Caveat AARO DOES NOT USE THE WORD "FIRST" OR THE WORD "DIRECTOR" HERE. It says Blue Book "was led successively by" five officers and lists Ruppelt at the head of that list, having previously directed the reorganised Project GRUDGE. First in a list of successive leaders is what the page supports.

Caveat BY HIS OWN ACCOUNT - the report says so and this claim keeps it. What Ruppelt did next is on printed 16 and cuts both ways: he created an "unknown" category so that cases were not forced to an answer, and he said staff who were "too pro or too con" would be let go. This map also carries him as Project Blue Book's first director, which printed 18 confirms in the same breath as calling him "the former Director of the reorganized Project GRUDGE".
