Clark Blanchard Millikan (August 23, 1903 – January 2, 1966) was a distinguished professor of aeronautics at the California Institute of Technology (Caltech), and a founding member of the National Academy of Engineering.

He attended the University of Chicago Laboratory Schools, graduated from Yale College in 1924, then earned his PhD in physics and mathematics at Caltech in 1928 under Professor Harry Bateman.

[3] His first major engineering work began with the construction of large wind tunnels, particularly the Southern California Cooperative Wind Tunnel in Pasadena, which was shared by five major aircraft companies.

In 1942, Rolf Sabersky worked in mechanical design on the Southern California Cooperative Wind Tunnel under Mark Serrurier and Hap Richards.

[4][5][6] Caltech wind tunnels were subsequently used during the design phase of more than 600 types of aircraft and missiles.
