Williams was born in 1892. His father was in the hardware business and, according to Williams, the demand for tents in Caddo, Oklahoma where he grew up at the turn of the century was such that they were purchased before they had even been unloaded from wagons. James Williams was reported in Oklahoma City, working as a delivery driver in 1910, but returned to Caddo in 1911. He married Daisy Lane in Caddo in 1913. The couple had three children. Soon after marriage, they moved to Durant, Oklahoma and opened a furniture store. They moved to Ardmore, Oklahoma in 1922, where he opened some unspecified business, but soon returned again to Caddo.
Political career
Williams used a humorous postcard in opposition to President Dwight D. Eisenhower in his campaign for lieutenant governor, a gimmick that the post office stopped. He also legally changed his name from Simeon Pinckney Williams to Cowboy Pink Williams. He won the run-off to get the Democratic nomination, defeating incumbent James Berry. Williams ran for Lieutenant Governor of Oklahoma in 1954. He finished second in the Democratic primary with 78,981 votes, behind incumbent five-term Lieutenant Governor James E. Berry's 148,406 votes. Williams defeated Berry in the runoff by 222,784 votes to 203,747. He defeated Republican Kenneth W. Gray in the general election with 336,311 votes and served from 1955 to 1959. He ran for a second term in 1958 and this time placed first in the Democratic primary with 176,171 votes to State Representative George Nigh's 80,727. Nigh defeated Williams in the runoff with 302,050 votes to 190,530. Williams ran for Oklahoma State Treasurer in 1962, coming first with 165,055 votes and advancing to the runoff with Glen R. Key, who took 105,479 votes. Former Governor Johnston Murray surprisingly finished last in the four-man field with 77,881 votes. Williams won the runoff with 214,055 votes to Key's 210,881 and then won the general election against Republican Tom R. Moore with 331,644 votes. After leaving the state treasurer's office due to term limits, Williams announced an intention to seek office in the United States House of Representatives, but never ran.
Later life
In 1973, when Caddo celebrated its centennial, Williams served as the planning committee chair.
