Bernard H. Siegan (1924-2006) was a preeminent defender of property rights and economic liberty. He received his JD degree from the University of Chicago in 1949 and for more than 20 years practiced law in his native Chicago. During that time he published Land Use Without Zoning (Lexington Books, 1972) which began to transform how Americans think about land use regulation. A year after that book's release, Siegan joined the faculty of the University of San Diego. For the last three decades of his life he was Distinguished Professor of Law at the University of San Diego and specialized in constitutional law.
