I want to know the answer to the following question:
Who was the head of the American Battle Monuments Commission during this period?
All the background I'm provided with is that "He was assigned to the American Battle Monuments Commission directed by General Pershing, and with the help of his brother Milton Eisenhower, then a journalist at the Agriculture Department, he produced a guide to American battlefields in Europe.". Is that enough to answer the question?
Answer: yes
