Johann Ludwig Christian Gravenhorst

However, the death of his father two years later left him a great fortune; so he was able to change his direction.

He went to Paris in 1802 and there met Georges Cuvier, Pierre André Latreille, and Alexandre Brongniart.

Parallel to his studies, he assembled, thanks to his financial means, a very important natural history collection.

He started to suffer from mental disorders after 1825, stopping all scientific work in the year 1840, and withdrawing completely into himself in 1856.

[1] Gravenhorst appears to be also responsible for naming Arthropoda in 1843, which had previous been erroneously attributed to other authors.
