The Mayan Shard Caper (Signed First Edition)

John Keshishian is an academic surgeon, now semi-retired. He has been a professor of surgery, chief of his division, and chief of his medical staff.

Over a span of fifty years, he has been involved in research, teaching, photography, writing, and archaeology and served as consultant to many organizations including the National Geographic Society, NASA, FAA, Department of State, US Air Force, Veterans Affairs, and the FDA. He served as a board member of CARE, MEDICO and the Medlantic Health Care Group. He also served as medical director of a small airline.

He has appeared on the VOA, sending broadcasts abroad in his native tongue, Armenian, as well as numerous radio and television appearances, both as guest and moderator. He was sometimes known, on those occasions, as Jack Cartwright.

Taught to fly by French pilots in Vietnam, he completed his flight training under the FAA's aegis at Woodbridge Airport in Virginia and holds a Commercial Pilot rating.

His idea for this story came from a combination of observations at various Mayan ruin sites deep in Guatemala's jungles and the discovery of the mysterious Mojarra stone, which became an object of controversy. At the request of Dr. George Stuart, he made a rubbing of that stone in the museum in Jalapa, Mexico. A rendition of that rubbing appears in Stuart’s report of the Mojarra stone in a publication of Stuart’s Research Center.
