The Baumann family was a family of American architects who practiced in Knoxville, Tennessee, and the surrounding region, in the late 19th and early 20th centuries. It included Joseph F. Baumann (1844–1920), his brother, Albert B. Baumann, Sr. (1861–1942), and Albert's son, Albert B. Baumann, Jr. (1897–1952). Buildings designed by the Baumanns include the Mall Building (1875), the Church of the Immaculate Conception (1886), Minvilla (1913), the Andrew Johnson Building (1930), and the Knoxville Post Office (1934).

The Andrew Johnson Building is a high-rise building in downtown Knoxville, Tennessee. Completed in 1929 as the Andrew Johnson Hotel, at 203-foot (62 m), it was Knoxville's tallest building for nearly half a century. In the 1980s, it was converted to office space by Knox County. In 1980, the Andrew Johnson Building was added to the National Register of Historic Places. In 2017, BNA Associates announced plans to convert it back to a hotel. The plans were approved in 2020. As of 2022, the county offices have been almost entirely vacated in preparation for the extensive renovations.
