George William Foster (born October 7, 1955) is an American businessman and physicist serving as the U.S. representative for Illinois's 11th congressional district since 2013.

[4] After completing his Ph.D., Foster moved to the Fox Valley with his family to pursue a career in high-energy (particle) physics at Fermilab, a Department of Energy National Laboratory.

[7] He was a member of the team that received the 1989 Bruno Rossi Prize for cosmic ray physics for the discovery of the neutrino burst from the supernova SN 1987A.

[8] He and Stephen D. Holmes received the Robert R. Wilson Prize for Achievement in the Physics of Particle Accelerators in 2022 for "leadership in developing the modern accelerator complex at Fermilab, enabling the success of the Tevatron program that supports rich programs in neutrino and precision physics.

"[9] On November 26, 2007, former House Republican Speaker J. Dennis Hastert resigned as the Representative from Illinois's 14th congressional district.

[10] In the March special election, Foster defeated Republican nominee and Hastert-endorsed candidate Jim Oberweis, 53%–47%.

[23] In the general election, he defeated the Republican nominee, State Representative Darlene Senger, with 53.5% of the vote to her 46.5%.

Although it was initially thought that Foster would not be sworn in until April 2008 due to the need to count absentee ballots before his first election was certified, he took the oath of office on March 11, 2008.

[27] Foster joined Vern Ehlers and Rush Holt Jr. as the only research physicists ever elected to Congress.

During a debate with his opponent in the 2012 election, Foster said, "The tax cuts were promised to generate job growth, but did not.

If you follow the money, when you give a dollar to a very wealthy person, they won't typically put it back into the local economy."

He also voted for the Dodd-Frank Wall Street Reform and Consumer Protection Act, with all ten of the amendments he proposed being added to the final bill.

[40] He voted against the American Clean Energy and Security Act, which would create a Cap and trade system.

A Civil War cannon is frankly much less dangerous than weapons we are allowed to carry on the streets in many of the states and cities in our country today.

[20] When Bill and Ann Foster divorced in the mid-nineties, they remained on good terms and agreed to live within blocks of each other.
