Gilman, Walter

A native of Haverhill, Massachusetts with a burning passion for mathematics and the occult.  A workaholic student, he astonished his teachers at Miskatonic University with his bizarre notions.  His studies led him to believe that Keziah Mason, a witch of the seventeenth century, may have known more than the great scientists of today.  But his contact with her through the bizarrely shaped room in her old house led him on a trip through the horrors of the universe.
