The Caller, Bronze sculpture series in Berlin and Bremen, Germany.

Der Rufer is a bronze figure by Gerhard Marcks, created in 1966 for Radio Bremen: a barefooted man in a robe who cups his hands to his mouth as if shouting. Casts stand in Bremen, Perth, Aachen and near the Brandenburg Gate in Berlin's Tiergarten.

Gerhard Marcks created the bronze sculpture in 1966 for Radio Bremen, originally commissioned for a telecommunications building in Bremen. A cast was presented to the Art Gallery of Western Australia in Perth by CSR Limited in 1982, and another was installed near the Brandenburg Gate in Berlin in 1989, shortly before the Wall fell.

The Berlin version carries a peace message inscription that emphasizes communication and solidarity between people during times of social division. This message is reinforced by the man's gesture of calling out with cupped hands around his mouth.

Multiple versions of this bronze figure stand in different locations, making it possible to see them at several sites. The original in Bremen and the Berlin version are both easily reached on foot, while additional copies exist internationally.

A copy in Perth, Australia was dedicated in 1998 to torture victims and survivors, transforming its meaning beyond the original communication theme. This dedication shows how the same sculpture can gain new layers of meaning in different contexts.
