In page Arnold Adolph Berthold:

"

Berthold was the second-youngest of six children. His father was a carpenter and his family was not wealthy. He went to the local gymnasium (equivalent to a grammar school) where he studied the classics but was most interested in natural history. He followed his older brother's example to study medicine at University of Göttingen in August 1819. His thesis was under the direction of Johann Friedrich Blumenbach (1752–1840) and he qualified on 10 September 1823.[1]
