A copy of Barack Obama's biography as of 2001 is in the extended entry, from Harvard (link). Among other things I didn't know was that he also worked as a community organizer in Harlem after graduating from Columbia in 1983. He's also listed as a "senior lecturer at the University of Chicago Law School"; the university's site confirms that designation: "Senior Lecturer in Law" (link). However, if they now say that he was a "professor", so be it.

In addition to the Chicago Annenberg Challenge, the Joyce Foundation, and the Woods Fund of Chicago, they also list three organizations I hadn't hear about before:
* the Center for Neighborhood Technology
* the Chicago Lawyers Committee for Civil Rights Under the Law
* Public Allies.

There's more on the CLCCRUL here; "interesting" cases, including at least one about immigration. On that topic, see this from the bio:

He is the recipient of the 1995 Legal Eagle Award from IVI-IPO for his work in bringing Illinois into compliance with the National Voter Registration Act (Motor-Voter).

Barack H. Obama '91

Barack Obama, D-Chicago, is the Illinois State Senator for the 13th State Senate District representing areas of Chicago's South Side. He earned his A.B. in political science from Columbia University in 1983 and then spent five years working as a community organizer, first in Harlem, then in Chicago. In 1988, he enrolled at Harvard Law School, where he served as the first African-American president of the Harvard Law Review and was a member of the Executive Board of the Black Law Students Association. He earned his J.D., magna cum laude, in 1991.

In 1992, Senator Obama served as Illinois Executive Director of PROJECT VOTE!, an effort that added over 100,000 newly registered voters in Illinois. That year, he also joined Miner, Barnhill and Galland as a civil rights attorney and was elected to the Illinois State Senate. He is currently in his second term as state senator, having been reelected in 1998. His term runs through January 2003. Additionally, Senator Obama still works with the firm Miner, Barnhill and Galland and is also a senior lecturer at the University of Chicago Law School, where he teaches constitutional law.

Senator Obama lost a bid for the Democratic nomination for Rep. Bobby Rush of Illinois' seat in the U.S. House of Representatives earlier this year.

In 1993, Senator Obama was named by Crain's Chicago Business as one of "40 under 40" outstanding young leaders in the City of Chicago. He is the recipient of the 1995 Legal Eagle Award from IVI-IPO for his work in bringing Illinois into compliance with the National Voter Registration Act (Motor-Voter). His commentaries have been heard on National Public Radio and published in his memoir, Dreams From My Father, which was published by Random House in August 1995.

Senator Obama serves on the boards of several organizations including the Chicago Annenberg Challenge, where he is chairman, the Joyce Foundation, the Woods Fund of Chicago, the Center for Neighborhood Technology, the Chicago Lawyers Committee for Civil Rights Under the Law, and Public Allies.

Senator Obama is married to Michelle Obama. They have one daughter, Malia Ann Obama.
