Endowed (visiting) professorships
Endowed professorships are established using funding provided by foundations and/or patrons. Endowed professors are usually appointed for a period of five or ten years. After the funding ends, Humboldt-Universität maintains the endowed professorships without external funding. Endowed professors have the same rights and duties as other professors at Humboldt-Universität and do not take orders from the organisations or individuals that fund the professorship.
There are also endowed professorships for visiting professors, who spend a limited period of time at the University.
