Julie Bowen plays TV’s wacky and loving mom Claire Dunphy on the ABC sitcom “Modern Family” and she recently won the Emmy for Best Supporting Actress in a Comedy. A native of Baltimore, she got much of her education in New England, at the private St. George’s School in Middletown, R.I., and then at Brown University, where she majored in the very un-Claire like Italian Renaissance Studies. On ABC, Bowen is the mother of two teenage girls and one boy, but at home it’s three young boys for her and her software-engineer husband. Because her oldest son has a life-threatening allergic reaction (what’s called anaphylaxis), Bowen, when she’s not acting, is advocating for better treatment and more awareness. Food allergies in children have risen by almost 20 percent in the last decade, according to the federal Centers for Disease Control and Prevention, and today they impact 5 percent of all children. On Thursday, as part of Bowen’s campaign, students at Boston Latin will brainstorm ways to help the school community be more aware of life-threatening allergic reactions and judges will choose 15 winners, each of whom will be awarded a $2,000 college scholarship. We talked with Bowen for a few minutes on Monday.
