In 1872, Waynman Dixon found part of an ancient wooden ruler in the North Star Shaft of the Queen's Chamber of the Great Pyramid and gave it to Grant Bey, a Scottish doctor living in Cairo. 13 years ago, with the help of a librarian from the USA, I managed to find this artifact at the Aberdeen Museum in Scotland. (Grant Bey's granddaughter gave it to the museum in 1940, but as is customary for such things, it was forgotten.) They promised to find it in the museum, but then the trail disappeared. In August 2015, Jordan Birch tried to inform about the result of the search in the museum. He received this response from Dr. Neil Curtis, museum curator:

Thank you for your request. Unfortunately, this specimen is not in the museum collection. We have a record that it was acquired in the 40s of the last century, but no later records are kept about it. We will keep in mind his search for work in the museum's warehouse, because we assume that it may be incorrectly established (for example, with material from another part of the world). I am sorry that my report is not positive and I assure you that in the event of a re-finding, the museum will announce this fact publicly.

Regards
Neil Curtis
The curator of the museum

In 2002, Zahi Hawass and the National Geographic Society acquired most of the same old wooden ruler that remained in the shaft. No one has heard of her since.

As this piece of wood is the only artefact from the Great Pyramid, the age of which can be determined by the carbon method, it has incalculable scientific and historical value.
