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.
[3]
After his studies and years of research at the
University of Amsterdam , Van der Hammen arrived in
Bogotá in 1951.
[3]
Thomas van der Hammen analysed the
Bogotá savanna and concluded a great lake (Lake Humboldt ) was present there around 60,000 years BP, covering present-day Bogotá,
Soacha ,
Funza ,
Mosquera ,
Madrid ,
Cota , Chía and
Cajicá .
[4] 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 ,
[5]
Tunjuelo ,
[6] and
Subachoque Formations .
[7] His paleobotanical background proved valuable in dating the continental
Cacho Formation .
[8]
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.
