His relatively modest best from 1979 (10.67 s) improved to a world-class 10.21 the next year.
Additionally, he was named Athlete of the Year by Track and Field News.
From 1981 until 1992, Lewis topped the 100 m ranking six times (seven if Ben Johnson's 1987 top ranking is ignored), and ranked no lower than third.
Lewis said he should have been credited with that jump, claiming the track officials misinterpreted the rules on fouls.
He repeated his number one ranking in the 100 m and long jump, and ranked number six in the 200 m.
The International Association of Athletics Federations (IAAF), the governing body of track and field, organized the first World Championships in 1983.
