Underwood & Underwood was an early producer and distributor of stereoscopic and other photographic images, and later was a pioneer in the field of news bureau photography.

Underwood & Underwood, founded in 1881 by brothers Elmer and Bert Underwood in Ottawa, Kansas, became the world’s largest publisher of stereoviews, producing up to 10 million views annually. They expanded their business by developing a unique sales system using college students and acquiring other companies like Jarvis, Bierstadt, and William H. Rau. By 1901, the company was producing 25,000 stereographs a day. In the 1910s, Underwood & Underwood shifted to news photography, reducing stereograph production. They ceased stereograph production in 1920 and sold their stock to the Keystone View Company. In the 1920s, they took pioneering aerial photographs of Miami, but the company ceased operations in the 1940s. Today, early stereoviews can be appreciated through modern 3D technology, such as anaglyph 3D, where colored glasses create a stereoscopic effect.
