[1][2] He received a Bachelor of Science degree in aeronautical engineering from Louisiana State University (LSU) in 1939, and worked for Glenn L. Martin Company in Baltimore, Maryland.

He assembled a team which moved from NACA's Langley Memorial Aeronautical Laboratory in Hampton, Virginia, to the Muroc Army Air Base in California's Mojave Desert.

[4] He was involved in the testing of the X-1, the aircraft in which United States Air Force (USAF) Captain Chuck Yeager carried out the first piloted supersonic flight at Muroc on October 14, 1947.
