Carl Menger (February 28, 1840 – February 26, 1921) was the founder of the Austrian School of economics, famous for contributing to the development of the theory of marginal utility, which contested the cost-of-production theories of value, developed by the classical economists such as Adam Smith and David Ricardo.

Menger was born in Nowy Sącz in Austrian Galicia, now in Poland. He was the son of a wealthy family of minor nobility; his father, Anton, was a lawyer. His mother, Caroline, was the daughter of a wealthy Bohemian merchant. He had two brothers, Anton and Max, both prominent as lawyers. After attending Gymnasium he studied law at the Universities of Prague and Vienna and later received a doctorate in jurisprudence from the Jagiellonian University in Kraków. In the 1860s Menger left school and enjoyed a stint as a journalist reporting and analyzing market news, first at the Lemberger Zeitung in Lwów, Ukraine and later at the Wiener Zeitung in Vienna.

During the course of his newspaper work he noticed a discrepancy between what the classical economics he was taught in school said about price determination and what real world market participants believed. In 1867 Menger began a study of political economy which culminated in 1871 with the publication of his Principles of Economics (Grundsätze der Volkswirtschaftslehre), thus becoming the father of the Austrian School of economic thought. It was in this work that he challenged classical cost-based theories of value with his theory of marginality - that price is determined at the margin.

Ronald Ernest "Ron" Paul (born August 20, 1935) is an American politician who has been the U.S. Representative for Texas's 14th congressional district, which includes Galveston, since 1997, and a three-time candidate for President of the United States, as a Libertarian in 1988 and as a Republican in 2008 and currently 2012. He is an outspoken critic of American foreign and monetary policies, including the Military–industrial complex and the Federal Reserve, and is known for his libertarian-leaning views, often differing from his own party on certain issues.

A native of Pittsburgh, Pennsylvania, Paul is a graduate of Gettysburg College and Duke University School of Medicine, where he earned his medical degree. He served as a medical officer in the United States Air Force from 1963 until 1968. He worked as an obstetrician-gynecologist from the 1960s to the 1980s, delivering more than 4,000 babies. He became the first Representative in history to serve concurrently with a child in the Senate when his son Rand Paul was elected to the United States Senate for Kentucky in 2010.
