McWhorter was born and raised in Philadelphia. He attended Friends Select School in Philadelphia, and after tenth grade was accepted to Simon's Rock College, where he earned an A.A. degree. Later, he attended Rutgers University and received a B.A. in French in 1985. He received a master's degree in American Studies from New York University and a Ph.D. in linguistics in 1993 from Stanford University. After graduation he was an associate professor of linguistics at Cornell University from 1993 to 1995 before taking up a position as associate professor of linguistics at the University of California, Berkeley, from 1995 until 2003. He left that position to become a Senior Fellow at the Manhattan Institute, a conservative think tank, and a columnist for the New York Sun. Since 2008, he has been a lecturer at Columbia University.

He has published a number of books on linguistics and on race relations and makes regular public radio and television appearances on related subjects. He has spoken many times on National Public Radio and is an occasional contributor on Bloggingheads.tv. He has appeared twice on Penn & Teller: Bullshit!, once in the profanity episode in his capacity as a linguistics professor, and again in the slavery reparations episode for his political views and knowledge of race relations. He is also the author of the courses titled "Understanding Linguistics: The Science of Language" and "Story of Human Language" for The Teaching Company. His 2003 Authentically Black has been interview-reviewed on booknotes.org.

One of the most accessible American linguists, John McWhorter ranks among the most outspoken scholars in our nation today. A tenured professor specializing in creole languages at the University of California, Berkeley, McWhorter was described in the National Review as "an incisive critic of racial groupthink." The professor and author has found himself at the center of many a controversy. Whether the issue is affirmative action, Ebonics, or the performance of African-American schoolchildren, McWhorter has resisted easy political definition. At a time when race relations is still a hot-button topic, McWhorter has offered insightful commentary on the subject.

John Hamilton McWhorter V was born in 1965 in Philadelphia, Pennsylvania. The son of a professor of social work and a university administrator, McWhorter grew up in West Mount Airy, a racially-mixed neighborhood. One of his first clear memories of those childhood years dates back to 1968, when a group of black kids from the neighborhood surrounded him on the playground and asked him to spell concrete. When he managed to spell it correctly, his "reward" was a sound smacking at the hands of one of his interrogators, as well as frequent taunting thereafter. Unusually intelligent children often feel out of place, but these feelings were an even greater burden to bear for a young black kid being ridiculed by his peers.

When he was four years old, McWhorter experienced his first encounter with a language not his own. After meeting a young girl who spoke Hebrew, the budding language expert began to teach himself the foreign tongue by sounding it out. Furthermore, the self-proclaimed "nerd" described his early sense of intellectual prowess to Cathy Young and Michael Lynch in an interview published in Reason: "When I was five years old ... I thought I was smarter than my teachers--my white teachers--and I would tell them so."

Undeterred by the neighborhood children and their mockery, McWhorter pursued his favored pastimes with a passion. In addition to his longtime love of foreign languages--he would later become proficient or fluent in nine of them--McWhorter was a born film buff. "I love old movies," he told Black Issues in Higher Education. "The Black ones are nice, but what really hooked me was Fred and Ginger." In addition, McWhorter said, "I have loved dinosaurs since I was a child. There's nothing Black about that." Even as a youngster, John McWhorter was able to look beyond color lines, an ability that would eventually help shape his political and linguistic theories.

McWhorter began his climb to the top of the academic ladder at Simon's Rock, a special early college program for teenage scholars of exceptional skill and resolve. After graduating from the Massachusetts school with distinction, McWhorter traveled down the coast to attend Rutgers University in New Jersey, where he majored in French and Romance Languages and graduated with high honors in 1985. At this point in his education, McWhorter's interest in cultural history encompassed not only language but also music. His subsequent graduate work at New York University, where he studied American civilization, resulted in a highly ambitious 1987 thesis entitled: "Scott Joplin and the Operatic Form in Pre-World War I America." Finding a way to merge his various scholarly interests in a coherent and compelling manner, McWhorter was en route to a celebrated career as one of the newest Renaissance Men on the U.S. academic scene. He then moved from New York City to California, earning his doctoral degree in linguistics at Stanford University in 1993.

The next period of McWhorter's blossoming career was a time of transition. Seeking an institution he could call his own, the Stanford graduate spent the 1993-94 academic year at Berkeley in a postdoctoral position. The following year, McWhorter became an assistant professor at Cornell University, but this final East Coast experience was brief and ultimately less than compelling. Soon enough, the promising young scholar decided to make a name for himself in the Golden State, and Berkeley welcomed him back in the fall of 1995.

His work at the University of California, which has made him one of the most dynamic linguistics professors in the nation, started out focusing primarily on pidgin and creole languages. According to the Linguistics Department homepage, in 1992 McWhorter did field work on "the Suriname creole Saramaccan." McWhorter has developed a number of linguistic theories, including the Creole Prototype Hypothesis, which delves into the nature of modern creoles, and the Afrogenesis Theory, which deals with the West African origins of plantation creoles. McWhorter became a tenured professor at Berkeley in 1999.

McWhorter has successfully navigated the boundaries between intellectualism and mainstream commentary. As he wrote in a Wall Street Journal article: "Though I relish my vocation, I'm troubled by its hermetic nature. Most academic work is ... consulted only by the occasional student or professor. So ... I've tossed my hat into the public fray--writing books and newspaper articles for lay readers."

But while McWhorter has sought to balance "hermetic" scholarship with popular critiques, he clearly understands his responsibility as an academic. The scholar has appeared on Good Morning America, The Today Show, Dateline NBC, and BBC World News, in addition to making a remarkable number of radio appearances. While some might find the temptation to sacrifice intellectual ambition in exchange for celebrity status too great, McWhorter, as the author or editor of seven books and dozens of articles on linguistics, remained aware that fame is no substitute for the pure pleasure of intellectual exploration for its own sake. He noted in the Wall Street Journal, "I don't write as many linguistics articles as I used to.... My academic career impinges on my public one: I turn down requests to write and speak in favor of maintaining my scholarly outlook."
