Dorothy Bush Koch, otherwise known as "Doro", daughter of George H.W. Bush, wrote a book in 2006 titled My Father, My President: A Personal Account of the Life of George H.W. Bush. (You can buy one on Amazon.com for one cent, while supplies last!) The 608 page book is favorable, of course, and gives many personal anecdotes about Bush senior and the Bush family; including the fact that the elder Bush likes to use e-mail to keep in touch with family members, and how they were allowed to take a special flight home after initially being grounded on 9/11/01. I had the opportunity to perouse the book recently and found an interesting tidbit in the photos section. Doro lists the caption as "June 11, 1962: My grandfather Senator Prescott Bush, former secretary of state Dean Acheson, and President John F.Kennedy all receive honorary dsgrees from Yale University" ....Prescott Bush, like his sons and grandsons, was a zealous proponent of population control,. He was charged under the trading with the enemies act in 1942 and had his assets seized. Seventeen months and eleven days later after appearing onstage with Bush, Kennedy was dead. Of course anyone who has even superficially researched the JFK assassination knows that an FBI memo and photo link Bush Sr to JFK Dallas murder scene. (Here is a page on the Nixon-Bush Connection To The Kennedy Assassination). Daddy Bush, (George H. W. Bush) even attacked JFK "Conspiracy Theorists" at Gerald Ford's funeral.
Prescott Bush died October 8, 1972. Kennedy and Bush Sharing a stage may be largely inconsequential, but is nevertheless an interesting footnote of history that has been seldom mentioned (article is here http://www.examiner.com/x-27692-LA-County-Libertarian-Examiner~y2010m7d27-When-John-F-Kennedy-and-Prescott-Bush-appeared-on-stage-together?cid=exrss-LA-County-Libertarian-Examiner
