Carl Caspar Giers[3] (April 28, 1828 – May 24, 1877) was a Kingdom of Prussia-born American photographer active primarily in Nashville, Tennessee, in the mid-19th century.

In documenting Nashville's rapid postwar growth and expansion, he photographed numerous prominent individuals, including political leaders, Civil War generals, and important business and cultural figures.

A popular resident of the city, he served one term in the Tennessee House of Representatives (1874–1875), having been the nominee of both the Democratic and Republican parties.

[4] In January 1855, he opened a daguerreotype studio at the corner of Deaderick and College streets that featured "powerful side and sky lights" and rooms "fitted up in elegant style," and catered to "the ladies particularly.

[12] He was a frequent presence at Nashville German-American festivals and events during this period,[13][14] and was "Worshipful Master" of the Masons' Germania Lodge.

[15] In September 1874, Nashville Democrats nominated Giers for one of Davidson County's four seats in the Tennessee House of Representatives.

[23][24][25] Giers' studio, located at 43-45 Union Street in Nashville, was described by the local newspaper as a "mammoth art gallery" and one of the city's key tourist attractions in the early 1870s.
