Albert O. Clark

Albert Oscar Clark (1858–1935), commonly known as A.O. Clark, was an American architect who worked in Arkansas in the early 1900s.

He was born in Medina, New York. He "had established himself as a partner of the firm Mathews and Clark in St. Louis, Missouri, as of 1882, at the relatively young age of twenty-three", and worked there for 23 years in total.

He came from St. Louis, Missouri to Rogers, Arkansas in 1904, to open a second office of the firm, and remained there for the rest of his life. He is mostly known for his designs of "imposing" Benton County public buildings, commercial buildings, and churches, but also designed houses.

He utilized Classic Revival style when designing the Applegate Drugstore (1906) and Bank of Rogers Building. After his work found approval, Clark was hired to build many buildings in Bentonville, Arkansas including the Benton County Jail and the Benton County Courthouse (1928).

A number of his works are listed on the U.S. National Register of Historic Places.
