Senator Donald W. Riegle, Jr. of Michigan introduced the joint resolution in July 1983, and it became Public Law 98-238 on March 20, 1984, designating the single week beginning May 6 that year. Ronald Reagan proclaimed that week on May 5, 1984, and every week honored after it required a fresh act of Congress.
The senator from Michigan
Donald W. Riegle, Jr. put the first one in. He introduced Senate Joint Resolution 132 on July 15, 1983, and it moved slowly, passing the Senate by voice vote that November and the House the following March.
The resolution also explains why the week sits where it does. Its preamble notes that "the American Association of Correctional Officers will be holding its annual convention May 6-12, 1984," and Congress designated exactly that week. No later instrument ever made the pattern permanent.
