The medal commemorates the 100th anniversary of the American Society of Mechanical Engineers (ASME). ASME was founded in 1880 by Alexander Lyman Holley, Henry Rossiter Worthington, John Edison Sweet and Matthias N. Forney in response to numerous steam boiler pressure vessel failures. Known for setting codes and standards for mechanical devices, ASME conducts one of the world's largest technical publishing operations, holds numerous technical conferences and hundreds of professional development courses each year, and sponsors numerous outreach and educational programs.

The medal measures 64mm in diameter and was struck in nickel silver by the Medallic Art Company of Danbury, Connecticut.
