James (Jim) Lorenzen

Background

James Lorenzen was born in 1922 in Wisconsin and worked as an electroengineer at Kitt Peak Observatory. His wife, Coral Lorenzen, had a personal UFO encounter in the early 1940s that sparked both their interests in the phenomenon. When the UFO reports surged following Kenneth Arnold's 1947 sighting and the Roswell incident, the Lorenzens decided to create a structured, scientific approach to investigating the claims.

Founding APRO

In January 1952, Jim and Coral founded the Aerial Phenomena Research Organization (APRO) in Sturgeon Bay, Wisconsin, with the explicit goal "to conduct investigations and research into the phenomenon of unidentified flying objects (UFOs) and to find a scientifically acceptable solution to this phenomenon." APRO was a pioneering venture: it was the first UFO research organization to establish a formal scientific advisory board, recruiting consulting Ph.D. scientists in physics, biology, and psychology. This approach distinguished APRO from earlier flying saucer clubs and positioned it as a genuinely scientific enterprise.

As APRO grew, the organization moved to Los Angeles (1954), Alamogordo, New Mexico (1954), and ultimately to Tucson, Arizona (1960), where it remained headquartered. Under Jim's direction, APRO became the first UFO organization to maintain a worldwide network of investigators and field representatives, establishing chapters and contacts in most foreign countries and coordinating reports globally.

Methodology and Legacy

APRO's strength lay in its systematic documentation and scientific rigor. While other organizations like NICAP also pursued serious research, APRO distinguished itself by stressing field investigations, standardized case reporting, and peer review by credentialed scientists. The organization published the influential APRO Bulletin, which chronicled major sightings and investigations from 1952 onward. Membership peaked in 1967 at approximately 1,500 members.

Jim Lorenzen authored UFOs Over The Americas and co-authored UFO: The Whole Story with Coral, documenting investigations spanning hemispheric incidents and patterns. After Jim's death in 1986, Coral continued leading APRO until her death in 1988. The organization was disbanded shortly thereafter, but its legacy endured: APRO's archives constitute the largest civilian historical UFO case file collection in the United States, possibly in the world. Notably, several APRO members founded what became the Mutual UFO Network (MUFON) in 1969, which continues active investigations today.
