PHOENIX — Six years before a valuable Willem de Kooning painting was stolen in 1985, the director of the University of Arizona Museum of Art warned that security needed to be beefed up at the small museum.

But university administrators, who have since retired, didn’t act on those warnings, according to memos obtained by The Arizona Republic, a part of the USA TODAY Network, as part of a public-records request. 

Museum officials on May 8, 1979, requested that additional police officers be assigned to the building, cautioning that:

“The museum’s good fortune in avoiding major theft or vandalism so far is strictly a matter of luck,” the memo said. “As the art museum becomes better known, this luck will quickly dissipate.”

“Woman-Ochre” is now back at the museum after being discovered in a New Mexico estate sale in 2017.  And the university is once again faced with safeguarding a treasure even more famous and more valuable than when it was stolen.

In the years the painting went missing, works by the Dutch-American artist de Kooning exploded in value.  University officials are no longer publicly releasing a value, though as recently as 2015 “Woman-Ochre” was valued at up to $160 million. 

Behind the mysteries:This is the saga of Arizona’s famous stolen Willem de Kooning painting

The 1979 memo which was copied to then-UA President John Paul Schaefer, requested that two members of the campus security force be on duty during operating hours as a “minimal ounce of prevention.” 

But when the de Kooning painting was stolen in 1985, it was common to have only one University of Arizona police officer on duty at the museum, according to subsequent memos. 

When the theft occurred, it was the day after Thanksgiving and only one campus security officer was present at the museum. Two student workers were on duty. But no staffer was in the second-floor gallery when “Woman-Ochre,” was cut from its wooden frame. Like many small museums at the time, there was no video-camera system to capture the theft.
