The Hunt's originator was Dr. Robert Hunter, a long-time history teacher at Carlmont High School in Belmont, CA. In 1969, Dr. Hunter initiated the Hunt as both a whimsical and competitive exercise to improve students' research skills. Dr. Hunter shepherded the Hunt through its first 40 years, and remained an active advisor for it until his passing in 2012.
From 2009-2014, Dave Lowell, a math teacher at Castilleja High School in Palo Alto, CA, took over as Hunt Director.
