Input: John von Neumann
Herman Goldstine wrote: "One of his remarkable abilities was his power of absolute recall. As far as I could tell, von Neumann was able on once reading a book or article to quote it back verbatim; moreover, he could do it years later without hesitation. He could also translate it at no diminution in speed from its original language into English. On one occasion I tested his ability by asking him to tell me how A Tale of Two Cities started. Whereupon, without any pause, he immediately began to recite the first chapter and continued until asked to stop after about ten or fifteen minutes." Ulam noted that von Neumann's way of thinking might not be visual, but more of an aural one.

Could von Neumann recall written text much later?
Output: he immediately began to recite the first chapter and continued until asked to stop after about ten or fifteen minutes.

Input: Freemasonry
The denomination with the longest history of objection to Freemasonry is the Roman Catholic Church. The objections raised by the Roman Catholic Church are based on the allegation that Masonry teaches a naturalistic deistic religion which is in conflict with Church doctrine. A number of Papal pronouncements have been issued against Freemasonry. The first was Pope Clement XII's In eminenti apostolatus, 28 April 1738; the most recent was Pope Leo XIII's Ab apostolici, 15 October 1890. The 1917 Code of Canon Law explicitly declared that joining Freemasonry entailed automatic excommunication, and banned books favouring Freemasonry.

When was the first Papal prounouncement against Freemasonry made?
Output: 28 April 1738
