Re: General Douglas McArthur [sic] and At age 30, he became the youngest Chief of Staff of the U.S. Army.

You spelling in the title is incorrect ( MacArthur not McArthur) and the above fact from your source (http://archive.constantcontact.com/fs155/1108762609255/archive/1116360892946.html) is flat wrong for if it where true, Doug (Born 1880) would have been Chief of Staff in 1910 only seven years after he left West Point in the Class of 1903.

The truth is he became Chief of Staff in 1930 at age 50.

It’s probably a mere typo, wrote 30 instead of 50. Given the usual age of top generals I’d say 50 probably did make him the youngest Army COS.
