Morton J. Horwitz

Morton J. Horwitz is an American legal historian and law professor at Harvard Law School. The recent past dean of Harvard Law School, Elena Kagan, relates that during her time at law school, students often nicknamed him "Mort the Tort" since he taught the first-year subject Torts.

Horwitz obtained an A.B. from the City College of New York, an A.M. and Ph.D. from Harvard University, and an LL.B. from Harvard Law School. He became an associate professor of law at Harvard Law School in 1970 and gained tenure as a full professor in 1974. In 1981, he was appointed the Charles Warren Professor of American Legal History.

His first book, The Transformation of American Law, 1780-1860, was published in 1977 and is widely regarded as one of the most important books in modern American legal historiography. It won the Bancroft Prize, the preeminent prize in American history in the United States. A product of its time, this book sought to give a "thick description" of the transformation of American law in the period without appealing to "covering laws." The book was conceived as an attack on the so-called "Consensus School" of American Legal History, which had dominated the field of Legal History in the 1950s and minimized the role of class dimensions in American legal history. The main argument of his book is that in the first half of the 19th century, many judges self-consciously allied themselves with a rapidly growing class of mercantile capitalists and promoted a series of legal rules which favored those capitalists.
