Who was the first flight test engineer? The discipline of Flight Test Engineering has existed since at least 1903, but when did engineers identify their work, distinguish their work from other disciplines, under terms that would mark it as Flight Test Engineering?

This may take the form of someone who first used the term flight test engineer or flight test engineering.  

Google demonstrates a history of the terms:

NATO describes the history of its flight test organization this way:


  Soon after its founding in 1952, the Advisory Group for Aerospace
  Research and Development (AGARD) recognized the need for a
  comprehensive publication on flight test techniques and the associated
  instrumentation. Under the direction of the Flight Test Panel (now the
  Flight Vehicle Integration Panel) a Flight Test Manual was published
  in the years 1954 to 1956. This original Manual was prepared as four
  volumes: 1. Performance, 2. Stability and Control, 3. Instrumentation
  Catalog, and 4. Instrumentation Systems. As a result of the advances
  in the field of flight test instrumentation, the Flight Test
  Instrumentation Group was formed in 1968 to update Volumes 3 and 4 of
  the Flight Test Manual by publication of the Flight Test
  Instrumentation Series, AGARDograph 160. In its published volumes
  AGARDograph 160 has covered recent developments in flight test
  instrumentation.
The Michigan Alumnus written on Aug 13, 1938 refers to Clarence Johnson's experiences as a  Flight Test Engineer. He graduated with a MS in 1933 so presumably became an engineer at that time.
