Bill Foster is an American businessman, physicist, and politician currently serving as the U.S. Representative for Illinois's 11th congressional district. A member of the Democratic Party, Foster has been in office since 2013, following a previous term representing Illinois's 14th congressional district from 2008 to 2011. His extensive background in physics and business informs his legislative priorities and committee work in Congress.
Early life and career
Bill Foster was born on October 7, 1955, in Madison, Wisconsin. He completed his secondary education at James Madison Memorial High School before pursuing higher education. Foster earned a Bachelor of Science degree in physics from the University of Wisconsin–Madison in 1976. He continued his academic journey at Harvard University, where he obtained a Ph.D. in physics in 1983. His doctoral dissertation focused on experimental limits regarding proton decay, a significant topic in particle physics.
At the age of 19, Foster co-founded a company with his younger brother, Fred, named Electronic Theatre Controls. This enterprise specializes in manufacturing theatrical lighting fixtures and control systems, contributing to the entertainment industry. Following the completion of his doctoral studies, Foster relocated to the Fox Valley area in Illinois to work at Fermilab, a prominent Department of Energy National Laboratory. Over a span of 22 years at Fermilab, he engaged in various high-energy physics projects, including the design of equipment and data analysis software for the Collider Detector at Fermilab (CDF), which played a crucial role in the discovery of the top quark. Additionally, he managed the design and construction of the Anti-Proton Recycler Ring, a significant component of the laboratory's Main Injector.
Foster's contributions to the field of physics have been recognized through numerous accolades. In 1998, he was elected as a fellow of the American Physical Society. He was part of a team awarded the Bruno Rossi Prize in 1989 for their work in cosmic ray physics, particularly for the discovery of a neutrino burst from the supernova SN 1987A. His achievements also include receiving the Particle Accelerator Technology Prize from the Institute of Electrical and Electronics Engineers and an Energy Conservation award from the U.S. Department of Energy for his innovative applications of permanent magnets in particle accelerators. In 2022, he and a colleague received the Robert R. Wilson Prize for their leadership in developing Fermilab's modern accelerator complex.
House tenure
Foster's political career began when he announced his candidacy for the U.S. House of Representatives in response to the resignation of former House Republican Speaker J. Dennis Hastert from Illinois's 14th congressional district. He entered the race on May 30, 2007, and won a special election held in March 2008, defeating Republican candidate Jim Oberweis. Foster's victory marked the beginning of his congressional career, and he was sworn into office on March 11, 2008.
During his first full term in the House, Foster faced challenges from various candidates. In the November 2008 general election, he successfully defeated Oberweis again, securing a significant majority of the vote. However, in the 2010 election, Foster lost his seat to Republican Randy Hultgren. Following this defeat, Foster shifted his focus to the 11th congressional district, where he successfully ran for office in 2012. Since then, he has been re-elected multiple times, consistently winning a majority of the votes in subsequent elections.
Foster's tenure has been characterized by his commitment to representing the interests of his constituents in Illinois. He has participated in various electoral campaigns, often running unopposed in Democratic primaries and facing Republican challengers in the general elections. His electoral success reflects his ability to connect with voters and address their concerns.

Throughout his time in Congress, Foster has focused on a range of legislative issues, leveraging his background in science and technology. He has served on the Committee on Financial Services, where he has been involved in discussions surrounding economic policies, financial regulations, and technological advancements in the financial sector. Within this committee, he holds positions on several subcommittees, including the Subcommittee on Digital Assets, Financial Technology, and Artificial Intelligence, as well as the Subcommittee on Financial Institutions, where he serves as the ranking member. Additionally, he is a member of the Subcommittee on National Security.
Foster's legislative priorities often reflect his scientific expertise, particularly in areas related to technology and innovation. His work on the Financial Services Committee allows him to address the intersection of technology and finance, advocating for policies that promote responsible innovation while ensuring consumer protection and financial stability.
In terms of fundraising, Foster has received significant support from labor-related political action committees, which have contributed to his electoral campaigns. His fundraising efforts have included donations from various political action committees, demonstrating his ability to garner financial backing for his initiatives.
As of now, Foster continues to serve in the U.S. House of Representatives, with his current term set to conclude on January 3, 2027.
