Life of Galileo (German: Leben des Galilei), also known as Galileo, is a play by the twentieth-century German dramatist Bertolt Brecht with incidental music by Hanns Eisler.
The second (or 'American') version was written between 1945–1947, in collaboration with Charles Laughton. The play received its first theatrical production (in German) at the Zurich Schauspielhaus, opening on 9 September 1948. This production was directed by Leonard Steckel, with set-design by Teo Otto. The cast included Steckel himself (as Galileo), Karl Paryla and Wolfgang Langhoff.
The second version (in English) opened at the Coronet Theatre in Los Angeles on 30 July 1947. It was directed by Joseph Losey and Brecht, with musical direction by Serge Hovey and set-design by Robert Davison. Laughton played Galileo, with Hugo Haas as Barberini and Frances Heflin as Virginia. This production opened at the Maxine Elliott's Theatre in New York on 7 December of the same year. A third production, by the Berliner Ensemble with Ernst Busch in the title role, opened in January 1957 at the Theater am Schiffbauerdamm and was directed by Erich Engel, with set-design by Caspar Neher. The play was first published in 1940.
Galileo is a 1975 biographical film about the 17th century scientist Galileo Galilei, whose astronomical observations with the newly invented telescope led to a profound conflict with the Roman Catholic Church. The film is an adaptation of Bertolt Brecht's play of the same name. The film was produced and released as part of the American Film Theatre, which adapted several plays for a subscription-driven series of films from 1973 to 1975. Brecht's play was recently called a "masterpiece" by veteran theater critic Michael Billington, as Martin Esslin had in 1960. The film's director, Joseph Losey, had also directed the first performances of the play in 1947 in the US — with Brecht's active participation. The film is fairly true to those first performances, and is thus of historical significance as well.
The film closely follows the "American" version of Brecht's play Galileo. In 1609 Galileo is a mathematics professor in Padua, Italy. While his salary is inadequate, he possesses the freedom to pursue controversial scientific studies under the protection of the Venetian republic. Part of his work involves the use of a telescope, a relatively new scientific instrument brought from the Netherlands. Using the telescope, Galileo seeks to test the theories put forth by Nicolaus Copernicus that place the sun – and not the Earth – at the center of universe. As his research progress, Galileo accepts a more prestigious academic position in Florence, Italy. But his new position does not come with the government protection he enjoyed in Venice, and his friends in the higher echelons of the Roman Catholic Church refuse to come to his aid when he is summoned before the Inquisition.
