20th Century Technology Museum, Technology museum in Texas, United States.

The 20th Century Technology Museum is a technology museum in Texas featuring collections of machines, inventions, and devices from the 1900s. The exhibits show how innovation developed across different areas such as household use, industry, and communication.

The museum was founded to document the technological changes of the 20th century, from early household appliances to industrial machines. The collection shows how rapidly technology evolved during this period and affected different areas of life.

The museum occupies the first floor of the former Wharton County Jail, built in 1888. Its collection is mostly small domestic and office items — radios, phonographs, a jukebox, televisions, typewriters, cameras and early refrigerators — alongside farm equipment and arcade games. Most arcade machines can be operated by visitors, and staff demonstrate other working pieces.

The gallery occupies the first floor of the former Wharton County Jail, a building from 1888, so visitors should look for the old jail structure in Wharton rather than a purpose-built museum. Many arcade games and other machines can be operated by hand, so allow time to try them. The museum is a non-profit organization and opened its gallery in July 2005.

The museum displays original innovations from the 20th century, many of which are working examples that visitors can see in action. These working demonstrations help you understand how these technologies were actually usable in the past.
