Obama became conscious of racism and what it meant to be African-American. He later described how he struggled to reconcile social perceptions of his multiracial heritage with his own sense of self: "I noticed that there was nobody like me in the Sears, Roebuck Christmas catalog. . .and that Santa was a white man," he wrote. "I went into the bathroom and stood in front of the mirror with all my senses and limbs seemingly intact, looking as I had always looked, and wondered if something was wrong with me.
After high school, Obama studied at Occidental College in Los Angeles for two years. He then transferred to Columbia University in New York City, graduating in 1983 with a degree in political science. After working in the business sector for two years, Obama moved to Chicago in 1985. There, he worked on the impoverished South Side as a community organizer for low-income residents in the Roseland and the Altgeld Gardens communities.
It was during this time that Obama, who said he "was not raised in a religious household," joined the Trinity United Church of Christ. He also visited relatives in Kenya, and paid an emotional visit to the graves of his biological father and paternal grandfather. "For a long time I sat between the two graves and wept," Obama wrote. "I saw that my life in America—the black life, the white life, the sense of abandonment I'd felt as a boy, the frustration
and hope I'd witnessed in Chicago—all of it was connected with this small plot of earth an ocean away."
Returning from Kenya with a sense of renewal, Obama entered Harvard Law School in 1988. The next year, he joined the Chicago law firm of Sidley Austin as a summer associate and Michelle Robinson, a young lawyer assigned to be Obama's adviser. Not long after, the couple began dating. In February 1990, Obama was elected the first African-American editor of the Harvard Law Review. He graduated magna cum laude from Harvard in 1991.
