was widowed when his son was born, and Lehmann Valencia was largely brought up by his grandmother who encouraged his interest in geography and natural history. Lehmann Valencia studied at the University of Cauca in Popayán from 1929 to 1934.

Career
In 1938 Lehmann Valencia accepted a job in the Institute of Botany at the National University of Colombia in Bogotá.

From 1956 to 1961 Lehmann Valencia was the assessor of natural resources for the Ministry of Agriculture in the departments of Valle and Cauca, his work leading to the creation of new protected areas, the Laguna de Sonso Nature Reserve, the Farallones de Cali National Natural Park, the Puracé National Natural Park, and the Los Nevados National Natural Park. He also took part in a project at the University of Valle in Cali, collecting and classifying the birds of western Colombia. In 1963 he founded the departmental Museum of Natural Sciences in Cali which was named after him after his death in 1974.
