Pat Delgado

Background & Engineering Career

Pat Delgado (c. 1918–2009) was a retired engineer with significant expertise in space program technology and systems design. His engineering background and analytical mindset would shape his approach to investigating one of the most enigmatic phenomena of the late 20th century: crop circles. Working within Britain's aerospace and defense sectors, Delgado developed the methodological rigor that would characterize his later paranormal research—combining technical documentation, measurement protocols, and systematic field investigation rather than anecdotal reportage.

Pioneering Crop Circle Research (1980s–1990s)

In the 1980s, Delgado emerged as one of the first serious investigators of the crop circle phenomenon, which was gaining widespread attention in southern England. Rather than dismissing the formations as hoaxes or natural curiosities, Delgado treated them as worthy subjects of rigorous examination. His collaboration with electrical engineer Colin Andrews transformed crop circle research from tabloid fodder into a documented investigative discipline later termed "cereology."

Together, Delgado and Andrews conducted field surveys, mapped formations, collected soil and plant samples, interviewed witnesses, and documented physical evidence with scientific precision. Their 1989 bestseller Circular Evidence: A Detailed Investigation of the Flattened Swirled Crops became a landmark text—reportedly selected by the British Royal Family for the Queen's summer reading list. The book sold over 100,000 copies in Europe alone, establishing crop circles as a legitimate subject of paranormal inquiry.

Major Publications & Methodology

Delgado co-authored three major works with Andrews: Circular Evidence (1989), Crop Circles: The Latest Evidence (1990), and Crop Circles: Conclusive Evidence? His approach combined technical measurement, photographic documentation, and pattern analysis to argue that some formations exhibited characteristics inconsistent with conventional mechanical creation. Delgado was meticulous in distinguishing between proven hoaxes, ambiguous cases, and formations he considered genuinely anomalous.

Unlike some paranormal researchers, Delgado remained cautious about drawing definitive conclusions about the phenomenon's origins—whether extraterrestrial, interdimensional, or terrestrial. His work emphasized documenting evidence and raising questions rather than promoting a single explanation, making him a bridge figure between serious investigation and mainstream skepticism.

Legacy & Impact

Delgado's contributions helped establish crop circles as a documented anomaly worthy of systematic investigation, even as scientific consensus remained skeptical. His collaboration with Andrews gave cereology methodological credibility; their books remain reference texts in UFO and paranormal research communities. Though crop circles would later be demonstrated to be primarily human-created (notably the 1991 confession by hoaxers Doug Bower and Dave Chorley), Delgado's insistence on rigorous field documentation set a precedent for paranormal research that persists today. He died in May 2009 at age 90, having witnessed the field he helped pioneer mature and face its limitations.
