William Roger Corliss (August 28, 1926 – July 8, 2011) was an American physicist and writer who was known for his interest in collecting data regarding anomalous phenomena (including cryptozoology, out-of-place artifacts and unidentified flying objects). Corliss was Charles Fort's most direct successor. Arthur C. Clarke described Corliss as "Fort's latter-day - and much more scientific - successor."
