Professor George Bush was the first cousin of the president's great-great-great-grandfather, and the author of a book critical of Islam’s founder.
“The Life of Mohammed” went out of print a century ago, and there it was expected to remain, in perpetuity. But in the early 21st century, it was reissued by a tiny publisher simply because of the historical rhyme that a man with the same name occupied the White House. The first George Bush never witnessed the Second Coming, but now his book was enjoying an unexpected afterlife.
Predictably, it enraged some readers in the Middle East, where rage is an abundant commodity. In 2004, Egyptian censors at Cairo’s Al-Azhar Islamic Research Academy denounced the book by President Bush’s “grandfather” as a slander on the prophet, and the State Department was forced to issue a document clarifying the family relationship.
