Biography

Thomas van der Hammen was born in the city of Schiedam in South Holland, western The Netherlands and studied botany and palaeontology at Leiden University from 1944 to 1949. He was a deeply religious man.
After his studies and years of research at the University of Amsterdam, Van der Hammen arrived in Bogotá in 1951.
Thomas van der Hammen analysed the Bogotá savanna and concluded a great lake was present there around 60,000 years BP, covering present-day Bogotá, Soacha, Funza, Mosquera, Madrid, Cota, Chía and Cajicá. Van der Hammen has contributed greatly to the understanding of the geology of the Bogotá savanna and surrounding areas. He has worked with Gonzalo Correal Urrego towards an understanding of the prehistoric sites, as El Abra, Tequendama and Tibitó in central Colombia and has defined and described various geological formations, such as the Marichuela, Tunjuelo, and Subachoque Formations. His paleobotanical background proved valuable in dating the continental Cacho Formation.
In 2000, a natural reserve in the north of Bogotá bordering Chía and Cota, Thomas van der Hammen Natural Reserve, was named after the naturalist. The mayor of Bogotá, Enrique Peñalosa who ran twice for the Green Party, allowed for the construction of homes in the reserve, leading to protests of the people.
In 2003, Dr. van der Hammen granted a wide-ranging interview to Radio Netherlands about his work and his life.
