In 1931, Keady began attending
Washington University in St. Louis Law School on a scholarship. In 1935, he married his high school sweetheart, Dorothy Thompson. A year after getting married, they moved to Greensville, where Keady accepted a job as clerk in the firm of Percy and Farish. In 1937, he and his wife had a son, William Keady Jr. A few years later, in 1941, their daughter Peggy Anne was born. Though Keady went through phases of politics, he eventually chose to focus his legal career on becoming a federal judge. In 1940, voters in
Washington County, Mississippi, elected him as a
state representative. In 1944, they elected him as a
state senator. Keady served as a
delegate at the 1940, 1944, and 1960
Democratic National Conventions, but decided to take a step back from state legislature to focus on his legal practice. Keady considered himself a
traditionalist when it came to politics and race; however, he believed that
racial integration was inevitable and should be accepted. He struggled with his position as judge sometimes, saying, “I am not a crusader, it was never my intention to strike dramatic reforms but to advocate
gradualism." The types of issues that came to his court included
voting rights,
school desegregation, racial and sexual bias in jury selection, etc. A local attorney said, “He was someone the minorities in this state could turn to and know that the
Constitution was alive and well." ==Federal judicial service==
