NEWTON, Mass. — In the past four months, Myra Kraft had a near constant companion, her husband Robert.

Busy with his active role in the NFL labor negotiations, the owner of the New England Patriots knew what mattered most.

“There was no greater bond anywhere than the bond between her and my dad,” Josh Kraft, one of their four sons, said at her funeral service on Friday. “If we took all the hours in those four months, they were together for 90 percent of those hours.

“And dad would be rubbing her feet, holding her hand, putting his head on her lap. And she’d be patting his head, telling each other how much they loved each other.”

Myra Hiatt Kraft died of cancer on Wednesday at the age of 68, about a month after their 48th anniversary.

The 80-minute service at Temple Emanuel drew about 1,500 people — including those from the worlds of football and philanthropy — on a sunny day with the temperature in the 90s.

NFL commissioner Roger Goodell and NFL Players Association chief DeMaurice Smith were there as player representatives elsewhere were reviewing terms of a tentative agreement that owners approved overwhelmingly on Thursday in Atlanta.

“There was never any doubt” that he would attend, Goodell said. “She just meant so much to all of us. She just made the world a better place.”

She managed the Robert and Myra Kraft Family Foundation and was president of the New England Patriots Charitable Foundation, which contributed millions of dollars to charities in the United States and Israel. From 1995-2002 she was the first woman to chair the Boys & Girls Clubs of Boston.

She had the resources. Her husband was listed by Forbes magazine in March as the 304th richest billionaire in the United States.

“Myra didn’t only write checks,” Rabbi Wes Gardenswartz said at the service. “All the pictures that we see of her show her in the trenches, serving food in the kitchens, packing the bags full of clothes that are going to be donated. In the trenches, doing real work with real people.”

She also served as chairwoman of the Combined Jewish Philanthropies and was on the board of directors of the American Repertory Theatre, Brigham and Women’s Hospital, the Boys and Girls Clubs of Boston, and Brandeis University, where she graduated in 1964.
