Statue of Alexander von Humboldt, Berlin, Marble monument at Humboldt University, Berlin, Germany.

The Alexander von Humboldt Memorial is a 2.50-metre marble sculpture by Reinhold Begas, unveiled on 28 May 1883 to the right of the main building of Humboldt University on Unter den Linden. Humboldt sits on a tree stump in contemporary dress, facing straight ahead, his right hand holding a plant and his left arm resting on an armrest. A globe at his lower left refers to his research travels; the 3.20-metre pedestal bears the inscription "ALEXANDER / VON / HUMBOLDT" beneath playing children and reliefs with allegories of his fields of study.

A competition in 1876 was won by Paul Otto's design, but the monument was executed in 1882 by Reinhold Begas in neo-baroque style. It was unveiled on 28 May 1883 together with the Wilhelm von Humboldt memorial, to the right of the Palais des Prinzen Heinrich, now the Humboldt University main building. In 1939 the University of Havana added an inscription calling Humboldt the "second discoverer of Cuba".

On the pedestal, below playing children, reliefs show allegories of Humboldt's fields of research. In 1939 the University of Havana added the Spanish inscription "AL SEGUNDO DESCUBRIDOR DE CUBA / LA UNIVERSIDAD DE LA HAVANA 1939", calling him the second discoverer of Cuba. A mnemonic helps visitors: Wilhelm faces Wilhelmstrasse, Alexander faces Alexanderplatz.

The monument is located on Unter den Linden in front of Humboldt University, a busy area with many other historic buildings. The site is easy to reach on foot and is frequently passed by visitors to the museum and university.

The pedestal bears an inscription added in 1939 by the University of Havana: "AL SEGUNDO DESCUBRIDOR DE CUBA", calling Humboldt the second discoverer of Cuba. A mnemonic helps locate the pair of statues: Wilhelm faces Wilhelmstrasse, Alexander faces Alexanderplatz. Plaster casts of both sit on the Adlershof campus, Alexander's in the Institute of Geography.
