Robert Huber (7 July 1901 – 7 April 1995) was a Swiss mechanical engineer.
From 1920 to 1924 he studied at the Swiss Federal Institute of Technology (now ETH Zurich) under Professor Aurel Stodola.
In 1924, Huber became Technical Director of the Bureau Technique Pescara where he supervised the design of nearly 30 different sizes and types of free-piston engine and acquired the nickname "Mr Free Piston".
He also heard of a proposal by Petro Shelest for turbines driven by compressed air.
Huber stayed at Bureau Technique Pescara (which became Société d'études mécaniques et énergétiques[3] (SEME) in 1939) until 1962.
