Steve Jobs's widow attending tonight's US State of the Union address

Jobs will be a guest of First Lady Michelle Obama, the White House confirmed to MarketWatch. Her appearance has fueled speculation that Obama may mention Jobs in his address to the nation tonight.

Among numerous nonprofit activities, Jobs is the founder and chair of the Emerson Collective, which works with entrepreneurs to advance domestic and international social reform efforts. She also serves on the White House Council for Community Solutions.

Jobs is also president of the board at the after-school program College Track, which she founded in 1997. It helps to prepare underprivileged high school students for college.

She also serves on the boards of the directors of the New America Foundation, Teach for America, NewSchools Venture Fund, Stand for Children, and Conservation International.

Jobs met her husband of 20 years when she was a student at Stanford. The Apple co-founder delivered a speech at the Stanford graduate business school in 1989. They had three children together: Eve, Erin and Reed.

Last year, the late Jobs attended a dinner with Obama and other executives from Silicon Valley. Jobs also gave Obama a pre-release iPad 2 before the second-generation tablet went on sale to the public last year.

Obama even issued a public statement last October after Jobs passed away. The U.S. president said he and his wife Michelle were saddened by the loss.

"The world has lost a great visionary," Obama said. "And there may be no greater tribute to Steve's success than the fact that much of the world learned of his passing on a device he invented."
