Fred Severs Clinton (1874–1955) was one of the first medical doctors in Oklahoma, having begun to practice while the area was still part of Indian Territory.

As a financial partner with Dr. J. C. W, Bland, another early physician in the Tulsa area, he helped finance the drilling of the Sue A.

Bland #1, the first oil well in Red Fork, which helped propel Tulsa into the ranks of a major American city in the early 20th century.

He was born near the present city of Okmulgee, Oklahoma, on April 15, 1874, to an early Euro-American migrant, Charles Clinton, and his wife, Louise (née Atkins).

[1][5] In 1897, Fred married Jane Carroll Heard, a native of Elberton, Georgia, who was reported to be an accomplished musician.

When the couple first came to Indian Territory, they could not find any suitable house available in Tulsa, so they moved into the home of her mother-in-law in Red Fork.

He campaigned for improved water and sewer systems, public health facilities and fireproof buildings.
