Philip Julian Klass (November 8, 1919 August 9, 2005) was an American journalist and UFO researcher with a background in electrical engineering. Klass was born in Des Moines, Iowa and died in Merritt Island, Florida. Klass was known for his skepticism regarding UFOs. In the ufological and skeptical communities, Klass tends to inspire strongly polarized appraisals. Klass has been called the "Sherlock Holmes of UFOlogy". In a 1999 interview, fellow debunker Gary Posner wrote that despite some recent health problems, the 80 year-old "Klass''s mind and pen remain razor sharp, to the delight of his grateful followers and to the constant vexation (or worse) of his legions of detractors."
