Hans Poelzig, German architect, designed the IG Farben Building and Großes Schauspielhaus (died 1936)

Hans Poelzig was a German architect, painter and set designer.

The I.G. Farben Building – also known as the Poelzig Building and the Abrams Building, formerly informally called The Pentagon of Europe – is a building complex in Frankfurt, Germany, which currently serves as the main structure of the Westend Campus of the University of Frankfurt. Construction began in 1928 and was complete in 1930 as the corporate headquarters of the I.G. Farben conglomerate, then the world's largest chemical company and the world's fourth-largest company overall.

The Großes Schauspielhaus was a theater in Berlin, Germany, designed by architect Hans Poelzig for theater director Max Reinhardt. The structure was built as a market hall in 1867 and then served as a circus and event venue. Poelzig transformed it into an Expressionist venue in 1919, when it began to host Reinhardt's productions. The design featured a domed ceiling with stalactite-like decorations, indirect lighting and palm-like light columns in the foyer. The house later hosted revue and was used by the Nazis for propaganda. After World War II it reopened as a variety house. Severe foundation damage led to its closing in 1980 and demolition in 1985.
