The Holley Medal is an award of ASME (the American Society of Mechanical Engineers) for "outstanding and unique act(s) of an engineering nature, accomplishing a noteworthy and timely public benefit by one or more individuals for a single achievement, provided the contributions are equal or comparable."[1]
The award was established in 1924 in honor of the American mechanical engineer, inventor and charter member of ASME Alexander Lyman Holley (1832-1888).
