Marc Benioff, the Salesforce boss well known for his philanthropy in the Bay Area, took a swipe George Lucas the other day — tweeting out “no way” to a Treasure Island museum of the film mogul’s collection of Hollywood memorabilia and narrative art unless he “does something for SF Schools, Hospitals, & Homeless.”

The tweet got the attention of Lucas and his wife, TV financial analyst Mellody Hobson. She phoned Benioff on Tuesday to discuss his concerns.

“Look, I support the museum,” Benioff told us. “But I just would like to see that if we do deals like the museum, we do deals that support our kids.

He added, ”There is a lot of money flowing through San Francisco today, and it would be nice if we saw a percentage of that go into the safety net.”

Benioff’s stand is interesting, considering he was among a host of heavyweights who signed a letter urging the Presidio Trust to allow Lucas to build his museum near Crissy Field a couple of years back.

And in fact, Lucas has done his own share of charitable giving — most notably, pledging in 2012 to donate to educational charities the majority of the $4 billion he made from selling Lucasfilm to Disney.

Also, the $700 million or so that Lucas is committing to his new museum includes a major educational component, teaching kids about digital arts.

Nonetheless, Benioff told Hobson she can count on him to ring her up for money to support the city’s public schools in the future.

As for whether Benioff got any clues from Hobson about how serious Lucas is about abandoning his stalled plan for a museum in Chicago in favor of Treasure Island?

“They want to get their museum built for sure — and I think they are at a point where they will take it wherever they can get it,” Benioff said.
