In his Flying Wings & Radical Things, Tony Chong writes the N-156 (T-38 / F-5) was drawn by Joe Talley and George Gluyas. Schmued and Gasich had several angry confrontations over the N-156, with Gasich (Northrop's Chief of Preliminary Design) advocating embedding the engines in the fuselage to attain supersonic performance. Eventually, Schmued (Vice President of Engineering) relented.

Tony Chong writes the N-156 'was very much a Schmued-influenced design', he doesn't mention Lee Begin. Leon Begin is mentioned as an important member of the T-38 / F-5 design team here:
