Preparing for the Monday, August 7, 1944, dedication, the Harvard News Office prepared a news release titled "World's Greatest Mathematical Calculator," followed by the bold, unqualified statement that "In charge of the activity . . . is the inventor, Commander Howard H. Aiken, USNR," who "worked out the theory which made the machine possible."
Also a good read: Aug. 7, 1944: Still a Few Bugs in the System, on Wired. I can't find anything closer to the original text, the wikipedia entries on Mark I and Howard Aiken don't reference it.
Update #1: The original text seems to be on enotes.com, but you need to subscribe to access it.
Update #2: Brooks refers to the Harvard News Office press release he read on Time Magazine, as he writes on page 137 of Makin' numbers: Howard Aiken and the computer.
