SAE Standardization History

1905, SAE was established.

First President – Andrew Riker

First VP – Henry Ford

Initial Membership – 30 Engineers

• 1916, expanded to include to include the entire ground based mobility

industry as well as the new field of aeronautics. The name of the

association was changed to Society of Automotive Engineers.

• 1960, SAE transformed into an international organization “SAE

International”

• Today SAE is the largest producer of consensus based ground mobility

standards in the world.
