# History of the Geodesic Dome

> Geodesic domes, spherical frames of triangles, were first built by Walther Bauersfeld in Jena in the 1920s and popularised by Buckminster Fuller after 1948.

## Key facts

- **First geodesic dome:** Walther Bauersfeld, Zeiss, Jena (1920s)
- **Jena planetarium opened:** 18 July 1926
- **Fuller's US patent:** 29 June 1954
- **Largest (Guinness, 2021):** Jeddah Super Dome, 210 m (690 ft)

A **geodesic dome** is a spherical or part-spherical shell made from a network of triangles. Because triangles are rigid, the structure spreads loads across the whole frame, enclosing a large volume with little material and no internal columns. Geodesic domes have been used to roof planetariums, exhibition pavilions, attractions and homes.

## Bauersfeld and Jena

The first geodesic dome was designed after the First World War by **Walther Bauersfeld**, chief engineer of the optical company **Carl Zeiss Jena** in Germany, to house a planetarium projector. Bauersfeld received a German patent on 19 June 1925. A small dome was built on the roof of the Zeiss works, and the larger planetarium known as "The Wonder of Jena" opened to the public on **18 July 1926**.

## Fuller

The American designer **Buckminster Fuller** developed the idea independently. In 1948-1949, at Black Mountain College, he experimented with domes with the artist Kenneth Snelson and coined the term "geodesic". He received US patent 2,682,235 on **29 June 1954**. Fuller is often mistakenly credited as the inventor, but he did more than anyone to popularise the dome.

## Milestones

- **1953:** the oldest surviving Fuller-built dome is erected by students in three weeks at Woods Hole, Massachusetts.
- **From 1954:** military tests showed a 9.1 m (30 ft) dome could be carried by helicopter at about 93 km/h (50 knots) without damage.
- **1967:** the US Pavilion dome at Expo 67 in Montreal, by Fuller and Shoji Sadao. Its covering later burned, but the frame survives as the Montreal Biosphère.
- **1982:** Spaceship Earth opened on 1 October at Epcot, Walt Disney World, Florida.

## Records

As of May 2021, Guinness World Records listed the **Jeddah Super Dome** in Saudi Arabia, 210 m (690 ft) across, as the largest geodesic dome. The larger Seagaia Ocean Dome in Japan (216.5 m) was demolished in 2017.

## Other large domes

Other very large examples include the Poliedro de Caracas in Venezuela, about 143 m (469 ft) across, and the Ruwais Refinery Dome, about 135 m (443 ft).
